This guide is divided into sections for quickly jumping back and forth between different types of achievements and information. You can also do a ctrl+F search with the achievement name to instantly jump to that.

If you miss any achievement, you can simply go back to a CHAPTER/MISSION from menu to unlock what you need. And all achievements can be achieved in one save file too. No need for multiple playthrough for achievements.

The developer did a really good job with the music. Yet sometimes, I was listening to Origa – Inner Universe and Scott Matthew - Lithium Flower from Ghost In The Shell: Stand Alone Complex OST+ in the background.

Let’s begin.

The following achievements can be unlocked just by completing MISSIONS and CHAPTERS.


First_win: Self-explanatory. Unlocks when you win your first tutorial MISSION.


Chapter 0: Self-explanatory. Unlocks when you win all MISSIONS in tutorial CHAPTER.


Chapter 1: Self-explanatory. Unlocks when you win all MISSIONS in CHAPTER 1 GROUND ZERO.


Chapter 2: Self-explanatory. Unlocks when you win all MISSIONS in CHAPTER 2 THE DARKNESS.


Chapter 3: Self-explanatory. Unlocks when you win all MISSIONS in CHAPTER 3 GRAND CANYON.


Chapter 4: Self-explanatory. Unlocks when you win all MISSIONS in CHAPTER 4 WALKING THE LINE.


Chapter 5: Self-explanatory. Unlocks when you win all MISSIONS in CHAPTER 5 BREAKOUT.


Chapter 6: Self-explanatory. Unlocks when you win all MISSIONS in CHAPTER 6 FRONTIER.


All Stars: Self-explanatory. Unlocks when you win all MISSIONS in all CHAPTERS with full stars.

If you are struggling with certain MISSIONS, take a moment to consider a few things:

1. Always upgrade skills for your OPERATORS to the max whenever they become available. Upgrade in this order KICKSTART, ORGANIZE, REINFORCE, REBUILD. Also unlock more blocks for them to get better results from ORGANIZE skill. If you are struggling with FORCE, see the section “Struggling with Force?” in this guide.
   
2. You can max your range attack with 3x BUILDINGS, melee attack with 3x BUILDINGS, movement speed with 3x BUILDINGS, CREEP purging speed with 3x BUILDINGS, health and shield with 3x BUILDINGS. Total 15 blocks to make you formidable against enemies. Or you can get all of this and some more with in 9 blocks using OLYMPUS. If you don’t know what OLYMPUS is, see the section “Unlocks: Hidden Buildings” in this guide.
   
3. Don’t waste COAGULANT at the wrong time. Activate it when there are many enemies in screen and you want to freeze them for a significant amount of time. Bosses will only get slow. You if don’t know what COAGULANT is, see the “Unlocks: Hidden Buildings” section of this guide.
   
4. Some WEAPONS and SPECIAL just feel awesome and you love them. Great. But same WEAPONS and SPECIAL will not win you all missions. Change your tactics for what works better against different bosses and their movement pattern in different MISSIONS.
   
5. Prevention is better than cure. There is no point in constantly struggling to repair your BUILDINGS or running to DISINFECTION and BEACON buildings, not to mention watching them getting destroyed and then running for REBUILD (REBUILD is limited for OPERATORS). Based on the elemental attacks from enemies and specially the bosses in a MISSION, you can make good use of BUILDINGS like FIRE_RESIST, ELEC_RESIST, P_RESIST, BREAKAWAY etc. MEDIVAC airships are also useful as they auto repair you, your summons, and BUILDINGS.
   
6. When you are rich, you can have lots of friends and this game is no exception. When you have enough MINERAL, your summons can be your best friends in this game. Instead of relying fully on towers, which cannot move and often times find enemies out of their range, stock up on MINERAL fast, maintain the MINRAL income flow and let PHOENIX, THUNDERBIRD, MOTHERSHIP airships, and BATTLECRUISER handle the offence and defense while you can get some time to focus on placing your BUILDINGS, purging CREEP, or repair jobs. You if don’t know what BATTLECRUISER is, see the “Unlocks: Hidden Buildings” section of this guide.
   
7. How about turn the tide on Zerg rushing enemies and give them a taste of their own medicine? Maintain the MINERAL income flow and make abundant use of CALLFORTH and LABORATORY when their number grows to keep them busy enjoying their own medicine.
   
8. Purging CREEP as much as you can is important to get all stars in a MISSION, but purging a single block of tile also speeds up the boss countdown timer by one. For CHAPTER 6 MISSIONS, use RAPTURE to purge CREEP instead of dong it manually. One single use of RAPTURE cleans up a significant number of tiles from CREEP and yet speeds the boss countdown timer up by only one. This gives a very important time to finish your BUILDINGS and stock up on MINERAL and SPECIAL before bosses show up.
   
9. For the last mission MISSION-6-E, nearing the very end of fight, if you still run out of MINERALS for spamming FATMAN, you can hit your panic button. I mean the bombardment option from pause menu, which requires TECH points and the price keeps increasing slowly with every bombardment call. Hope you saved up enough TECH points.
   
10. Anyone has other suggestions? The comment section is all yours.

Here are some of the DEPLOY loadouts I used for the three difficult MISSIONS of this game. These are by no means the best, but they worked for me.

MISSION-5-E

MISSION-6-D

MISSION-6-E

You DO NOT need another person to play as player 2 to get the next two achievements. You’ll need to build a P2_BASE and a new hovercraft will appear. It can auto shoot. So, you can move and place it in a good position to auto shoot or to collect resources.


Two players: Unlocks when you win a MISSION or enemy battle for the first time with the BUILDING P2_BASE present.


Max p2: Unlocks when you build three P2_BASE BUILDINGS during a MISSION or enemy battle for the first time.

In DEPLOY screen, you can open any OPERATOR’S detail by click and holding their thumbnail image under OPERATORS tab. Here you can upgrade their skills if upgrade is an available and you have enough FORCE coins to purchase that upgrade. More skill upgrades become available throughout the game as you keep purging CREEP. OPERATORS can have 5 skills each of which can be upgraded twice:

• REINFORCE
  
• ORGANIZE
  
• REBUILD
  
• INSURE
  
• KICKSTART

KICKSTART and ORGANIZE are game changers and you should invest FORCE on them as early as you can, specifically KICKSTART first. Then invest on REINFORCE and REBUILD as enemy keeps getting stronger with MISSIONS.

Also in DEPLOY screen, you can see all your available BUILDINGS under BUILDINGS tab. Here you can increase the number of any particular BUILDING to be used for deployment. These BUILDINGS are categorized into:

• A: FOUNDATIONS
  
• B: SKILLS
  
• C: DEFENSES
  
• D: WEAPONS
  
• E: SPECIAL
  
• F: SECRETS

BUILDINGS are unlocked by purging CREEP during MISSION, completing PUZZLE, and completing SIGNAL GAME.


Operator's skill: Unlocks when you upgrade any skill of any of your OPERATORS for the first time.


Operator's 2 skill: Unlocks when you upgrade any skill of any of your OPERATORS twice for the first time.


Grid_6: Unlocks when you unlock 6 blocks for any of your OPERATORS grid for the first time.


Grid_9: Unlocks when you unlock all 9 blocks for any of your OPERATORS grid for the first time.


Building 7: Unlocks when you increase the deployment cap of a single building beyond 7.


Building 20: Unlocks when you increase the deployment cap of a single building beyond 20.


Deploy_3: Unlocks when you have three slots for you DEPLOY saves. If you can’t find where and how to increase, click DEPLOY_LOAD and then click on the + to add more (needs FORCE).



All Buildings: Unlocks when you obtain all BUILDINGS from completing MISSION, PUZZLE, and SIGNAL GAME. There is also a SIGNAL GAME in ENDLESS mode screen, which will unlock an additional building if you are missing one.

For the SIGNAL GAMES, don’t forget the signal locations and roam aimlessly in the map. But if you do want that, then you do you, all the power to you. Otherwise, you can just take a photo and use that as a reference, not cheating.

“Do you guys not have phones?” – Corporate Commander representative from Blizzard, Blizzcon 2018

All BUILDINGS unlock locations are available below.

HIDDEN_BUILDINGS are discovered when eight specific buildings are placed in nine squares in a circular pattern while keeping the center square empty. The HIDDEN_BUILDING is then created automatically in that empty center square. It doesn’t require you to place those eight BUILDINGS in any specific order about which BUILDING should go in which outer square. Once you discover a HIDDEN_BUILDING, it is added in your DEPLOY screen’s BUILDINGS tab under SECRETS category to be used directly as template in future.

Remember to leave the center square empty. Otherwise, these will not work.

Rescued: Unlocks when you explore a wreck for the first time.


Big fire: Self-explanatory. Unlocked when you use the FIREBALL skill for the first time.


AT_field: Unlocks when you place BUILDINGS in all blocks of a row for the first time and AT_FIELD gets activated.


Purification: Self-explanatory. Unlocks when you purify a CREEP for the first time.


Signals: Unlocks when you successfully finish your first SIGNAL GAME in CHAPTER 1.


Rebirth: Unlocks when you respawn for the first time in game. It requires that you have a REVIVE, which the game gives you one for free in every MISSION at later CHAPTERs.


Building explored: Unlocks when you explore a BUILDING for the first time in game through purging CREEP.


Lode explored: Unlocks when you discover a MINERAL vein for the first time in game while purging CREEP.


Puzzle explored: Unlocks when you discover a PUZZLE for the first time in game while purging CREEP.


Radar: Unlocks when you build a RADAR for the first time in game.


Invincible: Self-explanatory. Unlocks when you build INVINCLIBLE for the first time in game. INVINCLIBLE makes you invulnerable for some time.


Incantation: Unlocks when you build any of the HIDDEN_BUILDINGS for the first time in game.

Rhinobeetle: Unlocks when you defeat the boss RHINOBEETLE in MISSION-1-A.


Drone: Unlocks when you defeat the boss GIANT BEE LARVAE in MISSION-1-C.


Queenbee: Unlocks when you defeat the boss GIANT BEE in MISSION-3-E.


Wisteriabug: Unlocks when you defeat the boss WISTERIABUG in MISSION-4-B.


Ringworm: Unlocks when you defeat the boss RINGWORM in MISSION-5-C.


Invisible: Unlocks when you defeat the boss PHANTOM in MISSION-6-A.


All Enemys: You DO NOT need to hover over each and every enemy thumbnail in all DEPLOYMENT screens to open their DNA information. When you have successfully finished all MISSIONS, all enemy DNA information have become available under ENEMY_DNA screen from INFORMATION > ENEMIES menu. Just open that ENEMY_DNA screen after all MISSION completion to unlock this achievement.


Battle: Unlocks when you win a battle from ENEMY_DNA screen (INFORMATION > ENEMIES menu) for the first time in game. In these battles, you have only 3 rows to place BUILDINGS and the enemies flood you. But these are easy when you have a tactic in mind. Just make sure the OPERATORS you are bringing in have KICKSTART and ORGANIZE skills upgraded to max as there is no time to collect MINERAL and very little time to place BUILDINGS one-by-one. REINFORCE skills maxed out will also be helpful for stronger or ranged enemies. Also, don’t forget to bring two OPERATORS with 9 blocks unlocked to help speed up with ORGANIZE skill.
For example, it is easy to cheese many of these BATTLEs with the following DEPLOY loadout. With this DEPLOY you quickly pick up some enough MINREAL from your KICKSTART to build the COAGULANT in one shot. Then pick up the rest of MINERAL to build BATTLECRUISER while COAGULANT is charging up. COAGULANT will be fully charged before enemies doing big damage to your BUILDINGS. If the enemies start doing damage and your BATTLECRUISER is still not built, just activate COAGULANT and then finish BATTLECRUISER and the rest of your BUILDINGS. Just mind on picking up MINERAL and activating COAGULANT and let the BATTLECRUISER clear the screen for you with its L+ beam and massive homing attacks. You can also join the fun with your L+ beam drops too. After a while, MINERAL and enemy FORCE drops will start to fly to you. Again after a while, the enemy will drop a win pickup. But don’t pick it up and keep letting the FORCE drops fly to you until the point where the win drop flies to you to ending the battle.




Flyingdevil: Unlocks when you defeat the following enemy from ENEMY_DNA screen.


These are fast and ranged enemies. I used the following DEPLOY tactic for this battle.




Locust: Unlocks when you defeat the following enemy from ENEMY_DNA screen.


These are strong enemies with continuously dropping fire balls rolling to your buildings. FIRE_RESIST and CRYO_TOWER are keys for this battle. I used the following DEPLOY tactic for this battle. If you can’t hold long enough to wait for the win drop to fly to you, just activate INVINCLIBLE and then go straight to the win drop to pick that up. I used the following DEPLOY tactic for this battle.




Flydragon: Unlocks when you defeat the following enemy from ENEMY_DNA screen.


These are fast and will attack from top and bottom instead of right side. Your BUILDINGS placements should be accordingly. FIRE_RESIST and CRYO_TOWER are keys here. I used the following DEPLOY tactic for this battle.

PUZZLES are in the menu RESEARCH. When you are solving these PUZZLES, pull yourself back to make enough distance between your eyes and the monitor so that you can visualize the scenario easily. If you can visualize the entire thing in your mind properly before starting, it gets a lot easier. I was able to solve all of them in 4 to 8 moves.


Puzzle: Self-explanatory. Unlocks when you solve your first PUZZLE in the game.


Airplanes: Unlocks when you solve PUZZLE numbers 1 to 5.


All Puzzles: Self-explanatory. Unlocks when you solve all the PUZZLES. PUZZLE discoveries are available in the following maps. If you miss one, you can come back and use your scan ability (which becomes available later in game) from DEPLOY screens to scan grids (requires FORCE) to pinpoint a PUZZLE location in maps.


PUZZLE numbers 1 to 5 are comparatively easy to discover. But it gets difficult to manage time to discover PUZZLE number 6 to 9 as purging CREEP that far in the right when working on your BUILDINGS. Also, considering the amount of CREEP you need to purge just to make space for your BUILDINGS in later MISSIONS without using RAPTURE (which drops at after MISSION-5-E), it speeds up the boss countdown timer and make it challenging to even reach to PUZZLE discovery.

The developer has provided clues in INFORMATION > CARDS menu to pinpoint PUZZLE locations for CHAPTER 5. Do these cards content show something similar to certain MISSION maps and what are those glowing blocks? 🤔

If you are still struggling, here are the locations and solutions to all PUZZLES.

Puzzle #1: MISSION-1-C



Puzzle #2: MISSION-2-B



Puzzle #3: MISSION-2-E



Puzzle #4: MISSION-3-E



Puzzle #5: MISSION-4-E



Puzzle #6: MISSION-5-A



Puzzle #7: MISSION-5-B



Puzzle #8: MISSION-5-C



Puzzle #9: MISSION-5-D

If you have finished all the MISSIONS and have all BUILDINGS unlocked already, then the first 9 levels in ENDLESS are no challenge to you at all. It only starts to get challenging from level 10 onward.


Endless 2: Self-explanatory. Unlocks when you survive level 2 of ENDLESS.


Endless 12: Self-explanatory. Unlocks when you survive level 12 of ENDLESS.

If you keep struggling with lack of FORCE to upgrade skills or unblock grids for your OPERATORS, or to upgrade caps for your BUILDINGS, or to scan grid in DEPLOY screen, try to battle enemies in ENEMY_DNA screen like I showed in "Achievements: Enemy Related" section.

You can also do some shady financial investment experiments, for science of course. Here is an example experiment I did for easily generating around 10000 FORCE in one CHAPTER 2 MISSION.

Feel free to do more experiments. How about 2x COAGULANT and 3x BATTLECRUISER show for some entertainme-, I mean for science, of course.
