Meridian: New World is a pretty hard RTS, some achievements might looks impossible, if you tried the game but with my tips and tricks you might be able to finish it to 100%. You will see all achievements in this guide, ordered by how and where to get it.

There are 83 achievements in the game:
Commander levels: 6
Hard AI: 11
Loyaltly+combat trainings: 8
Regular skirmish: 16
Campaign: 33
Simple Achievements: 5
Traces of Squad 22 Mission: 3
Credits: 1

There are achievements for reach lvl 5, 10, 20, 30, 40 and lvl 45.

This is the first part of my guide and farming exp is very important, you can unlock abilities and some of them will be very important. You will get a lot of exp on your campaing walkthrough however also a lot of farming required to reach 40 and lvl 45. Ill share you the method i found for the fastest exp farming for the game, however its require some preparation.

In your campaign you will get to a mission (mission11) where you can build up a base without being attacked. There are still 6 huge waves of enemies but they will attack you at the time of your choise. 8 turret centers were enough for me to build up enough firepower to beat all waves. While your units mining for the required amount of shardiums, use your lvl 2 extra power abilities all the time to increase the power of your power plants, so you need to build less buildings. For unit choise i suggest heavy chimeras, equipped with sniper weapons and in laboratory you also need to unlock the anti air rocket ability for heavy chimeras. As the units move to the center of your base after each map, which would be time consuming to move them back, just build your chimeras inside the turret wall, so they cant move away. Once done save, call the waves (all 6 should be killed, you dont need to interfere) and then just reload your game and repeat. All 6 waves should be around 1100-1200 exp in a few minutes (if we dont count the base build up time, but you need to beat the map anyway for campaign progression). First wave isnt that much exp so if you wish you can kill your starter units with that wave so you can build up more heavy chimeras and farm just waves 2-6.

This is how my wall looked after starting the waves:

Beating a HARD AI on skirmish map is impossible, at least i thought so for a long time.
By the time you manage to build up some infantry enemy already producing panzers, AI just cheating like hell, impossible to build up that many armies and get enough shards for that many units. Then once i tried a solution i had in my mind and it worked, so ill share my secret to you guys.

The tactic require you to have some commander abilities, which is at least lvl 1 Reveal (but lvl 2 is better) and you also need at least lvl 4 Conflagrate (the one which damage buildings).

Right after you start a skirmish match against hard AI move the map to AI start position, reveal the area for 25 energy and dmg the shardium mine for 70energy with conflagrate. Move back to your base, build 1 infantry barack and 1 power plant, make the other 2 unti to mine shardiums. Once the other 2 units done with construction send them to mine shardiums and mass produce infantries. Once you can, with one miner chimera build up a second barack and mass produce infantry units with that one aswell. As soon as you have again full energy repeat the exact thing you done at the start, reveal enemy base and damage the shardium mine with conflagrate. Keep building infantires, kill the incoming waves (focus your firepower on single units) and once you have again max energy finish off the enemy shardium mine. With this AI is literally killed, it wont produce any more units, as he focusing on army production AI dont have shardium to rebuild shardium mine. Produce some more infantry, reach 15/15 pop cap and move your army to the enemy base the destroy the remaining buildings (some leftover army will still be there.)

This method should also unlock the win against Hard AI within 10minutes achievements and as there are 10 acheivements for beating Hard AI on 10 different skirmish maps we done with another 11 achievements pretty easily.

Loyalty Master asks you to get 12/11 loyalty in the same campaign walkthrouh, so here are to points you can earn in the campaign:

- Right after the campaign start choise "we're not leaving until we investigate this" when you on the board of the Magellan once your crew discover the broadcast from a femal human.
-Do not offend Donovan by claiming he could be the traitor or if you do, you will have a chance to apologize him later so use that oportunity. Offending Donovan without apologize is -1 Loyalty.
-Do not destroy the enemy base at the end of the third mission. Choising to destroy instead of sneaking will be -2 Loyalty.
-+1 loyalty for finishing each of the combat trainings, there are 9.

Jenny related loyalty points (need to get 2/2 with Jenny for the achievement while she also need to stay alive on last missions)

- Talk to Jenny when you are on the Magellan for the first time. Ask her about her theory. Agree with it (+1 loyalty point)
- Talk to Jenny when Cole is in holding and ask her if she talked to him (+1 loyalty point)
- Tell her to keep you posted when you talk to her the last time you're on the CCS Magellan (this is also +1 point, but only if you don't have 2/2 already)

Dont make it sure always you exhaust all conversations with everyone always, stick to one route especially in the above mentioned situations. Visting everyone and every interactable points after each mission is a good way to get all achievements and loyalty points tho.

The Combat missions:

For these all you need is patience, might be time consuming to add extra armor at start for each unit via commander ability, heal every time and wait for max energy again before engaging next combat so you will have extra firepower or healing abilities ready.

Some ask for finishing it in X time, those are hards, but not impossible, you will handle it, no special tricks for that unless for Scout rush where you need to rush to power plant without fight and use extra firepower on any unit survive to that point so it can destroy the power plant.

Scout Protector
Do not lose a single Scout in the second Scout simulation.

Chimera Saver
Do not lose a single Chimera in the third Chimera simulation.

Survivors
Do not lose a single trooper in the first trooper simulation.

Chimera rush
Accomplish the second Chimera simulation in less than 1:20.

Scout rush
Accomplish the first Scout simulation in less than 35 seconds.

AND:

Simulation Completionist
Accomplish all simulation missions.

Dont be a fool and just finish them against easy AI. Easy AI wont produce sniper untis (at least i not seen any) or heavy units, neither aircrafts so a good turret wall will destroy them and you can just watch TV or something while AI gets depleted on shardium. As you need to play one skirmish for 1hour long it is suggested anway. Not much to comment here, all achievements pretty straightforward and dont require exceptional skills. I'll list the achievements for the skirmish maps and add a few comments to a few achievements, but these really not hard.

Aggressive
Have at least two Shardium Mines in the first 10 minutes of a skirmish match.

Producer
Produce at least 25 units in a single skirmish match.

Shardium Collector
Mine 20 000 Shardium in a skirmish match.

I can do both!
Own a Landing Pad and a Heavy Factory by the end of a skirmish match.

Economy Master
Collect at least 1200 Shardium in the first 10 minutes of a skirmish match.

As i experienced you need to have 1200 not just collect.

Mass Producer
Produce at least 50 units in a single skirmish match.

All your base are belong to us!
Expand to three locations in a skirmish match.

This means to have 3 shardium mines.

Shardium Hoarder
Mine 30 000 Shardium in a skirmish match.

Little-loser
Win a skirmish match by not losing more than 10 units.

Heavy army
Own six Heavy Chimeras during a skirmish match.

Maxed out
Get 60/60 food in a skirmish match.

You took your time
Play a skirmish match for over one hour.

Flawless Victory
Do not lose a single unit in a skirmish match.

This one might be challenging but if you cant do it against easy AI then you should play hello kitty online instead:-) You actually need to survive the early phase, build turrets fast so they can kill waves and move your untis away from the frontline and order them to stand still. You can then just kill the enemy base with the method described in HARD AI part of the guide.

Early Game Master
Own at least five Chimeras with Charger Cannons in the first 10 minutes of a skirmish match.

Build laboratory and develop this technology fast.

Suicidal
Lose a skirmish map in under 5 minutes.

Demolish your starter buildings and wait until your starter miners gets killed or start to move them to the enemy base.

I like this new one!
Beat a skirmish map by producing Manticores and nothing else.

This is probably the hardest and not possible against anything else than easy AI as on other difficulties enemy arrives before you could even produce your first manticore.

This part is pretty straightforward, so ill just list the achievements and comment it if its harder or require some special task, ill try to do it in chronological order as they could be earned while progressing with the campaign. In some missions you cant finish all tasks in one go, dont panic, once you farmed enough exp with my above mentioned method you can just go back to the mission, just save and go back to that mission later.

Not all achievements sorted to the exact prder when it become achievable, i dont remember when it happened exactly for some and i dont want to place to wrong one but if you playing the game please comment where it was exactly and i move it to there so the list will be chronologically complete! Thanks
