Ginga Force is surprisingly forgiving when it comes to the difficulty, it will reward you with additional 1 Ups for number of enemies destroyed on particular stage. That said, even if you're not that good at dodging projectiles you'll at least finish the game eventually after putting some time and effort.

Even if you struggle with an achievement keep in mind that God Mode upgrade unlocks after spending 30 hours with the game. Equipping it disables achievements for score and time but these aren't shouldn't be a problem if you're already that far.

Clearing stages on harder difficulties unlocks better weapons. Some achievements will be impossible to get on first try, so you may consider trying again after acquiring stuff that hits harder.

SECURE JACK

Simply clear the first stage

CHAPTER 1 MISSION COMPLETE

Destroy all marked parts of the boss' ship. Just destroy stuff before timer runs out. You'll most likely get it without even knowing about the achievement.

SAFETY AHEAD?!

RIght as the stage begins fly to the top right corner of the screen, the boss will instantly skip to next section and the achievement should pop.

TINI SECURED

Clear Stage 2, it's short and easy anyway.

CHAPTER 2 MISSION COMPLETE

Clear Stage 2 after exposing boss' ship, just shoot the drones until they turn blue, if you did everything correctly in both sections and defeat Tini the achievement should show up at the results screen.

SECURITY BREAKTHROUGH

This will be a doozy, you must clear the stage without being detected by the drones or searchlights, using Radar Jammer will void the achievement. There are 2 ways you can go about it: Perfectly learn the pattern of all the searchlights and avoid them for about 1 minute or farm enough 1 ups, let the enemies shoot you all the time so you can abuse invincibility frames after dying. Both methods get a bit easier if Half Slow is equipped.

SECURE GARNA

Clear stage 3 on any difficulty.

CHAPTER 3 MISSION COMPLETE

Take down both missiles and clear the stage, shouldn't be too much of a challenge.

SECURE SERAM

Clear stage 4 on any difficulty, keep in mind, this is the part where stages actually get tough.

CHAPTER 4 MISSION COMPLETE

Destroy all 8 parts of the tank ship, that includes Radar Plate, both Missile Launchers, both Laser Guns and all 3 Ball Turrets. You probably won't be able to get it on the first try, you should be able to do this with weapons unlocked in normal mode run. Personally I suggest Heavy Beam Cannon and Option Bit Quatro, Clear Half Slow also comes in handy.

SECURE GENZO

Clear Stage 5 on any difficulty. While the stage overall is rather easy, boss' ship might give you some trouble. I suggest buying and equipping Debris Destroyer.

CHAPTER 5 MISSION COMPLETE

Your objective is to collect as much Septonium as possible, to do that shoot the minecarts with the yellow shell instead of ones with blue crystals, that way you'll collect the load. From what I've seen you're allowed to miss/ destroy 7 carts and still get the achievement.

SECURE FUAN

Clear Stage 6 on any difficulty

CHAPTER 6 MISSION COMPLETE

Clear the stage after successfully defending the shuttle, to do that you must destroy all spider drones and throw off the boss' mecha before the timer hits zero, this might prove challenging but is possible to do on the first try with a good gear.

BEYOND THE TRUTH

Clear Stage 7 on any difficulty.

CHAPTER 7 MISSION COMPLETE

Clear Stage 7 after destroying both armed Elevator Shafts, shouldn't be hard.

JOINT FRONT

Clear Stage 8 on any difficulty.

CHAPTER 8 MISSION COMPLETE

Clear the stage after destroying at least 30 Security Machines in the tunnel.

OPPOSING DEATH

Clear Stage 9 on any difficulty, keep in mind it's the longest and probably the toughest stage in the game.

CHAPTER 9 MISSION COMPLETE

Clear the stage after destroy at least 30 parts of the boss' ship, both vital parts and turrets count, I suggest equipping Scorpio Tracker or Option Bit Quatro, wouldn't hurt to use Half Slow too.

ORDER OF DESTRUCTION

Destroy the engines in correct order: middle, left, right.

DAWN OF THE SEVENTH TIER

Clear Stage 10 on any difficulty.

JUDGEMENT FORCE TIGER

Clear Combat Training Stage X on any difficulty.

JUDGEMENT FORCE DRAGON

Clear Combat training Stage Y on any difficulty. This one is much tougher than X, I recommend Type C aircraft since it it has Scorpio Tracker and Half Slow.

CLEAR EASY

Clear all stages excluding Combat Trainings on easy mode.

CLEAR NORMAL

Just like before, except tougher. You may consider doing other achievements if you're stuck on any stage, then return after unlocking God Mode upgrade.

CLEAR HARD

This is where things get really challenging, but God Mode makes it trivial.

PLAY ALL SCORE ATTACK CHAPTERS

Self-explanatory.

ONLINE RANKINGS ENTRY

Just clear any stage and upload your score right after results screen.

APPRECIATION

Download replay data of any player in the leaderboards, then watch it.

NICE RECOVERY!

Can be done on any stage, you must have 0 lives, as soon as a 1 Up shows up on the screen let yourself get shot. The 1 Up will save you and the achievement will be yours.

CUSTOM COORDINATION

Start any mission with Heavy Laser Gun, Homing Missile and Counter Shield equipped at the same time.

BACK ATTACK COUNTER

Easiest to do on Combat Training X, fly behind an enemy and spam speed change, the backfire must destroy the enemy and the achievement should pop.

PLAY ALL STORY MODE CHAPTERS

Play every stage on any difficulty, that includes both Combat Training stages.

BREADWINNER

Get 1M credits, should pop about halfway through normal mode run.

FULL GUARD

Get maximum 30 1 Ups on any stage, you can do it fast on Stage 10.

TIME ATTACKER

Get under 1 hour of overall clear time in all stages, prefferably on easy. You'll most likely have to cut about 10 minutes from your normal time but it should come easy after getting better weapons.

BECOMING A VETERAN

Get 500M total score, fastest to grind on Stage 10, it should earn you about 1-2 M per attempt. The score doesn't count when using God Mode.
