Checkmate!
Defeat Ice Trumper in direct battle
He's the mid-boss of the Northern Base level. You have to defeat him in direct battle, meaning you have to destroy him before he destroys the ice blocks and falls to his own death.

Bye Bye!
Lure Ice Trumper jump to the pit
Just let him destroy the ice blocks and fall down into the pit by avoiding his attacks long enough.

Reactor Breaker
Destroy All Reactor in fleet level without using Glora
This can be tough, but it is doable. Glora is the ride armor that you can use in the level where you fight Ubermind but you must avoid using it while destroying the reactors. I'm not sure if getting in and out ruins the chance of getting this achievement but I'd say stay away from it just in case.

Glad to know this achievement really work!
Defeat Origin Titan in hard difficult without using recovery power and Glora
Without a doubt, the hardest achievement in game. You obviously need to buy the skill that you can overclock your abilities for this one. Stay away from him, avoid his attacks, and keep an eye out for the health pickups that spawn around the area and make sure to revive your buddies, too! Here's a video by chucknorris078 that demonstrates how to do it but it is an RNG based achievement regardless.











Meta Arena?
Defeat Aeon in Sky ladder using Erika Flame kick
This is missable. You need to land the final blow on Aeon in Sky Ladder using air dash as Erika to get this one.

Road Rage!
Kill enemy with bike kamikaze
This is a very easy achievement to get but it is missable. You need to jump off of your bike in Desolation Desert and kill an enemy by crashing it into them.

I remember that move!
Find and defeat Aeon 4 times in different levels
He appears in 4 levels in total, and 2 of them are missable. Check out my other guide for this one.
