Alte is a new character which I find cute, yet sad to play as. (In a good way)
Her achievements I quickly found out thanks to some amazing friends

Also thank you to those who found other ways to get the achievements and confirmed some theories

News: As of 16th August 2015, Alte's hyper is now level 3 but caan be used at any HP
--------------------------------------------


Rebellion "Won't be bossed no more" - KO a boss with your hyper

This one is pretty easy if you put in Long-Distance Shot and have some friends to help you. As long as the boss KOs you (so defend) you will get this. Pretty sweet trap ey?


Full Payback "Boom Boom Boom" - Get +3 Attack

For this one you need to die using your hyper 3 times, each time you die with it, you are given +1 attack. Again same as the Rebellion achievment, have Long-Distance Shot and have some friends to help you with this as attacking normal enemies after your first death may end in KOing them and wasting your card.

Having a "Of My Friend" card will help because then you are sure to not kill the boss so he can KO you instead.

--------------------------------
Tips
Put in some Long Distance Shot cards
Cloverfield or Practice Field are good to use
Defense cards may help lower your HP easier
Force Revival will help you get to 1 HP if the plan failed
--------------------------------


You Call That A Trap? "What a piece of junk..." - Don't land on any traps

Don't land on any trap cards, you don't need your hyper for this but your hyper can cancel them out for extra security.


Total Barrier "Going down without a fight" - Don't Die To A Player + Win

Confirmed that you must win a game without being killed by another player. Dying to a Red/Boss panel enemy seems to be fine, as long as it is not another player. (The CPU counts as a player)
You can use your hyper and still get this so you can work on both of her achievements at once if you are lucky

I suggest Cloverfield and packing some Cookies, Tactical Retreat & Shield Counter if you cannot find 3 friends to help you with this safely.

--------------------------------
Tips
Put on Regeneration & Minefield events
Cloverfield or Practice Field are good to use
Saki's Cookie cards will also help if your friend is being a jerk and trying to kill you
--------------------------------

The 3rd achievements for both of them is to play as them 10 times in Multiplayer. No long description needed here.
Goodluck hunting everyone.


I know there is an achievement guide on the forums already but the poster says he cannot edit the guide so I hope this helps. Of course all achievements are easier with friends.
