For the "Untouchable" in-game achievement it just says "complete a legion without losing a life." I'm not talking about the Kongregate "Burning Legion" badge.
I have completed the small legion twice without losing a life and I did not get the "Untouchable" achievement. I did, however, lose a shield both times. Does that count as losing a life?
Absolutely horrendous game. This is the first comment I've ever left on a game, but I felt it necessary because my the anger and frustration induced by playing this game makes the experience so unenjoyable that I must plead to anybody even considering attempting the badge to spare themselves the extreme waste of time. This is the first game I have wished for a 0/5.
