But luck is an important factor TOO I lost parts because of the chance:
5 shots to 95% success = 0 successful. The robot makes him two shots of 6 = 3 dead in my team (and death is final in this game).
So we spend time to load our backup and start over, which adds spice: the enemies are never in the same place when you save during the game, and the cards are never the same.
In short the chance and failed to kill me the pleasure of playing in late or certain enemies can kill in one hit your soldier.
