Since Player 3 already opened the door, I may as well move into player 2's space and attack his Walker. I don't have a ranged weapon, so if i dispose of the Walker he found, he can concentrate on the Walker in the spawn zone.
Action 1: Move N.
Action 2: Attack Walker with my axe. Roll 3 = fail.
Action 3: Try again. Roll 3 = fail.

Well that was useless!
