I've played Death Angel and really love it. Huzzah FFG! However, I have yet to lose a game - whether solo, 3, 4, 5 or 6 players. I've played several games where not a single Marine was killed. What gives? Initially, we were misinterpreting the rules (e.g.: the whole swarm moves versus just genestealers with the tail symbol; a die face with a "3" and a skull does not equal 3 kills) but I'm reasonably confident we are now playing correctly and yet...we just don't seem to lose.
Again, I love the game but without the threat of a TPK, I'm afraid it will lose its appeal. Should I expect to lose occasionally (at all)? Is it likely that I'm still misinterpreting the rules?
