A glitch exists if you use overpowered soldiers and buff them with the beer guys. I have done this a few times buffing 60% attack with the chiefs, which destroyed the enemy so quickly that their health went negative. After that they just stand there and you are forced to restart the level.
This game was fun for about five minutes, but quickly became annoying. Useless powerups, cheap deaths and an overly cluttered screen result in the worst infectonator game to date. Disappointing.
