Here's my entry!
Shambling explosive unit. On death, AOE discombobulates survivors, making them scatter and attack each other.
Preview is kinda small. May want to right click it and view image in a new tab/window or download. Hope you guys dig it! Thanks again to the Devs. Great game, fun contest ;]
At low levels he causes survivors caught in his blast radius to walk in random patterns and lose strike accuracy- meandering away from protective formations and losing combat effectiveness as well. At higher levels once his perks have really started stacking, getting caught in his noxious gooey remains causes survivors to scatter and even attack one another in a fit of hallucinatory confusion.
