oh yeah, if an enemy dies while on fire, it should leave a little burn pile of ashes, and if it dies while frozen it should shatter into little bits of ice, and if it dies while poisoned it should vomit and curl up.
i think the sniper tower fires too rapidly, the ice, fire, and poison towers do to, but they arn't powerful enough for it too matter. Slow them down, but make their effect abilities happen more often. More poisons and more freezes etc.
man, how do you do the mission where you have to fight army regiments? they all have zooka's and grenades and most of them attack before all your guys do.......
