Josif Stalin, Karel Marx, a baby, Christmas, sheep, social workers, the army. The first two are protecting the third from the rest. Piss take theme (communists in Christmas?), taking the piss of a game genre (Tower defense, although it's really not boring as a traditional tower defense, you just select your weapon and it's shot directly - no boring decisions about where to place your defenses) from McPixel author with really ridiculous dialogs. There's even an Outrun minigame and the weapons screen includes a Mad Max tune (although it's been bastardized with SID vocals ;))! So what are you waiting to try it out?
