Tripwire Interactive and Mod DB have announced the launch of the Killing Floor 2 Grindhouse Mapping Contest. There's $50,000 in prize money to be won, and the chance to have your creation join the game's official map roster.
Phase 1 began on October 12, and will end on November 30, at 6PM EST - all entries must be in by that date. Those who make it to Phase 2 will have from December 7 to January 31 next year.
All maps must be designed for Survival mode, and must be comprised of only original content created by the modder, or content already contained in Killing Floor 2 and the Killing Floor 2 Editor. Other than that, as long as it's playable with the vanilla version of the game, let you mind run wild.
Or sit back and wait for more creative people to come up with stuff, like I plan to do. Head here for the full details.
