Coffee Stain Studios will give the winner of their Sanctum Survival Contest the chance to create their own level, the studio announced.
Sanctum is a tower defense and first-person shooter hybrid. Players spend their time building structures and defending against oncoming alien forces. The contest, which is currently underway, challenges players to survive the game's Corporation map in Standard Survival mode at the Hard difficulty. The player who endures the longest, wins; scores are posted via screen-shots on the official forums.
The player-designed level will be added to the game as free DLC. Sanctum Survival will come to an end at 11:59 CET on October 22. The full list of details can be found here.
