Deathtrap is a Tower Defense game with strong action-RPG elements, a game of vicious tricks, killing machines, rotating blades and splattering blood. It shares the gothic fiction setting with NeocoreGames' The Incredible Adventures of Van Helsing and features a lone protagonist who is sent to a border world in an alternate dimension ("Ink") to defend a series of ancient strongholds against a horde of monsters invading from the depths of that dimension and trying to break through to the physical world.

Beyond the veil of this world, there is a chain of strongholds that were once built to keep the horrors of the void at bay. And now the monsters are returning from the depths to conquer and kill: only you can stop the monsters before they break through to the everyday world. Choose your hero and defend the silent forts: use, rebuild and improve those ancient traps and magical machines.
