Deathtrap is a game that takes you to a netherworld where you have to defend ancient traps and magical machines from monsters trying to break through to the everyday world. This Tower Defense game has strong action-RPG elements, making it a unique mixture of both genres.

The game offers a single-player campaign where you can use your deadly devices and powerful spells to defeat hordes of monsters. You can also team up with other heroes and play the cooperative campaign with specially designed maps. Alternatively, players can set against each other in the game mode where the defender prepares traps and defensive tactics, while the attacker has the ability to possess and control any creature in their army. Deathtrap also has an integrated Map Editor and Monster Editor that allows the creation of user-generated content, which can be shared with others.
