Skylanders: Trap Team

Long ago, in the Skylands, there was a group of villains called the Doom Raiders, who spread mayhem wherever they went. Only the best Skylanders armed with special weapons made of Traptanium were strong enough to defeat and capture them, and imprison them in Cloudcracker Prison. They were kept there until Kaos freed them, sending the Trap Master Skylanders in our world, along with the shards of Cloudcracker Prison, which were turned into Traptanium Traps.

The Kaos Doom Challenges are tower defense levels where Skylanders must prevent Kaos' minions from breaking treasure boxes. The Skylanders can build defense mechanisms that attack enemies, earning upgrades for every wave defeated. These levels reward the player with treasures and experience points.
