Capybara Games’ long-in-development Super Time Force will release simultaneously for Xbox 360 and Xbox One on May 14, Capy President Nathan Vella announced yesterday on Twitter.

A launch trailer published alongside the release date announcement displays a robust cast of wacky playable characters for the side-scrolling shooter. Among the newcomers is Merlin of Arthurian legend and Dolphin Lundgren, a dolphin named after action movie star Dolph Lundgren. Several new stages are also highlighted in the video, including a medievil castle and a speeding locomotive.

The trailer focuses heavily on the fact that anyone who plays the game can expect to die early and often thanks to its seemingly never-ending onslaught of enemies and projectiles. Super Time Force‘s steep difficulty is offset by the game’s main hook: the ability to rewind time prior to the point of death, select another character and play alongside the versions of the player character that have previously died. Capybara refers to this mechanic as “single-player co-op.”

The studio originally planned to release Super Time Force on the Xbox 360 in 2013, but delayed its debut so that it could release an Xbox One version at the same time.
