Microsoft today announced Halo: Spartan Strike, a spiritual successor to 2013’s Halo: Spartan Assault. Like the original, Spartan Strike is a top-down, twin-stick shooter.

The $6 game launches December 14 for Windows platforms (desktop, Surface, and Windows Phone) and one purchase gets you access to the game across all Windows systems. The game is also coming to Steam. What’s more, unlike Spartan Assault, the new game does not feature any microtransactions. Everything in-game can be purchase via credits you unlock through gameplay.

Concerning story, Spartan Strike is set during the events of Halo 2, though that’s the extent of the information provided in the game’s announcement today on IGN.

Spartan Strike will feature achievements, rewards for Xbox One game Halo: The Master Chief Collection, weekly challenges, and leaderboards. Spartan Assault eventually came to Xbox 360 and Xbox One, but it is unclear if Spartan Strike will do the same.

Halo series developer 343 Industries is currently working on Spartan Strike. The studio is also behind upcoming games such as Halo: The Master Chief Collection and Halo 5: Guardians.
