Here's an announcement video for Halo: Spartan Strike

Yesterday, Microsoft announced Halo: Spartan Strike for release on Windows 8 devices and Steam. Today, the firm has released a trailer for the follow-up to last year’s Halo: Spartan Assault.

The top-down twin-stick shooter will contain weekly challenges in which players will contend for the top slot on the leaderboards.

Those who play Spartan Strike will also earn Xbox Achievements which unlock content for Halo: The Master Chief Collection, which launches on Xbox One November 11 in North America and November 14 in the UK.

Set during the events of Halo 2, the Vanguard Games-developed title will run you $5.99 on Steam and Windows devices when it releases on December 12.

Below is a list of key features, per Microsoft:
