Unit 13 releases on Vita in March

Zipper Interactive's Unit 13 won't quite be ready for the Vita launch--but it will be pretty darn close. Unit 13 will be available on Vita at retail and on PSN on March 6th.

Unit 13 is an online-enabled shooter that lets you play a variety of short missions. There are four mission types: Direct Action, Deadline, Elite, and Covert. While there is no online competitive play, unlike Zipper's other shooters, there is online co-op, and a persistent leaderboard that can be updated via 3G.

The PlayStation.Blog has a video walkthrough of a Covert mission:
