Zipper Interactive's effort might not be the Vita shooter you're waiting for, but it shows off the systems core potential and looks pretty neat in its own light.
Unit 13 has a couple of cool features thanks to the Vita's connectivity. You'll be given daily mission challenges, receive social updates on how your friends are doing, and even unlock new content for your less-skilled mates if you perform well. The core game has 36 missions and nine "high value target battles", plus WiFi-powered two player co-operative.
The shooter had been expected at Vita's launch, but was pushed back to today in the US and March 7 in Europe.
