Square Enix have decided to try something a little different to everything else that they've been working on -- A twin stick shooter where you battle invading monsters.

0 Day Attack on Earth will take you to Tokyo, New York, Paris and many other locals as you destroy giant aliens threatening to destroying your home.

The game appears to use images taken directly from those cities, similar to what the PlayStation Network game The Last Guy did, and throws giant aliens in the mix. The game also allows up to 4 players to play online in cooperative modes.

It's certainly something different from Square, having all previous downloadable games being quite cheery in comparison. Still it's something we've yet to see on XBLA - a story based cooperative shooter, hopefully people will won't dismiss it entirely because of its shooter aethetic, like they did Shred Nebula last year.
