Dead Nation has infected a seemingly random selection of PSN members with a surprise beta starting today.

The latest in zombie survival horror gaming is a dual-analog shooter developed by Housemarque, expected to launch this year over PSN.

An unannounced beta code was sent via email to a selection of PSN subscribers today, apparently regardless of PlayStation Plus membership.

The beta will run through September 3 and is hosting two “free play” scheduled events, one today at 12 p.m. US PT and the other August 26 at 2 p.m. US PT, one lucky writer for Destructoid detailed.

Dead Nation will support co-op, but the beta keeps it simple with a solo campaign and a choice between two characters, Jack McReady or Scarlett Blake. The beta is being tracked on global leaderboards, so if you have a code, get shooting and let us code-less wannabes know what you think of the game!

Everyone else, check out the trailer right here and whine about the lack of a good beta in your lives right below!
