And just like that, SCEA has begun sending out invites for a Dead Nation
beta. We're not entirely sure what online functionality the beta is testing, especially considering the rather lax requirements for the program -- "All you need to do is make sure you are signed in to the PSN while trying to kill as many dirt-ridden flesh sacks as possible!"
The beta is currently ongoing, and will end on September 3, giving invitees over a week of playtime. The invites appear to have been sent randomly, so check your e-mail (and your spam filters) to see if Sony has invited you into this unexpected preview event.
