The third closed beta event is scheduled to kick off at 12:01am Eastern Standard Time and not a moment later. The weekend of war will end on Sunday September 9th at precisely 11:59pm EST.
The event will introduce Elite Companies, pre-configured armies that all players can hire and throw straight into their battles.
You can sign up for access to the beta through the official website or try your luck at claiming a key by badgering developers Trion through the game's Facebook page or on Twitter. Naturally, anyone who's purchased an early edition of End of Nations will already have beta access, and you can grab one either from Trion or, if you fancy some extras, Green Man Gaming have a Founder's Edition with all sorts of goodies and exclusives.
