Trion Worlds announces the Defiance will commence a third (and final) beta event next weekend, as they prepare this TV tie-in MMORPG for release. Players can guarantee a spot in the Windows beta by preordering the game through Steam, and word is Trion will also be offering beta access to the Xbox 360 and PlayStation 3 editions of the game, with exact details on console testing to follow. Here's word:

Participants in Advanced Mission Beta 3 will get to play as Ark Hunters. Genetically enhanced with unique abilities and armed to the hilt with a variety of unique alien and human weaponry boasting thousands of upgrade options, Ark Hunters are fearless operatives who scour the Earth competing for alien technology against all odds for vast rewards.

The final beta, which is not representative of the final game, will let players explore the Mt. Tam and Madera regions with co-op battles on Angel Island and the Cronkhite Bunker. For Ark Hunters looking to test their might in some competitive multiplayer action, the Freight yard and Observatory will provide opportunities to prove themselves worthy of Von Bach Industries’ recruitment.
