EA has unveiled details regarding the open beta phase for upcoming sci-fi FPS Crysis 3, with a date set for January 29th. Players wanting to jump in on the action will be able to compete in two beta multiplayer modes; Hunter and Crash Site. The open beta will also feature two maps, the dark Museum map and the open field Airport map.

Hunter Mode: This multiplayer game mode is all about the survival of the fittest. There are two teams, initially comprised of two permanently cloaked “Hunters”, and up to fourteen CELL troopers awaiting extraction. Each trooper slain respawns on the Hunter team to prey on their former allies, building to a frenetic climax. If any of the troopers survive the round, the hunters lose. Whichever way you play, Hunter Mode delivers a heart-pounding test of strategy and survival.

Crash Site Mode: This multiplayer game mode is the ultimate King of the Hill type experience. An Alien dropship deploys a pod at random around the map. Players on each team must remain near the dropped pod in order to capture the zone and accumulate points. Each alien pod holds two shields players can utilize defensively as weapons. In addition, each Crash Site map will have a “Pinger”, a CEPH-constructed walking weapon of mass destruction. But be careful, other players can hijack the Pinger while you’re inside of it!

The open beta will allow players to level up to rank 10 before capping out, and will offer various customisations for your Nanosuit including weapons, attachments and suit modules. The open beta will begin January 29th, and will be available for PC, PlayStation 3 and Xbox 360.

EA has also revealed a new gameplay trailer titled 'The Nanosuit', detailing just what exactly players can do with their exo-skeleton suit. Check it out below.
