For the past three weeks, PlayStation Plus and Killzone 3 owners have been testing out SOCOM 4's multiplayer. Today Zipper Interactive is opening the beta up to all PSN users.
The beta features two maps, "Port Authority" and "Assault & Battery." They can be played in the following game modes:
Suppression: SOCOM 4s version of team deathmatch.
Last Defense: Capture controls points, discover the enemy base and destroy it.
Uplink: Steal enemy data and deliver it to your base.
Bomb Squad: Defend your bomb technician while he disarms enemy explosives.
Sniper Alley (Custom): An 8 vs. 8 version of Classic Suppression with higher damage. Weapons are limited to sniper rifles, shotguns, smoke grenades and poison gas.
Last Defense Run n Gun (Custom): Faster movement speed and reduced damage are applied to 16 vs. 16 Last Defense with weapons restricted to only shotguns and SMGs.
Scrum (Custom): Suppression is given rule tweaks of no respawn, faster movement and higher damage, while sniper rifles, frag grenades, concussion grenades and poison gas are disallowed.
The non-Custom game modes can be played in either Classic or Standard setting. Standard is similar to SOCOM 4's single-player while Classic has faster movement speed, rounds, no respawns, and no health regeneration.
