The massive expansion is totally free to UT3 players.
Posting on the official PlayStation Blog, Steve Polge, lead designer on Unreal Tournament 3, has confirmed that the Unreal Tournament 3 Titan Pack expansion will be released on the PlayStation Store today.
Earlier this month the PS3 version of the expansion was delayed because of a longer than expected certification process.
The expansion includes the gametypes Greed and Betrayal, the Titan mutator, 19 maps, the Link Station and X-Ray Field deployables, the Stinger Turret and Eradicator Cannon weapons, the Stealthbender vehicle, the Slow Field power-up, and characters Kana and Nova.
