Guerrilla er i godt humør, og meddeler at de ved midnat udsender to nye multiplayer-baner til Killzone: Mercenary kvit og frit, Blood Gracht og Tharsis Depot. Begge bygger på favoritter fra Killzone 2, og fylder 167 megabyte på dit memorykort. Opdateringen er obligatorisk for alle, der spiller multiplayer i spillet.
Guerrilla beskriver selv banerne således:
Blood Gracht
Months after the nuclear blast that ruined most of the city, Pyrrhus is slowly recovering. But now with ISA, Helghast and mercenary troops clashing in the suburb's buildings and winding alleyways, the canals once again run red with blood. This fan-favourite multiplayer map from Killzone 2 is ideal for all game modes.
Tharsis Depot
After incurring damage during the ISA invasion of Helghan, this subterranean mining platform has been converted to process nuclear Petrusite. Now that it's back in full-scale production, the ISA will again battle Helghast and mercenary forces between the structures of Tharsis Depot. This time they intend to finish the job they started. Under the cavern's artificial light this is a great map to play Guerrilla Warfare or Warzone on. A Mercenary version of the Killzone 2 classic.
