Killzone mercenary gets 2 multiplayer maps

PS Vita shooter Killzone: Mercenary is getting two free new maps, according to a post on the official Killzone community page.

Here's some details on each map:
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.

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.

The update will require 167MB of free on a memory card to download it, or 526MB if previous updates have not been downloaded.
