If you thought the battle lines were clear, you've not seen the whole story. Developed by Guerilla Games Cambridge, a wholly owned subsidiary of Sony Computer Entertainment Europe, Killzone: Mercenary for PlayStation Vita, a new first-person shooter in the acclaimed Killzone series, throws players into a deadly firefight as part of a ruthless Mercenary faction, one taking on paid contracts from not only the dangerous ISA but the vicious Helghast as well. As the first handheld entry in the series to retain the console titles' first-person shooter gameplay, Mercenary promises to combine an epic single-player campaign with a substantial multiplayer offering. In Killzone: Mercenary, there is no good. There is no evil. There is only the mission... And the money.
Spanning key events of the Killzone trilogy, Killzone: Mercenary explores themes of greed, revenge and conscience against the epic canvas of full-scale military invasion. It's the story of a young boy torn between two factions desperate for victory at any cost.
