Killzone: Mercenary will release a week sooner than previously announced. The PS Vita shooter circle strafed from September 17 to September 10 (or September 6 in the U.K.), Sony revealed on its PlayStation Blog today.
That's the kind of release date change we like to hear about, but why would Sony bother? It didn't say, but GTA 5 coming out on the old date may have had something to do with it.
If you want to castrate some Helghast on the go before losing yourself in Los Santos, pre-order bonuses include a multiplayer XP boost, extra single-player starting cash, and an exclusive machine gun for both modes.
