Killzone 3 Multiplayer Standalone
Killzone 3's multiplayer component is now available on the PS store as a standalone game.
It has a free trial which lets you play as much as you want with a level cap and you can buy a full upgrade for about $24, or $12 if you're a Plus subscriber. Less if you're American (love that regional pricing). I think it's about $15 for them, PS Plus subs must get if for about $7.50. Aussies can get the full retail version new through ozgameshop for $25.
It's a good idea though I reckon, should help boost the size of the community.
