Killzone 2 Review
Not that we realised they were still open but Killzone 2 and 3's multiplayer servers are shuttering in March | VG247
Finished Killzone 2 on RPCS3, now playing Killzone 3. I never got to play this one when I had my PS3. Much better and more responsive controls than 2. System Specs: Legion
