Picked this up used for the PS3, as I was bored and heard that Reloaded's split-screen multiplayer was better. It's nice to play the game at 60 frames, and it's awesome to see that customizable loadouts are in split-screen multiplayer.
Single player's as good as it was before, just a lot smoother now. Still don't care for the endgame boss battle or the QTE's, but it was still fun. I just wish that the Janus emblems had an actual use, maybe classic cheats like Invincibility or Infinite Ammo. Missed opportunity there.
As for online multiplayer, I can't really say anything except that it's awful. The framerate gives me flashbacks of GoldenEye on the N64, and the lag's infuriating. The maps are also crowded as hell. Should've just stuck to 4v4, honestly.
Great FPS, if you need a good single player campaign, or a nice split-screen game. I'd avoid online play in public matches, but I haven't tested smaller amounts in private matches. Hopefully, it's much better.
