I know what you want: PAYBACK !
Personally, I was a fan of SoF2. So when I first saw SoF: Payback was released, I remembered these good memories and had the game. But that was a huge mistake!
SoF: Payback has nothing to do with SoF:2 and I am telling you this from the start: It sucks big!
Graphics: Graphics doesn't seem old, but also they are nothing special too.
Sounds: Sounds in this game, especially voice acting are like a big joke. They are terrible. Also they will make you hate this game.
Gameplay: Gameplay is also a bad joke. Ok I know, guns pushes when shoot but why I can't shoot anything properly?
You should listen your war partner in game shouting "Take that you bastards!"and sounding it like "OMG I am bored to death while recording sounds for this game, can't they make it quicker!". Whole game looks like made just to annoy people who liked SoF2. Nothing special, nothing fun, nothing good!
If you bought this game before making some investigaiton about is it good or bad, I probably know want you : PAYBACK !!!
