Red Faction II is not worthy of it's title.
The story is not in any visible way related to the rest of the Red Faction series, so if you don't play, you're not missing anything.
The gameplay seems much more oriented to just destroying and killing enemies without purpose, compared to the first game where there is clear direction, and where stealth may be a key tactic.
The control system works well with a keyboard/mouse setup.
The graphics, somehow, seem worse than in the original game, even though it was made later. Things seem more blocky, as well.
The voicing in this game seems to make use mostly of generic "shoot-em-up" lines, and isn't very interesting. This is slightly redeemed by the fact that Jason Statham voice acts in this.
The installation works fine on windows 8.1, no issues as compared to the first game. Check the forums for a guide if you do have issues, though.
Don't buy this game. It doesn't play a part in the wider Red Faction story, and it's poorly made.
