Boring is an understatement.
Right, let's get this over with. This game was a good concept ruined by terrible execution. The game world is huge, but a nightmare to navigate due to terrible mapping. You frequently get stuck miles from civilisation without a vehicle, and worst of all - the 'FPS' element is dreadful. Enemies shoot you while facing the other way, your guns are totally unsatisfying and the frustration is assured since enemies respawn behind you incredibly fast. You'll be forced to fight through some checkpoints 100+ times during the course of the game. Oh, and the destructible scenery? Lies.
Top this off with weak story without any real motivation, forgettable characters and tedious collection jobs... the best advice I can give is to go play Just Cause 2 instead. That's how sandbox games should be!
