Saboteur was an excellent open world, sand box style game. This game was a healthy mix of GTA and Assassins Creed set in Jackboot (because they wouldn't let me use N a zi in this post) occupied France. It provided me with plenty of hours of open world style adventure. The story was compelling enough to keep the game interesting, and there are enough side missions to keep you going. Also, who doesn't like killing Jackboot Germans? My only complaint is that after the side missions and main storyline were exhausted, the Kaiser points of interest became a little redundant with little incentive to continue playing. Overall a very solid title.
This game is a lovely mix of GTA, splintercell and Call of Duty. Set in WWII, which is generally a over played genre, the world itself not only gets color but the music changes based on how heavily occupied it is with Nazis. The more missions and side missions you do the brighter the world looks. The voice acting is fairly poor and the driving mechanics are lame to say the least, but its an amazing concept. You don't always have to sneak into an area you can just go in there and BSU like a boss.
