While worth playing, the latest in the Wolfenstein line of games fails to bring anything truely unique to the table.
Throughout the single player campaign, you obtain money for completing missions, and by picking up gold scattered throughout the world. You use this money to purchase ammo, and crucial upgrades for your weapons and veil powers. By upgrading your weapons, you also change how they look by adding the new attachments, as well as obviously giving them a boost of performance. (Almost reminiscent of Bioshock) Also, as if not game breaking enough, you can purchase upgrades for your veil powers, such as the ability to reflect bullets with your shield, or shoot through solid objects with empower.
On the topic of B.J.'s veil powers, I will say that they are quite fun to use. It can be very satisfying to throw on a shield and take out large groups of enemies with your Tesla gun, but at times it can make the game play feel a little dull, and too easy.
My biggest problem was just that, the game was incredibly easy, especially for Uber mode. Overall, it took me just over 6 hours played time to beat the entire game on Uber. The Nazis also really aren't very intelligent considering they even found out how to access the veil, since when a grenade is thrown, they pretty much just yell "Grenade!" and stay put. Also, for the most part, your weapons are so devastating when upgraded and paired with veil powers, that boss fights can end very quickly, which doesn't make victory very rewarding. Two bosses however are exceptions to this; the Geist Queen and Hans, which will likely give you a bit more trouble. Unfortunately though, the final boss fight with Hans is more so painful and tedious than challenging, however it's just as rewarding once you do finally take him down.
The graphics in Wolfenstein aren't bad, but there is a noticeable lack of color, which does make the player feel like they are in a war, which in my opinion, makes the lack of color not necessarily a bad thing. The head-bobbing when you run feels a little awkward, but for the most part, everything is animated pretty well.
Unfortunately, the online aspect of Wolfenstein has not worked as of yet for me, so I can't comment on that, however with no official review out of Wolfenstein yet, take my advice on the game. Overall, it's worth playing, at least renting.
