I'll start by saying that I am a huge fan of both video games and World War 2 related entertainment. What I am not, is a professional critic. This is based on my opinions, and gaming knowledge I've learned from experience, G4, and gaming magazines. Now, on to the review.
This has got to be one of, if not the best World War 2 video game I've ever played. While Call of Duty and Medal of Honor are awesome in their own rights, it doesn't have what BiA has: tactics. Real tactics and squad commands. It's also the most historically accurate game I've ever played (other than problems regarding German forces.) You actually have to use your squad to win, which is something I've never seen in a WW2 game. BiA is best described as "Band of Brothers: The Video Game". And since BoB is the highest rated mini-series on IMDb, that's a good thing. It's fun, addicting, and as close to Operation Chicago as you're ever gonna get. Best of all: your squad mates aren't idiots who run into gunfire. They'll take cover, flank, and be avoid enemy fire when you order them to move.
Now for the bad side. The worst thing is the enemy A.I. The German infantry in this game is about as smart as a rock. They'll take cover, then shoot at you. That's it. They won't move when your flanking maneuvers are detected. They don't try to flank or out-flank you. They don't try to run for it, or get to a better position. They stand there and shoot. Also, the German artillery positions aren't camouflaged, something that any army is especially sure to do. In an attempt to be as realistic as possible, Gearbox designed your rifle to move slightly while aiming, just like real life. While not necessarily a game-killer, it's still pretty annoying. Picking up weapons in the middle of a firefight is pretty rage inducing, though.
Final verdict: an awesome game well worth the price (purchase or rental), but not without its faults. 9/10.
