Red Orchestra 2: Heroes of Stalingrad
If AAA titles are out of your budget, worth a look
From the relatively unknown TWI comes a WWII shooter, focusing on realism and team play. A bit of a niche product, wedged between behemoths like COD and Battlefield on one side, featuring the most popular game-play style, and games like ARMA on the other side that feature near military SIM realism, this game will appeal greatly only to some players.
Don't expect AAA level graphics, animation or story, or much of a single player at all, enjoy team-based play, and you may enjoy the game. Those looking for maximum realism will be better served by games like ARMA (available at EB), and of course the upcoming COD and Battlefield titles will likely be more appropriate and more enjoyable choices for mainstream PC gamers.
Bottom line: if you want something different, and a game from a small studio lacking the polish of AAA titles does not bother you, this game may be worth a look, particularly if you are a WWII centric PC gamer on a limited budget.
