Summary: Game launched with many performance issues. Many players had computer crashes and game play suffered. There is a patch promised and this may improve things. This is not a game for a player new to first person shooters as a veteran player will kill you very, very, quickly. This can take the fun out of the game until you learn the very steep learning curve. Not for beginners!
Summary: These comments are general and mostly about the single player game. There are some good things about this game; The graphics are good and representation of real structures is historically accurate. Much of the conflict is at longer, more realistic ranges. The weapons and their sounds are quite authentic. If you get shot, you'll likely die and have to re-spawn. No hide and heal. Here are the problems in my opinion. 1. Very buggy. Freezes and drops me into Windows.
Summary: This game is a more realistic shooter in the sense that a bullet or 2 kills you. No getting shot up and taking a breather. This is something I like, you have to be careful and use strategy to defeat your opponent. Huge maps and you can go inside and explore almost all structures. Descent selection of period piece weaponry. Nice optional gore. Single player controllable squad. Now the unfortunate parts, the graphics are really dated.
Summary: Be careful, weed out the sycophantic "fanbois" pseudo "reviews" here and everywhere else. This game is a dog with fleas. One of the worst releases of the year easily. Unless you are an RO / OSTFRONT fanatic, and/or a WWII semi-realism fanatic and a buggy, broken, old looking game does not bother you, avoid this for now.
Conclusion: Like many others I've been waiting ages for a decent WWII shooter and unfortunately this just isn't good enough. The original Red Orchestra went for a realism-oriented approach but RO2 seems stuck between sticking with that or trying to attract arcade/action-oriented players used to games like CoD; by not concentrating on one or the other it fails at both.
