Red Orchestra is a fantastic fps that simulates combat in WWII on the eastern front. I’ve written about it a couple of times before. Though I don’t play much anymore it’s still my current fave fps. They recently released a major engine and content update (more players per match, new maps, etc) and to celebrate they gave all players 2 free passes they can give to friends so their friends can try the game. First 2 folks to say the word get a free pass from me. Not sure how long it lasts, probably at least a couple of days, certainly long enough to get a feel for the game, and it’s cheap enough to buy if you end up liking it. Post in the comments to get your pass.
