Red Orchestra: Ostfront 41-45 finally invades Mac today, over seven years after it stormed Windows and Linux. Tripwire Interactive's tactical first-person shooter was developed from Red Orchestra: Combined Arms, which itself is a conversion mod of Unreal Tournament 2004. Meanwhile, sitting next to the Mac attack is a tempting deal for the game's follow-up.

Not only is 2011's Red Orchestra 2: Heroes of Stalingrad free on Steam this weekend, but permanent capture of the game will endure 85 percent less wallet-based casualties than normal, with the game down from $19.99 to just $2.99. The 85 percent deal also applies across the Red Orchestra franchise deal, which includes Ostfront 41-45, RO2 and its deluxe upgrade. However, since RO2 isn't out for Mac yet, it only applies to Windows users - give it another five or so years, Mac.
