We've just let loose with the invitation beta for Rising Storm, the upcoming next game in the Red Orchestra franchise. A bunch of people have already been sent their keys - and there will be a bunch more heading out over the next day or so, through friendly websites. If you want to watch and get ready to grab a key, check these websites:
PC Gamer
PC Games N
Gamereactor (you may have to guess which international site!)
Igromania or VG247.ru - better watch both
Mammoth/Ausgamers in Australia
Curse
A few extra will slide out through Wewana Play as well.
