The free trial will come on the heels of Red Orchestra's soon to be released Free Booster Pack. The original game features 13 maps, 28 weapons and 14 crewable vehicles. Just 4 months after release, the Free Booster Pack and previous updates add a large number of new features including: - A full new map, Lyes Krovy, a brutal close-quarters fight for a German trench-and-bunker position in a forest in northern Russia in the summer of 1944. Soviet forces attack a strongly-fortified position, while the Germans fight hard to hold them off. Lyes Krovy has rapidly become a favourite with the Tripwire test team!

- A new weapon system - smoke grenades. On select maps, infantry commanders will now have smoke instead of explosive grenades, which can be used to create quick cover for assault routes, or to momentarily blind the defenders. We're finding that clever use of smoke can change tactical stalemates at a stroke! - Two new weapons - the German MP41 sub-machine gun and the Soviet M44 rifle.

- Numerous other changes to the tank armour penetration systems; the tank reloading system and changes to the victory conditions to prevent stalemates.
