One of the most realistic shooters on the market

User Rating: 9.4 | Red Orchestra: Ostfront 41-45 PC
Red Orchestra: Ostfront 41-45 started off as a WW2 Total conversion mod for UT2k3 and then moved to UT2k4, the game also won the "Make Something Unreal" mod contest.

This game is simply beautiful in terms of weapon specs and realism. From the way you reload to firing a tank, Tripwire had definetly put time into this game.
Tanks have certain weakspots, (Try taking on a tiger tank with a T-38 russian tank and be amazed on how the shells bounce right off) and even ricochet on the MG rounds firing from the tank turrets, the MG34 and 42 and the DP28

Teamwork is practically a must since you have to cap objectives like in BF2 only the maps are about 10x larger, some with tank support.

For those looking for a realistic shooter where you rely on the skills of your comrade, I highly recommend Red Orchestra: Ostfront 41-45.
