It's already been two days since Rainbow Six Siege, the multiplayer version of Ubisoft's long-running tactical shooter series, began its free week. The free week runs through Thursday, March 21, and you can keep the game for just $4 (85% off) through Wednesday. [But according to PCG's multiplayer FPS expert Morgan Park, "Siege" is better than ever.
