The “Tom Clancy’s Rainbow Six” series began in 1998 as a Windows PC game developed by Red Storm Entertainment, called “Tom Clancy’s Rainbow Six,” loosely based on a then incomplete book called Rainbow Six by Tom Clancy. Stop me if I’m going too fast. In an time where games like Quake 2 and Half-Life had you shooting aliens, robots and rooms full of explosive barrels; Rainbow Six offered something different: realism, planning, strategy, and teamwork. These key elements were passed down, unscathed and in some cases improved, to the two sequels that followed: Tom Clancy’s Rainbow Six 2: Rogue Spear and Tom Clancy’s Rainbow Six 3: Raven Shield (seriously who comes up with these ridiculously long names). All seemed good for the series until. . . . Tom Clancy’s Rainbow Six: Lockdown.
