Tom Clancy's Rainbow Six: Lockdown is a squad-based tactical military FPS (First Person Shooter). The game takes place in multiple locales from Paris to South Africa as the Rainbow team tracks an international group of terrorists. The controls match that of a standard PC Shooter with the addition of context-based squad commands and actions. The PC version tries to maintain the action-oriented feel of the console version while improving on all aspects that predominate the PC FPS genre.
The PC version offers several improvements over the console versions. In addition to added classic maps like Mint and 747 there are additional kit items, added multiplayer modes, updated graphics on all maps, added HDR effects, re-ordered campaign list, updated weapons and AI improvements.
