In Call of Duty 5: World at War the rules of engagement are completely changed and WW II gaming is redefined, thrusting players into the final tension-filled, unforgiving battles against a new ferocious enemy in the most dangerous and suspenseful action ever seen in WWII.

Call of Duty 4 Technology - Built using the Call of Duty 4: Modern Warfare engine, Call of Duty: World at War utilizes a bedrock of technology that delivers jaw-dropping visuals, while empowering players to employ elements like fire to affect the dynamics of the battlefield. Players that attempt to harness the power of new weapons, like the flamethrower, will find themselves capable of burning away environmental elements that give cover to a camouflaged enemy, leaving a charred battlefield – and their foes – in their wake

Coordinated Assault and Support - For the first time in the franchise, Call of Duty: World at War introduces co-op, bringing fresh meaning to the No One Fights Alone mantra. Call of Duty: World at War co-op features up to four-players online, or two-player local split-screen, allowing gamers to experience harrowing single-player missions together for greater camaraderie and tactical execution. The title also incorporates traditional multiplayer components such as challenges, rankings and online stats into the co-op campaign for deeper re-playability and advanced gameplay

New Theaters of Operation - Players fight as U.S. Marines and Russian soldiers facing enemies – some new to the Call of Duty franchise – that employ lethal new tactics and know no fear, no mercy, nor the rules of war. Epic conflicts are fought on multiple fronts, playing through the climactic battles of WWII in the grittiest, most chaotic and cinematically intense experience to date

Innovative Multiplayer - Multiplayer builds from the success of Call of Duty delivering a persistent online experience for more squad based interaction. New development with party systems allows an intimacy with squad based combat never before seen in Call of Duty. Combined infantry and vehicle missions add a new dimension to the online warfare and offers more PERK abilities

Cinematic Quality Graphics and Sound - Treyarch's award-winning sound department returns with effects that add to the already immersive cinematic intensity of the Call of Duty 4: Modern Warfare game engine
