Gears of War thrusts gamers into a deep and harrowing story of humankind's epic battle for survival against the Locust Horde, a nightmarish race of creatures that surface from the bowels of the planet. With Gears of War, Epic Games returns gamers to the massively scoped worlds, memorable characters, cooperative gameplay and hyper-realistic combat that gamers have come to expect from the franchise, plus a few new surprises.
Gears of War will feature locations that are unique to the franchise and the genre. Players will encounter all their favorite foes from the Xbox 360 version; however, these intense encounters will take place in some new environments and allow players to manipulate the new game modes and technology found only in the Games for Windows title. Gears of War will challenge and push the limits of the PC gaming experience and provide an unparalleled visual presentation.
- Engaging and disturbing cinematic story. Movie-like cut scenes, cinematic camera moves and in-game storytelling bring the brutal, emotionally charged narrative to life.
- Gamers control Marcus Fenix and his fire team as they pit advanced technology against the overwhelming and horrific Locust Horde.
- Unmatched online gaming. Gears of War will tap into the power of Games for Windows - LIVE to deliver online matchmaking for its Gold account members. The service will enable gamers around the world to connect via their PCs, allowing players to experience individualized matchmaking, view player statistics, earn player Achievements, customize games and create personalized profiles.
- New Game Editor. The game will also feature the all-new Game Editor, guaranteeing new user-generated content in the future. The Gears of War community will be able to tap its endless creative potential to develop an unlimited number of user-created levels through complete access to the Unreal Editor. Using the new engine, players can now import custom artwork into the engine, create particle systems, scripted encounters, cinematics and more.
- Astounding visuals in next-generation gaming. Gears of War ushers in the next generation with incredible visuals, pushing DirectX 10 visual designs and bringing out the smallest details in the largest battle. Gamers experience a rich, dynamic world with a supreme level of detail. Characters come to life with unbelievable model quality and a physics-integrated animation system that has them truly reacting intelligently to events unfolding around them.
- Hyper-realistic and intense combat. In Gears of War the battlefield is a lethal place - to foolishly stand out in the open is to invite an untimely demise. To survive, gamers must employ strategy, take cover using the interactive and dynamic environments, and suppress the enemy with blind fire, using their weapons and teammates to outwit and outfight their terrifying enemies.
