Gears of War: Ultimate Edition is a remastered version of the original Gears of War (2006) game. It contains the full original campaign with small tweaks but a complete visual overhaul. It also has the five chapters of the later PC version. All graphics including the cut-scenes have been redone in 1080p and there are small changes to the controls. The casual difficulty settings of the game has been made more accessible, with three more difficult settings in addition. There are reworked achievements to show the progress, there is 7.1 dolby surround sound and there are comics as unlockables.
The game's multiplayer has been reworked locked at 60 FPS for smoother gameplay. Changes to the multiplayer include eight-way rolling instead of four of the original game and some traversal elements that were introduced in later games. All game modes have support for dedicated servers, a small amount of spectator options and tweaks to map balancing. New game modes are Team Death Match, King of the Hill, and the two-on-two Gnasher Execution mode designed by the community. It is also the first Xbox One game to support multiplayer games over a LAN. The game provides access to the multiplayer beta of Gears of War 4.
This most base release of the game is known as Day One Edition on Xbox Marketplace (where base game itself is treated as part of a bundle) and includes two bonus DLCs not available standalone:
Gears of War: Ultimate Edition - Civilian Anya
Gears of War: Ultimate Edition - Animated Imulsion
