Halo Online

Halo Online is an upcoming multiplayer-focused game, developed by Saber Interactive and Innova Systems in collaboration with 343 Industries. It was officially announced in March 25, 2015, with a closed beta test starting in spring in Russia only.

Development
Halo Online is powered by a highly modified version of the Halo 3 engine and optimized for smooth performance on lower-end PCs.

Synopsis
Halo Online takes place shortly after the events of Halo 3. The game is set on a secret UNSC space installation called Anvil, where SPARTAN-IV soldiers train together in war exercises to sharpen their battle skills and test experimental technology.

Gameplay
Halo Online will include "classic weapons and vehicles" from the Halo franchise, including the Hornet and the energy sword. Several new weapons will also be implemented into the game, including an unidentified submachine gun. Fan favorite multiplayer maps will return, along with several new maps—one of which is set in a Russian town. Halo Online is optimized for keyboard and mouse controls. Online matches can currently handle up to sixteen players, with four players being required for a match.

Players will be able to heavily customize their armor and weapons. There is several variants of each weapon available for modification. For example, the battle rifle features variants with increased damage, accuracy, and rate of fire.
