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 Alpha test that started on April 21, 2015 in Russia only. On December 28, 2015, a closed Beta test was suspended.

Development
Halo Online is powered by a highly modified version of the Halo 3 engine and optimized for smooth performance on lower-end PCs. On December 28, 2015, a closed Beta test was suspended. The developers said that they encountered serious problems during the development of Halo Online, and with 343 Industries' council they decided to suspend testing and "send the game to a serious revision" for several months. Because of that, for people who bought the exclusive premuim Beta tester kits, there was a compensation offer.

Synopsis
Halo Online takes place shortly after the events of Halo 3 around January 28th 2555. The game is set on a secret UNSC space installation called Anvil, where SPARTAN-IV and Sangheili soldiers train together in simulated 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. 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 customize their loadouts, including armor, weapons and abilities. There are several variants of each weapon available for modification. Each weapon features variants with increased damage, accuracy, and rate of fire. Unlike most of Halo games, players will not be able to change their armor pieces individually, only as a whole set.

Similar to Halo 5: Guardians there is an ending animation for a match. Though in Halo Online it features only the top three players rather than the entire team.
