Homeworld: Remastered Collection is a remastered release of two space real-time strategies, Homeworld and Homeworld 2. It includes three executables - one for each campaign, and one for a new unified multiplayer system which allows access to classic games' deathmatch modes and a completely new mode which combines the races from both titles. Other changes include high resolution support and overhauled user interface, higher-fidelity graphics with numerous new settings, recreated cinematics with contributions by original artists, new audio mixing, and Steam Workshop support.
The original versions of the games are also included, but with disabled multiplayer capabilities. Homeworld: Cataclysm content is not included in any way.
