Crytek has just announced Homefront: The Revolution as a new first-person shooter game that will feature native Linux support with the CryENGINE and launch on the same-day as for other platforms.
Crytek explains this "Homefront: The Revolution" free-roam FPS game as:
Four years into the brutal military occupation, America is on its knees. Philadelphia - once the birthplace of Independence - has become a ghetto, where surveillance drones and armoured patrols keep the population at heel, crushing any dissent with savage force. Her once-proud citizens live in a police state, forced to collaborate just to survive, their dreams of freedom long since extinguished.
The Steam developers usually make a number of intermediary releases before a stable and a large version of the application are launched. The current update is just one of these versions and, even if it's a Beta, some users might notice improvements.
Valve takes its time when it comes to improving the Steam client and its updates take care of just a few things. This way, it is easy to spot a problem if something goes wrong after an update for the software.
GOG.com is a digital distribution platform that is specialized mostly in old games, but the company that owns it, CD Projekt Red, wants to also extend the support to include Linux. They are now looking for people to help them with Linux ports, although it seems that some of them will be distributed in Wine wrappers.
