A brave Russian mod team has challenged themselves to port the whole of GSC's survival horror, STALKER, into Crysis' more advanced engine. The project's called Cryzone - Sector 23, and is far along enough for the team to have released a video of the mod in action. You'll find the video embedded below.
The mod is the work of a team called World of Stalker. It's still a work in progress, but famous elements from the STALKER series are already in there, including the bleak landscapes, anomalies, and groups of terse Russian men sitting around campfires.
The video shows off some of the destructability and improved physics that comes with the upgrade to Cryengine 2. The mod plans to add some new features to the game, including a Far Cry 2 style healing system, in which your character must fix wounds by injecting themselves, or removing bullets from wounds. For more information on the mod, check out the Sector 23 page on the AP forums . It's a staggering undertaking, but judging from the video below, the results could be pretty spectacular.
