GSC Gameworld's S.T.A.L.K.E.R. series got a tad bit excited this morning as new gameplay footage from the IP surfaced on YouTube. As it turns out, the video is from S.T.A.L.K.E.R. Online (yes, really), which is an MMO being developed by CyberTime Systems using its proprietary BigWorld game engine.
Apparently the title has been in the works for a while, and an ongoing open beta phase is currently available in Russia. VG24/7 reports that there is a multi-language pack in the works, but until it's ready you'll need to bone up on your language skills if you want to participate.
For the uninitiated, S.T.A.L.K.E.R. is a series of post-apocalyptic single-player titles that mix first-person shooter action with sandbox RPG elements. Head past the break to check out the gameplay footage.
