It looks as though Vostock Games might not be the only studio to form in the aftermath of the break up of STALKER developers, GSC . Russian gaming site, StopGame reports that a significant element of the GSC STALKER team have set up shop in Kiev, and have formed a new outfit called Union Studio.
There are a few tidbits to back this up. A description on UnionStudio's sparse LinkedIn page describes the developer as a "new company, created together with the best professionals that worked for GSC GAME WORLD and other AAA class studios." The page announces that they're making a "cross-platform action shooter which will be available for PC, Mac, PlayStation, XBOX." There's also a work-in-progress Union Studio site , which simply says "coming soon."
The LinkedIn page of former GSC team lead and software developer Eugene Kim now has him listed as the new CEO & Founder at UnionStudio in the Ukraine. Kim's Google+ feed is topped by a link to StopGame's "another shooter from the developers of STALKER" story. StopGame claim that the game will be announced this Autumn and have a futuristic setting.
The developers haven't officially announced anything yet, but we could end up with another ex-GSC effort to look forward to alongside Vostock's free to play MMO, Survarium .
