We've already seen the formation of Vostok Games after the break-up of S.T.A.L.K.E.R. developer GSC, but it looks like another company is emerging from the stricken studio's ashes.
Luckily, some handy information backs these claims up. Union Studio's LinkedIn page describes a "new company, created together with the best professionals that worked for GSC GAME WORLD and other AAA class studios." The page announces the team are working on a "cross-platform action shooter which will be available for PC, Mac, PlayStation, XBOX."
Former GSC team leader and software developer Eugene Kim has listed himself as the new CEO & Founder at Union Studio in the Ukraine. A website is also under construction.
Perhaps the team is to work on something similar to Vostok Games' free-to-play Survarium, but at this moment in time, any other details are scarce.
