Developed by a team of former GSC World members, Survarium will eventually contain an open world 'FreePlay' PVE mode in the style of the S.T.A.L.K.E.R: Shadow of Chernobyl solo campaign, in which you'll be able to team up to take on hordes of mutant creatures and scrabble around for ration packs in the radioactive mud.
