The free-to-play MMOFPS Survarium has recently released new screenshots and a second developer diary. Vostok Games is behind the free MMO and has developers from the S.T.A.L.K.E.R. series on the team.
Survarium is set in a futuristic apocalypse where Earth was almost destroyed by its own vegetation…sounds like The Happening doesn’t it? This is an online game and there is no single-player mode. Survarium is to be released at the end of 2013 on PC.
