So, this one kinda flew under my radar until recently.
I think it kind of looks like a mix of STALKER and Fallout 3, but opinions may vary. I'm pretty excited to see what comes of it.
Basically the human race has been forced to live in subway tunnels underground.
Apparently 4a Games (the team making it) is a bunch of people who split off from the STALKER team. Which would explain why it looks so similar.
