Love Swat4, love zombie games, love RTS's... what's not to like?
This game sounded TOO ambitious though. It probably would have sounded a lot better than it actually would be, cos that is probably WAAAY too much stuff to include in a FPS built for mainly indoor environments and enclosed spaces.
Still, it will be mourned. Rest in peace Division 9, a life unlived, taken from us too soon...
(as a side note, would be hilariously ironic if it was brought back to life by another studio... the world's first zombie-zombie game!)
