About Underground 2
After making your way through the darkness, you discover some old service tunnels, long ago drenched in water, and neglected. There are signs of military use, missiles and warheads, that come as a shock to be found down here, this facility is more serious than you first thought. The railway lockdown is making your journey through the facility even harder, as you must find other routes to get back to the track; it may hold your only key to freedom.
