Big MT east tunnel
If you see the tunnels with the trains plowed into them, you can thank our visitor for that. He wrecked the whole place.”— Doctor 0
Big MT east tunnel is a location in the east of the Big MT.
This area appears to be a tunnel blocked by several crashed red train cars. You can run up the hill on the right of the tunnel entrance and get on top of the tunnel, then jump to the train carts one by one. There are several chems in a duffle bag on top of the tunnel.
