I remember this level. You could pick up a sniper rifle off the guy on the watchtower, that red rifle with the weird ass looking scope. Then you could pick off one of the guys patrolling near the entrance or halfway inside the tunnel lol. I remember when you'd shoot an enemy in the ass he'd jump up and grab his ass lol. Still remember the sounds they'd make when they'd get shot. I miss this game...
Going old-school...
