How do you get underground?

Most likely hackers and/or glitch

Looks like it's a glitch or something

It's hard to explain but there are videos on youtube for it. Go over to the cliff part where the water fall is. There is a big rock just outside. There is a crease in the rock you have to jump into tht. I've done it once. But it is very hard to get perfectly. I usually get shot doing it.

Ok so if you have like a mg42 or some heavy gun, it's a lot easier. The flamethrower is the best, though. What you do is you go over to the side of the map a clifside where the is the big den-like thing and waterfalls. On the side of it where there's that thing with bars is where you should go. Fo down the hill and there's a small ledge with spike sticking out of it. Then there's a big rock. In the rock, there are 2 creases. If you stand close, you can see the one on the right. That is the one you should use. Line up facing it and back up. Run and jump towards it. If you land on top of the rock just start over. Try to get just in front of it. After that first jump, then just ress forward and keep jumping until you go inside and see blue. When you're there, you can walk around pretty much the whole map, but if you go in the back part by the cliff, you will fall off. Some parts have water that you can fall into. Just keep going and you'll get back up. The water won't kill u. Hope this help. If you can't understand this explanation very well, then here is a link on youtube for the video........

Dont do it. Good players are getting tired of playing with ppl who, suck so bad they, have to cheat. Hackers, glitchers, doesnt matter they all suck. Cheating is the 1st sign of an admitted looser who doesnt strive to be much more than worthless.
