Complete section corresponding NSM
Transfer to Area 1, then over to Area 4. Descend, and take the flares if they haven’t already been selected. Parachute into this level, then hit Start to activate the flares. Charge right and notice the spikes. Stand at the edge, then swing right over them. Then there’s three really long swings over rows of spikes. For each, go all the way to the edge before swinging. On the last swing, get ready, because there’s a crazy guy who charges you with a knife right where you land.
Kill him, go to the edge, and execute another long swing. There’s a stationary shooter behind a barrel where you land. Use the barrel sequence and kill him, and grab the bullet with the bionic arm. Then hook straight up and go into the communication door. As before, choose communicate, then cut him off. Go back out. Walk to left part of the platform and hook straight up twice. If you want to, then kill the guy behind the barrel on the right, but you don’t have to. Walk left, and kill the guy on the upper platform by hooking up if desired. If you’re good, however, you might be able to swing off the rock and hook straight up onto the platform. Either way, you’ll get onto the silver platform. There’s a mad guy with a knife you need to worry about AND a stationary shooter, so inch slowly right until you see someone, whereupon you can convert them to bullets.
Whatever you do, get to the boss door, which is at the upper right corner of this level. Here’s on way: once at the rightmost edge, swing off as far as you can. You’ll land on a very small platform. Swing right as you can again a few times, then get onto the rightmost platforms. Keep on going up, then kill the sword guy. Hook diagonally and kill the stationary shooter, then hop into the boss door.

Once you enter the boss room, you’ll see no guys. (gasp!) You’ll also notice two red life dots (gasp!) Get onto the first, long platform where the commander was on in Area 1. Keep on walking right, then swing onto the small platform right next to the generator. While in air, you’ll be greeted by the bearded soldier. You don’t really have to kill him. There are several techniques to beating the bearded soldier-guarded control rooms.
1- You can get your butt down and shoot him up, then return peacefully and destroy the generator. NSM
2- You can just ignore him and keep on shooting until he knocks you down, then get right back up onto the platform, shoot until he knocks you down, etc. NSM
3- You can let him greet you, then swing all the way to the left. The gunner will follow you. He’s slow, however. Once he’s at the left side, start swinging quickly to the right again, then shoot the generator before he can catch up. NSM
Whatever you do, you’ll receive the wide cannon, which sounds good but really is virtually useless except against convoys.
