Walkthrough: Columbia

Listen to the briefing on the Helicopter and prepare to have fun.

Walk up to the captain standing outside the tent. He will brief you more before meeting the wrong end of a sniper rifle. Now head into the tent and pick up some more ammo and any health/armor you need. After that you should move to the other side of the camp (away from the helicopter and over the flipped over truck) and into the jungle. Kill the 5 people waiting for you around the corners and proceed forward to exit. (You will pick up a shotgun and an AK47)

Walk forward and into the ruins. To the right of the first doorway is a guard waiting (lean and kill him) and this will cause to other guards to come through right in front of you, for an easy ambush. Now go forward and lean around the corner to take out another sniper standing there waiting to shoot you. Get his rifle and then head back the way you came, but head around the left side of the ruins. Proceed forward past more ruins and guards. When you come to a place with creates far in the distance, it's time to pull out the sniper rifle and kill the guards there (this is also a good place to save because of the guard with a mounted gun). When you start to see a bunker on the left hand side of the screen, try sniping the guard manning the mounted gun inside there before he sees you. Now proceed forwards walking on a cliff side until you come to a 3 way intersection. If you go left and back it will take you a the bunker with armor and some ammo. If you don't need these keep going forwards. Fight your way until you see 2 buildings, where you will have to go to your left. There is a sniper on the left side of this trail about one half the way down. After killing him, climb up the ladder to his spot and sniper the 3 guards by the temple. Proceed down to the temple. If you go up the stairs there is 1 guard up here, if not go around to the left side (through the broken wall) and then head through the doorway to the right (killing the guards in there), there is a large armor and health in here, then proceed onward. Work your way forward and exit.

Proceed forward with caution, after working past the double wall (and the guards there) you will see a big rock in the distance. Walk up to this and use it as cover from the helicopter as you disarm the trap that's next to the tree. Work your way up to the cave and kill everyone inside. Watch out for the helicopters gun fire when exiting the cave, head towards the sniper tower and defuse the bomb right next to the big rock. Kill all the guards and proceed onwards. Stay near the broken wall and snipe the person in the next guard tower, and the guys by the little hut. Proceed forward and take out the 6 guys the helicopter drops on the other side of the bridge. After that continue forwards until you see a tent. Try to snipe as many guards as you can before going on. Work your way around the tent and kill the guards inside. There is more ammo, health and an armor inside the tent. Proceed onward past the double broken wall and up a small hill to a bunker (Obj updated) Now go inside the bunker and climb the ladder to the top. Turn to your right and hit USE on the panel that says fire. Watch as the Helicopter is destroyed by their own missile. Then hit fire 2 more times on the panel. After the third time run down the ladder and out/away from the building. Watch as the missile destroys the bunker you where in and the building in front of it. Go into the new hole in the building and activate the gate. Walk through it to end the level.

Walk forward and hang to the left. Watch out for tripwires and guards. In the bunker on top of the hill is a health pack and there is an armor/health pack inside the hut on the far side. Proceed forward to meet up with Bravo Team. Once the enemy on the side of the bridge is destroyed the team leader will talk to you. Have fun watching the bridge go bye bye, and then follow the marines. They do a good job showing you how to work as a team for when your in multiplayer ^_^ If you get too far ahead or behind the team leader he will kill you for disobeying orders. Now follow Bravo team to show you where to go, and assist them as they need it. Once you get past another 2 guard towers all you have to do is walk forward and exit the level. If the Bravo team just stops moving, try going a little ahead of them then going back to get them going again.

Work your way into the rebel encampment. The Bravo team will take out most of the bad guys, but you can help when you have clear shots. Remember not to run ahead of the team. Once you get up to the middle of the village Petterson will tell you to go in and clear out the building. He's talking about the one with the steps and a double porch. Go in through the front door and clear out all the enemy's. The shotgun works great for these close battles. After killing all the guards (7 or 8) walk over to the table and you will say something about the attack. Then exit the building. Head to the building across the way where Petterson will again tell you to clear it out. Isn't he nice? Sometime the bravo team will get stuck on their paths. Try to tell where they are going and then stand in the opposite direction, this will force them to walk towards where they should be. There is armor and health in here, once you get to the top of the building, exit through the door up there. Next you have to search the warehouse. Kill the 4-5 guards in here and if you need it take the armor/health up top, otherwise exit the building. You then need to pick the locks on the cell (there's explosives there) and then walk over to the gate and again use the USE key to plant explosives on it and get away while it blows up. Then exit through the gate to beat the level.

Follow the Recon team to the extraction point. The marines will kill most of the enemy's, but you might as well help them along. Follow the team over the river and through the woods to get to the helicopter. Just in case you need to know you go along the river, through some ruins, loop up around behind the waterfall and to the coppers. After you get to the helicopters, you have to man the M60 and take out the guards coming up the trail you just came up until you take off (about 1 min)

Whoo hoo another rail-shooter level!!! This one is a lot harder. It's been asked a lot about on the boards, so I will try to explain each step of the way for this one. Remember you only have around 5000 rounds of ammo.

First off there are 3 buildings. Nail all 7 barrels around the camp to create as much damage as you can and shoot the guys as they come out of the 3 buildings. After about 1 min you wont' see anymore guys and you will continue on to the next camp. Second camp: This is the most deadly one is the most deadly one on most difficulties. The first building you approach has a gun emplacement on the upper level. Either shoot out the gunner, or aim for the barrels beside the building to do the most damage, once you circle around behind the building, there are some more barrels that will take it out for good. After taking out the main building, you will continue onwards. Third Camp: On the way to the third camp, on the right side is a tower, take out the barrels under it to keep going. This isn't really a camp… it's a bridge, take out the barrels on it and the truck to totally destroy it and move on. Forth Camp: There is a helicopter on the ground, shoot at the building and the barrels will explode, then take out the boat (just keep firing at it) and your home free.

Walk straight forward to the truck and go up the stairs into it. Talk with Taylor and put on a suit. Now you get to follow her around and learn more about the plot.
