Jurassic Park Part 2: The Chaos Continues/Blockade

This level's a real maze if you don't know where to go. You can keep your machine gun equipped if you like, but if you keep spraying bullets, you'll run out of ammo. If so, your rifle will do fine anyway. Start by going to the right and enter the door. Continue right, shooting the enemies in your way, and watch out for the flamethrower at the top of the ramp. Get rid of him by standing at a distance and jumping while shooting. You can use the shotgun to make it a bit easier, but don't use the shotgun too much in this level because you'll need a good amount of shotgun ammo at the end. Continue right as before. You'll come across a flamethrower on the walkway above. Take him out from below. Jump over the gap, go up the ladder, and progress to the left. Again you'll see a flamethrower above who should be taken out from below. Continue left, climb the ladder, and progress right. Be careful, there's a bazooka at the end, so duck and shoot it. Go up the ladder. You will see some platforms to the upper-left, and each one has a bazooka firing at the ladder. Hit them diagonally from below. After you dispatch the third and final bazooka, you may optionally jump on the platform and run to the left; there's an ammo pickup at the end. If you want to use the machine gun until the end of the level, you'll need it. You might instead get some ammo for your shotgun if you want to use it a lot. You could also just skip it entirely and use the rifle when your machine gun runs out of ammo. Go up the ladder and again you'll find a platform to the upper-left, this time with three gunmen on it. You can take out a couple of them diagonally from below, then jump on the platform and quickly kill the third one. Be careful that you're not too far up the ladder when you try to jump on the platform, or you'll hit your head on the ceiling, miss the platform, and probably suffer some damage when you land. Go up the ladder and jump to the right. Be careful, there's a grenadier on the left hurling grenades at that spot. Kill the gunman on the right and go through the sliding door.

Here you'll be confronted by some enemies running at you. Jump over them and their bullets. Go up the slope, and be careful, there's a broken pipe shooting some steam near the end. For whatever reason, steam is as harmful to you as flames from a flamethrower, but it is easy to pass if you just time it right. You'll see two ladders. Go down the right one, but don't take it all the way down, because there's a gunman at the bottom. Jump over to the left when you can see a pipe to jump onto. Continue left, and be wary of the steam near the pit. Jump on the railing, cross the pit, and when you land you'll see another broken pipe with steam, this one shooting it diagonally. Pass it as normal. Now equip the shotgun. Walk until you come across a bazooka. Duck and kill him with a couple of shots, and then an armored guard in blue will run up and shoot at you. Dispatch him with three or so shotgun blasts and switch back to the machine gun. Continue left and through the door.

This is the last room in the mission, but it's a long one. Ignore the next door and climb the ladder. Jump over to the other ladder when you can reach it and continue to climb up. You'll see a very large fan. Repeatedly shoot it to blow it up. Some fans, like this one, will blow you away, while others will suck you in towards the fan. Not far behind the fan you'll find two bazookas. Take them out and climb the left ladder. This next fan will suck you in, but it's not hard to avoid. Destroy it, jump over it, but quickly jump back, because there's a flamethrower coming for you. Stand at a distance and kill him. Move up the next ladder, move right, then jump on the left ladder. Destroy the fan while still on the ladder and jump up to the platform. You'll see an armored blue guard running back and forth on the other side of the fan's base. He will attack you if you jump onto the fan's base, but will keep running harmlessly if you stay on the other side. Take him out and then cross. Go up the ladder, head right, and destroy another fan that sucks you in. This time there will be a few stationary gunmen behind it. Take 'em all down, climb the ladder, and kill a few more gunmen as you head to the right. Jump on the ladder and go down. Ignore the first passageway you pass. The second will have a fan blocking it. Destroy it, take the ammo behind it for your shotgun, then switch back to the machine gun (or rifle if you're out of ammo) and jump back on the right-hand ladder. Go down to the bottom (beware of a stationary gunman, but he's not a serious threat), then go down one of the ladders to the left. There will be a fan to the left and one to the right, but they'll cancel each other out so you won't be sucked in either direction until you destroy one. Stand close to the one on the left and destroy it. Jump over its base, take the medkit, switch to the shotgun, and descend down the right-hand ladder.

The area you reach at the bottom is where the boss is. To your right on the same platform as you is a blue armored guard. Take him out with about three shots. Below you to your left is the boss! You definitely need the shotgun and a few shells to stand a good chance against him. The machine gun takes too long to kill him, and you wouldn't even want to try it with the rifle.

This is going to take away some health, since this guy's got a flamethrower and he'll probably hit you with it. Move to the right ahead of him and drop down to his level (Down+B). It may take a couple of tries to get it right. Fire at him as he approaches, but move right when he gets too close. If he's not moving much and not firing, keep blasting him, but move as soon as he approaches or shoots. If you're too far to the right, jump on the platform above, run over to the left a bit (jumping over any flames), drop down when you can, and repeat. It actually doesn't take a whole lot of shotgun shells to take him out, but it may take enough for your heart to race. Don't be too close to him when he dies, because his flamethrower pack explodes. If it misses you, or you survive the blast, you have beaten the mission.

There's also a much cheaper way to defeat him. It requires some health, but since there was a medkit before you dropped down, you'll probably do fine. After you kill the armored guard, move right on top of the boss while you're on the platform above him, then drop down so you're concealed behind him. Like most human enemies, he can't hurt you on contact, only by weapons. He will shoot his flamethrower, which won't hurt you when you're right behind him. You'll notice that he fires flames in a rhythmic pattern. Wait until he stops, run out a bit to the right, then quickly run back in while firing the shotgun. (Don't run to the left because he will fire bullets when you run to the left, but not to the right.) Repeat until you defeat him. The explosion will probably damage you (it's tough to avoid unless you know when he's going to die), which is why you need a healthy life bar. With some practice you can probably recognize his death animation quickly enough to avoid the damage, but if you can do that, it's probably just as easy and maybe a bit faster to kill him the proper way.
