Jurassic Park Part 2: The Chaos Continues/Seek and Destroy

Like Raptor Attack, this mission is fairly easy (although not as easy), though it's much easier to get lost, and at the end you'll have a dramatic climax where you must quickly escape or die. Also, a triceratops can be found in this level! (You don't have to fight it, and in our walkthrough, we won't.) Keep the cattle prod equipped throughout most of this mission.

You start just outside the volcano. Progress right. You'll encounter a grey raptor, shortly followed by another. It's pretty easy to just jump over one, then the other, if you don't stop and just keep going right. They'll stay far enough behind that you won't have to kill them. If you don't think you can do this, go ahead and fight them one at a time. After the two raptors you'll go into the volcano.

Inside the volcano, you'll encounter a lot of pterodactyls. These are ten times as annoying as compies, since they pursue you deliberately. One uncharged shot of the cattle prod will take them down (two on hard mode). Go past the first door and go into the second. You'll see a green raptor below you. Kill it, progress left, and go into the door.

(rest of walkthrough to be written)

After planting the bomb, equip the shotgun and progress to the right. It will go off not long after it's off the left side of the screen. You will encounter a few velociraptors. Don't worry, all the raptors you encounter now will be green ones which will die in one blast. You will encounter a gap, which you must jump over, then, almost immediately, another one. After that, there will be no more jumps and you can concentrate on just shooting the raptors as soon as they appear. As soon as you see the door, go into it, and you have completed the mission.
