Aliens versus Predator 2/New Target

Map 1
Leap to the corridor above. Follow it until you drop into a small room with a few lockers. You won't find anything interesting inside, all doors are locked, so climb the ladder down. Two humans won't be a problem since one of them is harmless and both are distracted. After they are killed, open the door and drop down. There find a circuit and hack it to open the door you've seen before.

Head back, jump up and to the door where you've previously killed two humans. Behind the door you will first meet a soldier face to face. Beside him there are also three soldiers, two of them with heavy guns. The area you're in is big but not big enough to get lost. There are two ways to reach the next stage:
 * Look for a few big crates. Open the hatch and drop down. You can search the place for some ammo, then follow the only way you will find there.
 * Look for locked double doors. Use the lever nearby to open them and head inside.

No matter which way you took you will appear in a big room of unknown purpose. Now a really hard part begins. Soldiers won't be of much trouble, but the room is infested with turrets. As you know, you can't highlight them with any of your special visions nor can you hide from them using your cloak. Some of the turrets are hidden or high spots difficult to reach and between crates difficult to spot. Luckily, all the turrets have blind spots.

After you've secured the area, look for an open door between crates. Use the elevator and you will come to a control room. Behead two scientists and use the lever near the big "cargo crane emergency release" sign which is near the window.

Note: Before heading outside look at the skirmish with all the vision modes you have. From now on you will be able to meet both humans and aliens in the same room. Choose wisely which mode to use. Highlighting some enemies mean hiding others.

Head out and kill all remaining foes. Most likely, they will be humans. Jump down and look for a hatch nearby. It will open by itself when you come too close. Jump down and that's it!

Map 2
After a few steps you will appear in a huge flooded tunnel. Pretty soon you will be attacked by three aliens. Follow the tunnel and you will come to a fence. Leap over it. Soon you will be attacked by another pack of aliens.

Continue walking down the tunnel. Surprisingly, your next enemies there will be synthets and aliens at the same time. Both can see through your camouflage. Synthets can be harpooned from a long distance but don't come too close. They won't spot you, but aliens will appear and outnumber you if you will be distracted by synthets ahead. The recommended tactic here is: kill the first synthet with a speargun, come closer and kill all aliens, then kill the second synthet who is standing with his back to you.

The tunnel turns right. Follow it and fight another pack of aliens on your way. You will see an open door to the right. Go in and follow a corridor until you come to a nondescript room. Fight a small group of aliens. Again.

Now traverse down by jumping from ledge to ledge until you come to another open doorway. You will hear sounds of skirmish. Pretty soon humans will be outnumbered by aliens and get killed and you will have to fight the rest of aliens. Hey, how did the humans get there, by making huge jumps just like you?

Never mind. Just follow the tunnel until you come to another skirmish. And again humans will be killed by aliens and you will have to deal with the rest. There are two pits in the hall ahead. Jump to a bigger one and follow the narrow tunnel until you drop down to a vent shaft. It's impossible to get lost. Just drop down until the level ends.
