Tips: read before you start.
-The ammo and rations are not always in the same place for every game. Make sure you keep an eye out for them.
-Try not to waste your ammo.
-The tunnels with multiple corridor options are not always the same tunnel. Just pick a corridor and stick with it.
-Your flashlight/torch will turn on automatically for all tunnels and spider encounters.

1. Outside/Main hangar:
-Move ahead. Notice something crawling up the right side of the building.
-Enter the building. You’ll head up an elevator.
-In this next room, notice something crawling across a pipe. Grab ammo and rations and check out the door.
-Click the switch on the right to open the door.

2. Drill room:
-Check out the right room first (ugh, more blood; a familiar sight if you played the first game). Grab ammo/rations and click the black box/panel.
-Point all the knobs (including the 2 small ones) along the green line from the words “OPEN DOOR” to the red LED. Click the button and the LED should turn green.
-Head back to the drill room and check the left room. Grab ammo/rations and head through the open door (that’s the door you opened with the panel). Climb the ladder. Here’s how:
-Click where your hand needs to go next. So you click the left side of the first rung, the right side of the next, and so on, so forth until the arrow appears.

3. Maintenance shaft:
-Click the keypad next to the door. Call the intercom and click through the conversation with the pilot. Now you know:
-What you’re up against. (More alien creatures.)
-How to escape. (Get to the chopper on the roof.)
-The first number to the code panel. (0)
-Turn until you see some barrels. Move the single one on the left and note number 2=8. (Don’t forget to grab ammo/rations in this room.)
-Turn to the cutoff wheels. Click the wheels until you find the one that turns. Turn it all the way and the steam will stop, revealing another note: 3=2.
-Turn to the boxes. The clock above the boxes gives the final number. The circled sum is 8-4, which equals 4. So the code is 0824.
-Input the code into the keypad and head into…

4. Tunnel 1:
-Click through the tunnels, but make sure you grab all ammo/rations along the way. At the end of the tunnel is…

5. SPIDERS 1:
-Right now, all you have is the pistol. Aim carefully (point and click to fire), check the sides of the screen, and try to be as accurate as you can on this one, as you get a bonus for best accuracy over 90%.
-Ammo will drop, but your first focus should be on the spiders. Only grab ammo if there are no spiders around or if you absolutely need it.
-Good luck and try not to get hit. (You get a bonus for not getting hit as well.)

6. Ammunition room:
-In this room, there are four locked ammo cases (and extra ammo/rations around; don’t forget those). Fortunately, the combination for each ammo case in turn is scratched on the wall above it. Turn the pointers on the cases so they point the same way as the arrows.
-One ammo case has the KEY, another has the SHOTGUN. (These cases also have ammo; make sure you grab the ammo first.)
-Once you’ve opened all the cases, open the locked door with the KEY.

7. Tunnel 2:
-This is the same as all the tunnels. Don’t forget the ammo/rations. Waiting for you at the end is…

8. SPIDERS 2:
-These spiders shouldn’t be very difficult, but they will be getting harder. Try to save shotgun ammo (spacebar changes guns) and just use the pistol.

9. Kitchen:
-First, grab ammo/rations. Now check the kettle on the left.
-Click the plug to plug in the kettle.
-Click the red switch on the kettle to boil it. Click the kettle and you will control it.
-Head back to the big view of the room and use the kettle on the door to melt the locking mechanism.

10. Walkways:
-Ah, beautiful snow. Grab ammo/rations, then head forward and you will go up an elevator.
-This walkway is suspended. Grab ammo/rations (as usual). The arrows control the two walkways.
-Arrows on the left control near walkway.
-Arrows on the right control far walkway.
-Once you’ve made a complete walkway, an arrow will appear at the end of the walkway.

11. Tunnel 3:
-Hopefully you know the tunnels by now, hopefully you remember to grab the ammo/rations, and hopefully you know what comes with the territory…

12. SPIDERS 3:
-Now the spiders will start getting harder. You may want to switch to a shotgun on this one, and remember to watch the sides of the screen. (You may want to keep the pistol, however.)

13. Alcoves:
-Grab ammo/rations (do I even need to say it by now?), then check the left alcove. There are two more ammo cases.
-The combination (scratched on the wall) consists of one arrow; point all the pointers in that direction. One ammo case contains the MACHINE GUN (grab the ammo first); the other has ammo.
-Now check the right alcove and prepare to go EWWWWWWWWW. Notice the HAND among the remains, and use the KNIFE (you start the game with it) to cut off the HAND.
-Head back to the view of the door. Click the scanner by the door and use the HAND on the handprint scanner to unlock the door.

14. Tunnel 4:
-I really don’t need to say anything, do I? Just prepare for…

15. SPIDERS 4:
-On this one, it would be advisable to use your shotgun or machine gun, although I was able to defeat this level with the pistol without getting hit. Don’t worry, this isn’t the hardest one (okay, maybe you do want to worry :-o).

16. Pumps room:
-Here, you need to activate the pumps in order to refuel the chopper. Grab ammo/rations (again), then check the two pumps, one at a time.
-What you have to do is watch the dials for the steaming one, then click the wheel that corresponds to that dial.
-The 1st wheel corresponds to the 3rd dial.
-2nd wheel, 2nd dial.
-3rd wheel, 5th dial.
-4th wheel, 4th dial.
-5th wheel, 1st dial.
-Once both pumps are working, climb the ladder (same method as before). Now take a deep breath; it’s time for the big one…

17. SPIDERS 5:
-This is the hardest of all the spider levels. Use your machine gun and don’t forget the sides of the screen. Good luck; you’ll need it.

18. Roof:
-You made it to the helipad! Now all you have to do is click the arrow to get in the chopper and you’re free!!!!!

Congratulations!
