Dylan Burke is finishing the job his father failed to complete on LV-426. He must be stopped.

Playing the game
The play screen consists of the primary game view, scrolling message display, scanner battery indicator and egg counter icon.
- The scrolling message display gives critical information during game play. It will show next steps, alerts and status updates.
- The scanner battery indicator will be green when the map scanner is available. A red indicator means the battery is charging.
- The egg counter icon shows how many eggs remain on the current level. Return to the transport beacon when it reaches zero.
Search planets for alien eggs. Move over it to add the egg to the cargo bay. You must collect a total of 12 eggs before you can go to the last level.
All eggs will hatch if given enough time, so try to find them as quickly as possible. Eggs will hatch facehuggers which will evolve into large aliens.
When the egg counter shows there are no more eggs in the level, return to the transport beacon to go to the next planet.
The transport beacon is where you start every level. When your egg counter shows zero, return to the beacon to leave the planet and start the next level.
Move on top of the beacon and wait for the dropship to land. Then travel to the next planet to search for more eggs. Watch the message display for updates.
The dropship is available only when there are no more eggs on the planet.
Toggle the map scanner using the Z key. Use arrow keys to pan large maps.
The map scanner shows the location of your character (red) and the transport beacon (blue). The green dots show the location of eggs, aliens and dead bodies.
Turning on the map scanner uses battery power. The battery must recharge before you can use the map again. The battery icon will turn green the scanner is available.
Beware! Aliens don't stop while you're using the map, so don't hesitate for long.
The motion tracker detects when aliens are nearby.
Sound required for motion tracker. Headphones recommended.
During play you'll hear a frequent "blip" sound. These blips will increase speed when aliens are nearby.
The motion tracker only detects moving aliens. It will not detect eggs, dead bodies or jungle aliens.
Weapons and equipment
There are 2 primary items to help survive. Scattered around every level are dead bodies. Search a dead body and you'll equip either a pulse rifle or bait stick.
Use the equipped item by pressing the X key.
Tip: Don't search every body you find. Leave some for when you need to escape and are being chased.
The pulse rifle only has one shot and will automatically target the nearest facehugger or alien. Both are killed with one shot.
Searching a body while having the pulse rifle equipped does not increase the ammo count. The pulse rifle only ever has one shot.
Beware! The pulse rifle will not target or shoot jungle aliens.
The bait stick can be used to lure and distract aliens.
Place the bait stick and any nearby aliens will be attracted to it and will not chase you. The bait only lasts a few moments, so use that time wisely.
Warning! Facehuggers are not attracted to bait sticks.
Pre-mission scans will show how many eggs are on a planet but the report does not indicate how many aliens might be lurking on the surface.
There are 3 types of aliens to watch out for:
- Large aliens
- Jungle aliens
Being caught by an alien is instant death. Game over, man, game over!
Facehuggers are small aliens that only emerge from hatched eggs. Facehuggers seek out dead bodies which they then use to evolve into large aliens.
Facehuggers will chase when close but they are slower and less aggressive than large aliens.
Facehuggers can be killed with the pulse rifle but are not attracted to bait.
Large aliens may already populate planets before arrival, but they are also created when facehuggers find a dead body.
Aliens will chase when nearby and are faster than facehuggers. Thankfully, the landscape often provides plenty of twists and turns which you can use to confuse them and escape.
Large aliens can be killed using the pulse rifle and are distracted by bait sticks.
Jungle aliens are camouflage and hide in bushes. If within range they will attack with paralyzing acid, stopping your movement momentarily. Their attack will not kill you. After attacking, they retreat and go back into hiding.
Jungle aliens cannot be killed. You cannot shoot them with your pulse rifle and the bait stick has no affect. It's best to avoid them when possible.
Beware! Jungle aliens do not appear on map scans
The final mission
After you fill the cargo bay with alien eggs, you'll go to the last planet, PCO-8. You must blow up the planet and with it the Queen alien.
Eggs are not collected on this level.
First, find and arm 3 remote bombs by moving on top on them. Then find the detonator to start a countdown. You'll have 40 seconds to get back to the transport beacon and escape. Good luck!
Warning! Neither the bombs nor the detonator appear on map scans.
