Hints
Safe areas in facility
If you are being chased by aliens, just enter a vent
shaft or run into the infirmary (the starting room of the game).
The infirmary is a good choice to use as a "base" because
it is in the center of the facility (and aliens will not enter
it). Please note that an alien can not open the door, but an alien
will enter the infirmary if you move near the door to open it.
Make sure that you look carefully at the screen before you open
a door.
When you open the door with the blowtorch, you will notice that
there is another door in front of you. As long as you do not open
this door, you will be safe. However, there will sometimes be
an alien in this area.
Using the flamethrower
The flamethrower can only destroy alien eggs.
