1. On each level of a station, look for a code symbol. (Station 1 has only 1 level; all others have
multiple levels.) To move to different levels within a station, use the stairs and sonic doors. You might
want to write down the code(s).
2. When you have found the codes on all levels of a station, search for a room with a flashing
horizontal bar. This room contains the self-destruction mechanism. When you arrive at this room, move the
directional control forward to display codes and left or right to move between the entry positions. Be sure
to enter the codes in the correct sequence.
3. When you have entered all codes, press the fire button, and race to the teleporter room. A number
countdown appears to show you how many seconds you have to make it.
4. When you arrive at the teleporter room, touch the teleporter to escape the station before it explodes
into smithereens. Once you touch the teleporter you are transported to the next station.
Strategy
Learn your way around the stations by drawing a map as you go.
If you are in a multi-level station, write down the code you find on each level so you will be able to
remember the entire code when you enter the room containing the self-destruction mechanism.
Avoid losing all of your energy. If you lose all of your energy, you can't use a weapon. If you can't use
a weapon to destroy aliens, you will not be able to get oxygen. If you can't get oxygen, you will not live
long. Neither will the human race.
