Enemy Infestation [cheats]
To enter the in-game cheat mode at any time, type any code as you play
(it won't work if the game is paused). Then hit Enter. If it doesn't
seem to work, try them again. Type them carefully when you have colonists selected:
Pressing certain letters can cause a selected colonist to initiate a
behavior trait (for example, pressing F gives the Flee command).
gsaheal - Heals all colonists (not terminated) back to full health.
gsaroof - Removes all roofs (takes awhile) so you can see into rooms.
gsaswap - Swaps sides (allows you to control aliens);
use following the kill cheat to eliminate selected aliens.
gsakill - Kills selected characters.
(your own, or swaps, selects, and kills aliens).
gsastop - Stops both aliens and colonists from acting, causing them
to just stand around; type it again to toggle it off.
gsabog - Creates a BOG weapon at the cursor that when you pick it
up gives you extra defense and lets you lock doors.
gsaknife - Creates a KNIFE weapon at the cursor that when you pick
it up makes you invisible to aliens (they won't go for
you when they would normally see you).
gsacmdr - Creates a commander at the cursor.
gsamedi - Creates a medical officer at the cursor.
gsaboff - Creates a technician (boffin) at the cursor.
gsawin - Wins the level no matter what.
(so you can continue to the next).
One of the most difficult missions is The Swarm. Here's the key to
solving it: rescue Bonnie (the electronics expert), get her healed,
and lock the airlock door.
Keep an eye on your colonists' reactions, especially if you change
them. Having a scientist set to "fight" instead of "hide" is a quick
way to lose a mission.
Tip 3 Easy wins:
Save the level as soon as you begin; and if the Big Orange Gun or the Ray
Gun have been given an unfavorable effect--either "grow" or "multiply"--
restart the level from the main menu.
