X-COM: UFO Defense Codes -

Hint: Lower payroll:
Transfer all scientists and engineers to another base just before the end of the month. If they are in transit at the end of the month, they will not be paid.

Hint: Quick money:
Investigate a crash site, then research "Alien Alloys". Manufacture a large amount at $3,000, and sell it for $6,400. Sell all alien bodies except for one. Research the body, then sell it to receive $20,000.

Hint: Save men:
Note: This trick requires a memory card. Save the game after starting a mission. Play through your turn without losing any men, then save the game after the alien's turn. Continue game play until one of your men dies. At that point, abort the mission and load the saved game. Use a different strategy from your last attempt to complete the mission.
