X-Com: Terror from the Deep Cheats

More money:
Enter AEIOU as a base name. Quit your game and start again. You'll start with much more money.

Better soldiers:
Enter JUSTLIKEME as a base name. Quit your game and start again. You'll have better soldiers.

Free Manufacturing:
Go to the manufacturing screen in the game start to manufacture something but don't apply any technicians or place in amount of units to produce. Just select OK, and go straight back to the product selected. Apply as many technitions as you want but only produce one item. When the object you selected is finished, go have a look at your money it will still be the same as your materials used for making the product (zibrite and aqua plastics)...
This is very useful when manufacturing expensive units such as tanks.
