X-COM: Add tons of money to your account: Use a sector editor (such as Norton DiskEdit) and edit LIGLOB.DAT in your saved game's directory. Overwrite the first 8 bytes with 64 64 64 64 00 00 00 00... You should get about 1.68 billion dollars. (In case you are wondering, 64646464h is a hexadecimal number. In decimal it is 1,684,300,900.) You can also use FF FF FF 7F 00 00 00 00... Which will give you about 2.1 billion dollars. (7FFFFFFFh = 2,147,484,647) I am unsure if I would call the following cheats, but the followingfeatures can certainly be unfairly exploited: 1. Psi-Amp auto armament bug/feature Your troops' psionic strength is discovered when they attend psionic training. However, if you carry Psi-Amps with you in your Skyranger, thePsi-Amps are automatically deployed to soldiers with the highest psionic strenth -- whether they've been to training or not. This allows you todiscover your best psi people without having them attend training. Keepthese people off the front lines; they'll make much better PsiCorps. 2. Scientist/Engineer salary bug/feature You only pay salary to scientists and engineers who are at your base onthe first of the month. To avoid paying them salaries, transfer them toanother base before the first of the month. You won't pay salary to personnel who are en-route to another base. 3. Partially-spent clip bug/feature At the end of an assault you'll have lots of partially used clips. Ever wonder why some clips are returned to inventory while others aren't? If a partially spent clip is loaded in a weapon, it is discarded at the end of the assault. If a partially spent clip is NOT in a weapon, that clip will be considered full and collected at the end of the assault. The moral of the story is to unload every weapon from fallen aliens and soldiers.
