Click on "Options" after a game is started. Click "Edit Units" to adjust prices, defense score, offense score, locations, movement, etc.
CPU cheating
When the CPU senses an overkill to a certain level, the message "Max History Log Full!" will appear. You have to reboot the CPU to continue.
Extra IPCs
Save the game during the "Collect Income" phase. Exit the game and reload, and you will gain the income again. Repeat often to accumulate a large amount of money.
Free items and strong men
When you begin a new game, go to the options screen and select "Unit Edit". Make anyone for any country as strong or as cheap as you want. The cost will never go down lower than one. When you start the game, go for weapon upgrades and hope for industrial technology. This will make everything one IPC fewer, making everything free.
Free units
Allow your IPC (Industrial Production Certificate) supply to get over 250. The game will sometimes give you free units. It will most commonly happen when over 450, but still may happen at times if the total is between 251 and 449. Build so many units in the game until the IPC window freezes. The game will give you free units the rest of the game.
Unlimited lives
