To summon a cheat code, press Enter during the game and enter one of the following codes below. After that, press Enter again to initiate the cheat. The codes are not case sensitive. Cheats that summon units and provide free resources are repeatable but those that affect certain units only require a single input. Cheats can be repeated continuously through copy and pasting which allows the player to initiate the same effect with minimal effort. This can be done by pressing Ctrl C after typing it out then repeating the action of Ctrl V after pressing Enter. On older computers, players may need to right click and perform the task manually instead of using this shortcut method.
Cheat codes that summon new units will always spawn at the Town Center and likewise will not be applicable to players without one. If a player has more than one Town Center, the unit will spawn near the one that was most recently built, and will continue to spawn there unless a new one is built or the current one is destroyed. The act of summoning cheat units is similar to the act of training new units from the Town Center. Consequently, if the Town Center is researching a new Age, the cheat unit cannot be spawned.
Cheats that affect certain units does not apply to enemy units converted by the player. To maximize combat potential, players should type the code before researching specific technologies that benefit that unit.
- BIG BERTHA - Transforms Stone Throwers, Catapults and Heavy Catapults into Big Berthas, which have more hit points and most importantly, greater range and much larger area of effect.

- DARK RAIN - Transforms bowmen and all foot archers into Stealth Archers. They turn into trees when standing still and can walk on water. Previously researched technologies that benefit archers would no longer apply once this cheat is summoned.
- ICBM - Ballistas and helepolises gets 100 range. However, this does not affect line of sight. As a result, any moving target that is beyond the original range cannot be attacked. Fortunately, it can attack any building discovered through the fog of war. This makes it useful to attack Wonders as a last resort.
