Terrain Cheats
Six cheat codes alter the terrain and thus make getting around easier, or at least more interesting. "Graphics.toggleWater", for instance, will turn water on and off, which can make it substantially easier to move wherever you want. Meanwhile, four cheats, including "Map.generateGoodies", "Map.generateBonuses", "Map.generateFeatures" and "Map.generateRivers", will replot all goodies, bonuses, features and rivers, respectively, which you may want to do if you are playing this scenario for the second time and would like to add some variety. Finally, "Map.eraseGameElements" will remove all rivers, features, bonuses and goodies entirely, leaving nothing in the world but you and your foes.
Unit Attribute Cheats
While city-related cheats are irrelevant in the "Afterworld" scenario, all cheats related to individual units are especially relevant. These unit-related cheats can be invoked with simple keystrokes but must first be activated with the cheat code "Game.toggleDebugMode". Hold "Shift" and press the "]" key in order to increase the strength of a highlighted unit by 0.2 or "[" to decrease the strength of a highlighted unit. Either of these cheats can be used to increase or decrease the scenario's difficulty, depending on whether you use the cheats on yourself or your enemies. You may also hold "Ctrl" and press the "+" (plus) key to level up a highlighted unit. If you need money to purchase upgrades, holding "Ctrl" and pressing "4" will give you 1,000 gold.
World Editor Cheats
The preceding cheats give you a limited or imprecise means of changing the scenario. If you want more precise control over what you are altering and to what extent you are altering it, begin by entering the cheat "Game.toggleDebugMode". Now hold "Ctrl" and "Shift" and click the left mouse button; this brings up a prompt that will allow you to insert a unit of your choosing into the scenario. For an even greater degree of control, hold "Ctrl" and press "W" to gain access to the World Editor. Now you can alter the terrain and even change the number and types of enemy units you will encounter.
