In a mix of alchemy and computer code, these procedurally generated landscapes will, it's promised, be the same on everyone's computer. Which means that you could, if you were so inclined, create a mission that takes place 100km away from the main areas included in the game, and the randomly-generated terrain to reach it as well as the area itself will be exactly the same for everyone who plays it. The AI will also be able to find itself around this terrain as well. It's a stunning display of computer wizardry, and has unlimited potential for mod teams to play with.
