Oblivion Console

The console is a powerful in-game tool available to PC players. From the console it is possible, while playing the game, to enter commands that will alter most aspects of gameplay, and it is also possible to obtain detailed information about NPCs, creatures, and other items in the game. The console is only available on the PC; there is no way to use the console on the Xbox 360 or PS3 platforms.
