Perfect Dark/Walkthrough

Because the gameplay of each level is very much different depending on difficulty mode, this walkthrough will cover each difficulty mode separately, in the order Agent, Special Agent, Perfect Agent. The walkthrough given for a particular difficulty mode will not contain gameplay spoilers for a more difficult mode, and will assume that you have already played all easier modes.

Each mission, other than bonus missions, has a difficulty where a target time is given. If the level is cleared in the target time, a cheat is unlocked. This walkthrough will give a strategy to achieve the target time, and will assume that you have already played the corresponding difficulty mode for that level.

Be aware of the settings. It is highly recommended to have the brightness (gamma) turned up in Options. Although the auto-aim option is useful, there are times where it is better to have it turned off.
