Perfect Dark

Find all weapons in the solo missions and get at least Bronze Rating for each weapon on the Carrington Institute Firing Range.

Complete all solo missions in Special Agent Difficulty or better.

To get this cheat you have to beat the level in under the time limit. Also on the difficulty setting listed.

Beat Skedar Ruins:Battle Shrine in under 5:31 on Perfect Agent difficulty.

At the "Perfect" menu where you can select the solo missions, Carrington Institute, etc., select the "Combat Simulator" then immediately press B. You will have the same background as the Combat Simulator in the Carrington Institute "Perfect" menu. When you exit the menu it returns to normal.

As everyone who has ever failed in this level knows, if the crate you're lugging around gets blown up by stray gunfire, you fail the level due to not being able to access the research section.

Thankfully there's a nice glitch that allows you to bypass having to lug around that annoying crate altogether. The enemies in this area wield Dragons as their weapons, which is the key to the entire thing. Blast your way through the level until you're at the section of the wall that you need to blow up, then access the secondary function of the Dragon -- Proximity Mine -- and place it at the base of the wall. All you need to do from there is stand back and shoot the Dragon so blow both it and the wall up.

You've just accessed the research section without using the crate of explosives, and this glitch works even if you blow the crate up first despite the game telling you that it's a mission failure.

All that is needed are 2 controllers, (3 or 4 if you want the remaining stars), and a simple scenario.

First, plug the 2 controllers in and head to Combat Simulator with a simple scenario saved (such as 1 MeatSim, Kill Limit 1). Take the 2nd controller, head down to ''load game'' and highlight what you will (in the future) use for your Challenge. Take your 1st Controller, and pick a difficult Challenge, such as Challenge 30, and select it until it says ''START CHALLENGE'' (the background will be red at this time). Pick up your 2nd controller, load your simple game, and start your Challenge.

What you just did was fool the game into thinking you're playing the Challenge, but you're actually playing a homemade scenario! Kill the MeatSim, and it's a game won. You will gain the star for the Challenge, and it's rewards gained from beating it.

Go to Carrington village:Hostage one and make your way down to the wine cellar. Shoot every single bottle and Carrington will say "Act your age, Joanna."
