Perfect Dark

These will change the ally (and its weapon) on Co-Op IF it is a simulant.

Simply set up a multiplayer game against all Dark Sims with nothing but Remote Mines for weapons. It will only take a few seconds for the melee to begin, and you'll soon notice that Sims in Perfect Dark cannot detonate their own Remote Mines after they plant them!

Have a, um, er... blast. The only way you can possibly lose is if you blow yourself up on purpose, and this works wonders in inflating the stats on your bio.

I figured out a cheap (but VERY effective) way to beat every single combat challenge in Perfect Dark, each in as low as 1 second! No you don't have to have a GameShark or DexDrive, but you gotta have at least 2 controllers to make this one work. Read these directions carefully!

1.) Have player 1 select Combat Simulator and select Advanced Setup.

2.) Player 2 Presses Start

3.) Player 1 Selects "Load Settings" on the Advanced Setup menu, but does not select any setup yet, just stays at the "Load Game Settings" menu.

4.) Player 2 selects the challenge they want to beat in the Advanced Setup menu. Player 2 presses start until the green "...and waiting" screen appears.

5.) Player 1 Selects the Game Settings They want in the Load Game Settings Menu (NOTE: You must have a custom or already made setup, you cannot alter it after you load it.)

6.) Now player 1 can drop out or join the game it doesn't matter, of course staying in will give you 2 stars instead of just one.

If you want to save some time, make a custom setup beforehand. Choose a level, some sims and a limit. As long as any person can reach the limit or have the highest score you'll win the challenge.

On Area 51: Escape, at the very end, instead of finding a way out, you can go with Elvis. Once Elvis says, "Oh, no! We have a problem! It's a single seater!", run up to the consoles. Stand next to the console farthest away from the hangar doors. From that spot, stand as close to Jonathan and Elvis as you can. You should be able to hear them talking. After they're done, wait until the music changes. Once this happens, press the B Button on both of the consoles. The level should end. (Good way to get Invincibility, [Agent, 3:50 or less]).

Before completing the Crash Site mission, have the President die just before you reach Elvis' crashed saucer. The objective to rescue the President will register as complete, but during the cinematic, Jo will be talking to herself with no responses.

Use the following trick to hide your screen to prevent ambushes in multi-player mode. Hold R and press C-Down(2) to duck all the way down. When you are low to the ground, hold R + C-Down to hide your screen. Try to duck even lower when you are as low as you can get. Turn off radar to add to the fun.

In advanced setup, set the handicap up to 1000%. You will not die as much, and can get better medals.

Go to the security terminal with your phoenix set on explosive shells. Get in a position so that you can turn off the security console, but do not turn it off. Take out your phoenix, shut down the security, and kill the black guard before he kills the Falcon 2 guard. Note: The guard has an aggressive personality and will run after guards from far away.

Take care of both NSA lackeys (one at the escalator and the other at the freight elevator) and the last one at the station before subverting security, you will get two magnums.
