Cheat Codes For Ghost Recon
Springfield Elementary
Hit & Run Meter
One of the most important aspects of the game, the Hit & Run meter, determines if the police will be chasing you or not. If you destroy a lot of things, and run over a lot of pedestrians, your Hit * Run meter will soon go into the red zone. This is to warn you that you are too far into destroying things. If you remain calm and do not hit anything or anyone, the rating drops significantly. You can also switch vehicles to cool the rating down some.
Levels
There are seven different levels in the game. In most every level, you will play as a different character; first being Homer, second being Bart, etc... You can revisit a level after you defeat it, as well, in case you missed something along the way.
Missions
These range from running errands to beating a certain character in a race. There are 49 missions that spread out over eight different levels in the game. If you fail a mission enough, you will have the option to skip it. My fellow IGN Guide writing buddy, Hil Goldstein, told me that in almost every mission that requires you to go from on point to the next, the timer doesn't start until you get into your car. Park close to your next goal, then when you get the mission, you can walk to your car, get in, and be done with just 5 or 10 seconds taken off the clock.
Street Races
There are three Street Races per Level in the game. You can find Nelson, Milhouse, and Ralph Wiggum all with flags throughout each Level, and it seems as if Marge's annoying sisters are behind it... Noteworthy tips include the fact that you do not have to run over the blue, circular checkpoints. There are also completely random challenges in Springfield from Louie and Legs that are not covered in this guide due to obvious reasons: They're random.
Bonus Missions
There are a few of these in the game, and they handle pretty much like the regular missions, except you likely earn a reward for completing them. They are also a little tougher than the casual mission, as well.
Gags
These bad babies are references to the Simpsons world of Springfield. If you spot a blue aura surrounding an item, press the button that you enter vehicles/buildings with to activate a gag from the show!
Collector Cards
The Collector Cards are also references to the Simpsons episodes, as they are a basic layout for what each described show was about, including quotes that scroll along the bottom of the menu. This is a game for the fans, that's for sure.
Wasp Cameras
These things have been spotted several times around town, and likely have a connection to those Black Vans that have been appearing throughout town. They can attack you with electricity, forcing you to lose money (ala, Sonic The Hedgehog). You can jump into the air and punch them to eliminate their threat.
Vehicles
There are plenty of vehicles that you can find, or purchase, in the levels of the game. Most of the purchases pop up throughout the game after certain missions are complete. To find out where to buy them, try reading the last paragraph or sentence of each mission to see if any have became available. You can also unlock vehicles through completing the Street Races.
Costumes
You can purchase different costumes (or 'skins') for your character to wear at different places where there tends to be a dollar sign. In the first level, it is in the Elementary School and Apu's Kwik-E Mart. Use this as a fast reference in where to look, although we will add the locations in the Missions walkthrough.
