Cheats in GTA IV

Be warned that entering some of these cheats in the game will disable certain achievements in the 360 version, so do so at your own risk. Accessing Secrets is different than cheats, and will not affect the status of your gameplay. There is no way to unblock the achievments unless you re-load your game and haven't saved after the cheat has been activated. --MalavikFurther warning is needed, after talking to rockstar games live certain cheats will affect the game drastically. Say the armor, health and ammo cheat could possible glitch the game and make things changes (in my case all the cars at the safe houses disappeared. Not to say that specific cheat will do that, but i have used unnumerable cheats hundreds of times without thougha and just recently i noticed my cars are gone. However if you use any of these cheats but still desire all the achievements, you can simply start a new game file and complete the first mission. Then there are no blocks on the achievments.


 * Calling any other random number you find in the game from stores, posters, ect. will allow you to prank call that number.
 * Note that out-running cops who try to stop you skipping islands when you are in a spawned Jetmax will NOT give you the Walk Free achievment, but you can get it later on in the same save file after you are killed.
 * If you have completed all 30 of Stevie's Car theft missions, you can pawn any car you want for money like you did in his missions. If you pawn cars, you can make as much money as you want. The cars are worth about 1/3rd of what they were in his missions but you can do it over and over and over again.

Keep in mind that this table is presuming that the car is just spawned and has not taken any damage.

The FIB Buffalo is the only unsellable spawn car. The Annihilator cannot fit in Stevie's garage and it is unlikely the Jetmax will either but it has not been proven.

Most cars have a low sell value, driving gently into a wall enough to scrape the pain will dramatically improve the value of certain cars, the SuperGT spawn and sold will get you $8,000, driving it slightly into the corner of the garage enough to ding it and then selling it will sell for the full retail value the $10,500 (i have had experiances where i have gotten 10,800.
