10. Resident Evil 4 (PS2/GC)
'Resident Evil 4' departed from previous incarnations that have turned gamers into zombie killers since the Clinton administration. While most gamers know Capcom doesn't prefer push-button codes, the developers manage to incorporate cool secrets hidden within the game.

9. Age Of Empires III
PC gamers must work harder than their console brethren to activate cheats, but it's a worthwhile tradeoff. 'Age of Empires III' rose high on the anticipation barometer, and strategy fans were not disappointed. For those who like to play games their own special way (i.e. by cheating), check this stellar code from one of the 2005's best games.

8. The Warriors (PS2, X)
'The Warriors' movie influenced a generation to rumble on the streets, and now, the fighting game's set to do the same for this current generation of lost souls. If you prefer to get your beat on video-game-style, Rockstar's console adaptation might do the trick. Plus, 'Warriors' comes with a parade of cool codes. Check this one for starters.

6. Need For Speed: Most Wanted (PS2, X, GC, X360)
The 'Need For Speed' series reinvents itself every couple of years and 2005 was an "on" year for EA's flagship racing title. Arcade racing fans lapped this one up, making it one of the hottest racing titles this year. Cool cheats also help, so here is one courtesy of AOL and CCC.

5. God Of War (PS2)
Loosely based on Greek mythology, this inventive action game was a runaway hit for the PlayStation2. Sony is pretty adamant about removing any push button codes from their games before they hit store shelves so often you'll just have to be happy with hidden in-game secrets. While we're sure Kratos would rip gamers in half for cheating, we won't snitch if you don't. Deal?

4. F.E.A.R. First Encounter Assault Recon (PC)
Funny that the First Encounter Assault Recon team happened to use the acronym F.E.A.R. since we were terrified for our lives when playing this action/horror shooter. Want even the odds against things that go bump in the night? Activate this invincibility code and send creepy-crawlies .

3. Peter Jackson's King Kong (PS2, X, X360, GC, PC, PSP)
The big ape's cleaning up at the box office and gamers have discovered there's more to this game than Kong's pretty face. This first-person shooter plays differently than usual shoot-everything-that-moves game, though technically, players have to, um … shoot everything that moves. Still, 'Kong' manages to be decidedly different and altogether awesome. To kick serious rump on Skull Island, this code will help.

2. Call Of Duty 2 (PC, X360)
No surprise -- 'Call Of Duty 2' is the best-selling game for the Xbox 360. This just proves that as we move towards World War III, World War II is still pretty darn popular. In fact, this World War II redux sports some cool exploits and codes.

1. Grand Theft Auto: Liberty City Stories (PSP)
Rockstar's GTA series has been a haven for cheaters since its inception and the franchise's latest installment for PSP doesn't veer from the course. 'Liberty City Stories' sports loads of codes, but be warned -- using them could affect your saved games.
