Halo has skulls. Gears has cogs. Grand Theft Auto has packages. But this year's most rewarding collectible hunt isn't in any of those games... it's in Call of Duty 4.
Scattered throughout the shooter are 30 hidden laptops, capable of unlocking some of the most useful - and bizarre - cheats we've ever encountered. Ranging from infinite ammo to super powered grenades to a "silent 1920s movie" filter (seriously!) these things can transform the game until it's nearly unrecognizable.
Want to see what we're talking about? The video below demonstrates all of Call of Duty 4's cheats in action. When you're done, and dying to try the special modes out for yourself, click through the page tabs on the left. Our mission-by-mission walkthrough will guide you to each and every laptop with text, screens AND video. Happy hunting.
