9. Health & Armour
Another cheat code that has become virtually synonymous with the GTA series is health and ammo. As well as being able to shoot people in Grand Theft Auto, you can also BE shot, which is why it sometimes pays off to have a health code handy if you're tackling a particularly challenging mission and find yourself surrounded by heavily-armed goons. This code is again missing from the early list of discovered cheats but much like ammo, we expect it to be discovered and shared later on this week, when everyone's had a hands-on experience with the game and a chance to poke around. The health and armour cheat pretty much does what it says on the tin, really, and has saved our bacon on more than a few occasions during a hairy moment or two.
