10 Classic Video Game Glitches That Allowed Us All To Cheat
8. Halo: Combat Evolved - Infinite Ammo
Even this immensely successful series had game breaking glitches such as frozen elites, bypassing walls, fall damage reduction, and unlimited enemies. However the most notable of these glitches was the infinite ammo glitch, which could essentially be used with any weapon of choice throughout the game.
The glitch was done by taking any weapon (except for the Plasma Rifle and Plasma Pistol) and emptying the magazine. When the magazine is empty, before the reload animation begins, switch the weapon with any other weapon on the ground. The game will think that the weapon is still being held and that it's being reloaded but when the weapon is picked up again it will have the same amount of remaining ammo as when it was dropped.
Abusing this glitch on all levels with any weapon with the exception of the rifle and pistol would make the game easy even on the hardest of levels, of course there were a few limitations such re-doing the glitch every time a reload is required. Some weapons were slightly trickier as the reload animation wouldnt appear, making you re-do the glitch again.
Ultimately the small limitations were outweighed by the advantages. Here is a demo of a player abusing the glitch for infinite sniper and launcher ammo:
