Gravity rifle

The Gravity Rifle is a deleted weapon in Halo: Combat Evolved.

Summary
The gravity Rifle was going to be a Covenant Sniper Rifle, but Bungie decided to delete it, like they did with the Engineer. However, the model in still within the game's code, but was never made a proper texture, first person mode and projectile.

Halo: Custom Edition
Though the weapon was deleted from the game, the code still exists within the game's code, and is possible to use in Halo: Custom Edition in certain maps using the devmode command cheat_all_weapons.

There is no animation for it being fired, but it will create a bright flash when shot. It's similar to the flamethrower, except it only starts a fire when you point it at a solid object.

Despite having no reticule or scope, the weapon is extremely accurate. Also, it has unlimited ammunition, due to it not having a set clip or magazine.

Trivia

 * If you go to pick it up, the screen will say "Press E To pick up need string entry here". This is due to it not having a string entry.
