Equipment

In Halo 3, Spartans, Brutes and Elites, can carry one extra item of equipment – deployed using the “X” button on the controller. Equipment types vary dramatically in purpose, functionality and appearance, but all can be used with deadly or strategic force. To follow is a simple explanation of what each does, and where you can find at least one of them. There may be more to find and their availability is subject to matchmaking rules.

The philosophy of equipment is simple – add variety to the combat in Halo 3 without displacing balance. The simple fact is that Equipment items, once deployed can be used by both attackers and defenders. Someone on your team might accidentally activate your Trip Mine, and a Bubble Shield is a geometric spherical shield – sure they can’t shoot in, but you can’t shoot out either. Suffice to say that equipment can turn the tide of battle if used correctly. To make it more balanced, it takes longer to deploy equipment than in the Halo 3 Beta, but you can launch it farther. It is not entirely clear which faction - Human or Covenant - manufactures each piece of equipment in the first place without doing research on the specific equipment, as both are seen utilizing it in the single player campaign.

Trivia

 * In the January 2008 issue of EGM, in an interview with Brian Jarrard and Tyson Green, it was reveiled that there was a piece of equipment cut from the final game known as "The Vortex". It was said to be deployed the same as an Power Drain, but would instead create a mini black hole that would "suck in any object within range, and diverting its course into the black hole, and away from your face." It was even able to affect nearby objects such as the Fusion Coil and even other players. The design was cut due to the fact that it was too "expensive" from a networking and performance standpoint.
 * There is some speculation that the Trip Mine may be the famed Lotus Anti Tank Mine from the Halo novels, although it has 2 spokes less than what is mentioned.
 * When you try to drop a piece of equipment on a vehicle or object (like a crate), the equipment will go through the object and end up under it. This happens to prevent players from driving around in vehicles with bubble shields or other equipment around them.
