Equipment

The philosophy of Equipment is simple: to add variety to the combat during gameplay without unbalancing the game. Plus, the variety of equipment can benefit a player in different ways.

Halo: Combat Evolved
In Halo: Combat Evolved, the only Equipment available on demand was the Flashlight. You could pick up two types of bonus Equipment, the Active Camouflage and the Overshield, both types of Equipment would only last a limited time before wearing off, as in Halo 3.

Halo 2
In Halo 2, the only available equipment was Master Chief's flashlight and The Arbiter's active camouflage (Though with a certain skull, Master Chief would gain camouflage as well). Although such equipment could not be collected or spent, they were always available for use (based on charge) being integrated into their respective armor. Much like the previous game, Halo: Combat Evolved, there were two types of equipment exclusive to the multiplayer modes, Active Camouflage and Overshield. After a while, the effect of the power ups would wear off, though this was quickened when fired on by enemies.

Halo 3
In Halo 3, equipment items can be used by Human players and AI units in both Multiplayer and Campaign, though the flashlight remains campaign exclusive. They are placed throughout Campaign levels and Multiplayer maps to add a new strategic (and sometimes humorous) option to the Halo gameplay mix. While most of the epuipment is Covenant manufactured, some is Human made, such as the Lotus Anti-Tank Mine (Trip Mine) and possibly the Flare. Others, such as the Auto Turret, are made by the Forerunners. While only one piece of Equipment can be carried at a time, they are usually worth their weight.

Trivia

 * In the January 2008 issue of EGM, in an interview with Brian Jarrard and Tyson Green, it was revealed 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 a 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.


 * The Radar Jammer, Flare, and Deployable Cover are no longer usable in Matchmaking, as all three could be used to reach unfairly high places; the former two using the Equipment Jumping glitch, and the latter by simply jumping on it after deployment.
 * In the new 2009 Halo 3 Action Figures wave, there are equipments included, and it should be noted that they all can be moved in some way as if they were activated; for example, the Radar Jammer included with the Olive Security-permutation Spartan has two handles on it that the Spartan can hold as if to be able to deploy the equipment, and these are connected to disk-like parts of the Radar Jammer that extend during use and, when deployed, jams everyone's (including your) radar showing the are multiple enemies nearby even though there might be none.
 * the radar jammer is everyones favorite stealth weapon
 * the bubble shield has only one weak spot

Glitches

 * The Radar Jammer, Flare, and Power Drain can all be used to "double jump".
 * In Forge, players often set equipment items to Instant Respawn, resulting in various interesting effects. Among other things, Instant Respawn Trip Mines can be used to overload a map.
