TR/9 trip mine

The Trip Mine is an equipment item that has been seen in the alpha build of Halo 3 and is usable in the Halo 3 Multiplayer beta. It has also been seen in the Halo 3 ViDoc "Is Quisnam Protero Damno."

Background
The Trip Mine, like the Bubble Shield, Power Drainer, and Portable Grav Lift, are all in the category of equipment. It can be deployed using the "X" Button. It may be the same thing as a Lotus Antitank Mine, as both are activated by nearby motion and inflicts lethal damage to vehicles.

The trip mine can be activated by proximity or touch, but will not be activated by a crouched player. Once deployed, it can be identified by a high pitched beeping noise or by a distinctive flashing red light on its top. It's blast radius is considerably larger than a grenade explosion or rocket explosion. The activation radius is smaller than the kill radius. The trip mine can not be deactivated once deployed. However, it can be remotely activated by projectile weapons or grenade explosions.

The trip mine has the ability to attach itself to vehicles if it is deployed nearby. There is a several second delay between deployment and detonation, but it will stick to vehicles immediately. It will detonate by itself after a period of time.



Tactics

 * When running away from a moving vehicle, a mine can be deployed in front of a moving enemy vehicle. Be careful though, it may kill not only the driver and passengers but you as well.
 * If you deploy a trip mine on top of a Man Cannon, the mine will go flying out into the battle field.
 * Also deploying the mine in the general area where the Man Cannon deposits players will kill the next person to man cannon from the base. Don't do it to your own base if your intentions aren't being a team killer.
 * Putting a trip mine in front of an unmanned vehicle will result in a nasty surprise to the next one entering it.
 * Place them in areas that are hard to see and that players need to go. A perfect example is in front of the mancannon. There is a downward incline before the mancannon. Placing one here makes it unnoticable to the player entering the mancannon. Be careful or the trip mine may be launched by accident.
 * Be sure to inform your teamates of the locations of trip mines. Otherwise, you may get a betrayal if a teamate steps on it.
 * Also when near the enemy's warthog spawn see if you can place on the underside of the vehicle by deploying while next to the side of the warthog.
 * In Forge trip mines can be deployed as a defensive "wall" for tight choke points.

Spawns
Valhalla is the only map that the trip mine spawns on in the Halo 3 Multi-player Beta. It spawns next to a pair of spikers on top of each base. Another copy will spawn if the original has been taken.

It is now confirmed to be in the final game according to the online halo 3 manual posted by microsoft.
