Mark 3 Fusion Grenade

The Mark 3 Fusion Grenade is a special grenade manufactured by Infinity Armories. It is the UNSC equivalent of the Plasma Grenade, and to the traditional Frag grenade.

Function
To arm it, press the button on the top to arm it, turning the energy color red. Upon detonation, it fuses nearly anything it comes in contact with in a diameter of 2 meters(6ft). It also doubles as a time bomb.

Coloration
The Fusion Grenade has different stages, instead of a fuse. When idle, its core is green. When the timebombs timer is set, it turns from green to blue, to yellow, to red, then detonates. It can be mounted to a wall, doubling as a trap grenade. Once armed, it uses an radar to identify targets. Its color changes as an enemy comes closer. Come closer and it changes colors as it does when it is a timebomb. Once an enemy distances from it, the stages revert and eventualy turns back to green.

Appearance
It is very similar to the Halo Reach Fusion Core, although much smaller in size.
