Support weapon

Halo 3 introduces a new class of weapons called support weapons. While carrying there, your view switches to third person and you walk slower. You are generally more powerful, but also more vulnerable and much less versatile.

 * Gravity Hammer Seen in Et Tu Brute? ViDoc (possibly just a normal weapon as seen in leaked shots)
