I was playing a co-op game (local xbox) on the level Gravemind. At the first Grav Road we killed all the guys accept the Grunts. Then we killed the Grunts and they had Purple Armor. Anybody know what this is.
If it's a dark purple, it's probably just spec-ops colouration under the right lighting.
Halo 1 has a similar thing happen occasionally on the level Keyes; some areas give the spec-ops an almost bluish-greenish look.
