Gruntpocalypse

Gruntpocalypse is a Firefight gametype in Halo: Reach Firefight.

Overview
Gruntpocalypse is similar to the Bonus Round featured in Halo 3: ODST Firefight. Likewise, it involves a massive army of Unggoy of various ranks that will spawn continuously. All skulls will be activated during the match.

Trivia

 * In Halo: Reach, Gruntpocalypse is widely regarded as the best way to earn good amounts of cR over a relatively short period of time.
 * These grunts are much less likely to run away when injured. However, they will still run if their leaders and allies fall beside them.
 * This game type might seem easy, but it's not, at least not on higher difficulty such as heroic.
 * Every grunt squad (4 in a squad usually) that is 'spawned' usually has one grunt with a fuel rod or plasma launcher.
 * The priorities of what to kill first for each squads is as it follows, Heavy grunts(the ones with fuel rods or plasma launchers)>Spec ops grunts(the one with the silver Armour and helmet, usually the leaders)>the rest(which is the remaining ones with plasma pistols or needlers).
 * Grenades in a small area/ room is very effective. Like the staircase to the rooftop on Beachhead.
