Guerilla

Guerilla is a Halo 3 Meta-Game Achievement.

Requirements
It is earned when the player earns 15,000 or more points while playing the meta-game on Sierra 117. This Achievement gives 10 Gamerpoints to the player. The points can only be earned while campaign scoring has been tagged.

Tactics
Method 1 - Turn on the Thunderstorm and Fog skulls. Losing your motion tracker wont be a problem to use if you know the level well. The Thunderstorm skull won't make a noticeable shift in difficulty with the Brutes, but all of the grunts will be very good fighters, so be careful.Because they will be the rank of Ultra, they will shoot accurately, throw lots of grenades, and kamikaze a lot more. These two skulls should be all you need.

Method 2 - A very cheap, easy and noobish method is you turn on the Thunderstorm, Fog, Famine and Iron skulls on multiplayer. You can use a "dummy account" to survive while you go out there and kill people. In multiplayer, the Iron skull will make you go back to your last checkpoint unlike in single player where you restart the whole level. You get a 3x multiplier even though it's almost playing normally in single player. It is important that your "dummy" stays ALIVE and in a SAFE place. This method is best done on Normal difficulty.

Background
It is represented by a blue circle with a gorilla face in it.

The actual term "guerilla" comes from the Spanish word "guerra" and means "small war". Guerilla is referred to in this instance by the UNSC Marines Corps fighting in Covenant Loyalist occupied territory in the Republic of Kenya during the Second Battle of Earth in 2553.

There may be an additional play on words: guerilla sounds like "gorilla", a reference to the Jiralhanae, but the title most likely refers to MCPO John-117.

This may also refer to guerilla tactics because the Master Chief is moving in and out of the jungle using hit and run tactics

Trivia

 * The software used by Bungie to edit the map tags is named Guerilla.
