*"Lead the Marines in an all-out offensive on the control room."*

**Assault on the Control Room** is the sixth mission (fifth in a straight playthrough) of the Installation 04 Campaign in *Halo SPV3*. After Echo-419, enters into a tunnel within Installation 04's system, John-117 must fight through Covenant Forces and reunite with UNSC forces to find Halo's Control Centre. Upon reaching the control centre and discovering some of Halo's horrible secrets, Cortana tells John-117 that Captain Jacob Keyes is walking into a trap.

## Overview & Background

The whole mission takes place in a snow covered canyon which is entirely secured by the Covenant. The objective is to fight through Covenant forces, alongside Fire Team Zulu, and locate Halo's control room.

Most of the layout remains the same, but some of the repeated rooms from the original game have been cut. This is the only environment in the Installation 04 Campaign where original play spaces have been removed, which was done to make capacity for the newly added areas.

The areas in question are an elevator that leads to a small room, which then opens up to an extremely large indoor cavern section. This is largely a vehicle area, and as such, a second tank is available. Hard light bridges must be crossed over the gigantic chasm, which brings players to a large winding tunnel part, the same type of tunnel as seen in Halo.

After this, players ascend from the tunnel in a newly added large canyon section. This area leads up to the original control room pyramid from *Combat Evolved*, and was designed to be a more dramatic "assault" on the control room.

## Loadouts

There are five loadouts available for the player to choose at the beginning of the level:

 Grenadier
 Saboteur
 Marksman
 Demolitions

## Gameplay Information

As stated above, some of the copy and pasted rooms from *Halo: CE* have been deleted. The ones that remain are mostly stealth sections.

Unlike the original level, the Banshee is drivable in this mission, if the player can hijack one. The Scorpion tank from *Halo* has been replaced with the Grizzly tank, a vehicle from *Halo Wars*. In a straight playthrough of the Campaign, if the tank survives until it can go no further, it will still be there later on in Two Betrayals as a Cross-Map Unlock. In the new areas, a second Grizzly is available, alongside a Fuel Rod Wraith as an alternative.

Covenant dropships that were cut from *Halo: Combat Evolved* have been reincluded here. Honor Guard Elites are encountered in and around the control room pyramid. Extra Marine reinforcements were added in the last section to assist the player.

## Developer Information

The final canyon containing the control room pyramid has been massively expanded. This was done by peeling back the far side with the waterfall, and combining it with a map design dubbed by the SPV3 Dev Team as the "cake", short for "cakewalk". This is an environment that was first developed by one of the *SPV3* modders back in 2009. The initial idea was to incorporate one of the large bridges from *Halo*'s multiplayer into a natural terrain. After going through many iterations, it was used in the mod for the last section in this mission, being laid out as a tank section up to the control room.

## Trivia

* There are 18 terminals scattered throughout the level.
* Despite being the only environment from *Combat Evolved* where original play spaces were cut, with the new areas, it still takes considerably longer to complete this mission and Two Betrayals than it did in *Halo*.
* This is the first mission to feature Spec-Ops Covenant, namely Spec-Ops Hunters.
* This mission also introduces the Fuel Rod Wraith for the first time.
* This is the only level in *SPV3* where the unfinished Mantis vehicle can be spawned and piloted, via the Mantis Skull Easter egg, only found on Legendary or Noble. This feature was once present in Halo and The Silent Cartographer: Evolved, but it has since been removed from those levels.
