Powerhouse was formerly utilized to provide alternative power supply to the rural settlers nearby, but has now been repurposed to support the military war efforts. The map is primarily designed for 4v4 gametypes and appeared in the Grab Bag and Arena playlists during the Halo: Reach Multiplayer Beta.
In team modes, such as Team Slayer, both teams spawn almost equal distances from the Gravity Hammer and the Rocket Launcher. Most players will head towards the rocket launchers first. It you also choose to go for the Rocket Launcher, it is advisable to throw a grenade or two towards the rocket launcher to wound any players from the other teams that might have been going for it too, making for an easy kill.
The Gravity Hammer and the shotgun are the most valuable weapons to have. If you can, have one player get the gravity hammer, and the other get the shotgun. To round out your arsenal, both players should also have a mid-range weapon, such as a DMR. Once you obtain these things, it is a good strategy to camp it out in the big two story building at the back of the map.

- The map was known as "Settlement" at some point in development.
- Like almost all Halo: Reach multiplayer maps (excluding Forge World), the map has been repurposed and used in campaign, although the level takes place at night instead of day in the level Nightfall.
- Powerhouse's art style and environmental layout is very similar to that of Halo 3's High Ground multiplayer level.
- Near the red team spawn point, there is a spot on the wall that resembles the shape of a pig. This easter egg can be seen on the side of one of the staircases.
- If you drop down the waterfall to one spot on the rocks where you can't be killed by barriers then the location next to your radar will say "Vaya con Dios!" which means "Go with God."
- The map makes an appearance in the TV show Psych in the episode, "Not Even Close, Encounters." It can be seen at the end of the episode where Gus and Dennis are playing a split-screen multiplayer match in Dennis' office. This can also be seen as a goof as Gus tells Dennis to detonate the Pillar of Autumn, mistakenly referring to the last level of Halo: Combat Evolved.
- Originally there were shower heads in the Beta, however they were removed in the final game due to players getting stuck in the shower head's geometry.
