Containment is a Halo 2 multiplayer map. The Halo 3 map Isolation is partially based on this map.

Introduction

"Containment" was based off of the Sentinel Wall of the campaign level Sacred Icon. It is a large outdoor symmetrical map that is a "biological airlock" between the Flood-infected zones of Delta Halo and the "clean" zones patrolled by Forerunner sentinels. It is set in a fault between two snowy cliffs, and there are two massive Forerunner fortresses on either side of the map, acting as bases and also the barricades meant to defend against the Flood.

Topography

It is similar to Coagulation, in the sense that it's an open, hilly terrain. On each side is an old Forerunner ruin, acting each as a base. Each base, red and blue, has a large gate (resembling a ramp, and functioning as one until opened). About 300 feet from it, is a panel which opens each. This is used to get a vehicle inside, as you can go around through the caves, or you can jump the ledge without a vehicle. A classic example of Bungie's genius for creating multiplayer maps are the two fully functional gate switches and opening gates. There are two warthogs, two scorpions, and two banshees by default spawning. It is ideal for large, system link games or even xbox live games, about 6-16 people. Any number less than 6 players could result in a slow match.

The level may also remind you of the classic multiplayer level from Halo: Combat Evolved, "Sidewinder", being set in the snow and having a blue and red base. However, this map is very different from Sidewinder and is not a Sidewinder remake.

Tactics:

1. -Though there are normally only two sniper spawns (one at each base), stay hidden. Snipers favor this large, concealing landscape. Competent snipers can make quick work of an advancing group, due to the open nature of the level. There is an assortment of cover around (the variety of rocks sticking up; the small indent on the sides of the bases, etc.), but not enough for you to shoot it out with a foe across the course.
2. -Watch for the mines. They are incredibly devastating. Keeping this in mind, they can easily be used as a deterrent from a Warthog- the opportunities for traps are endless.
3. -The giant ramps open on each of the bases. This allows the Scorpion tank access to the inside.
4. -In CTF(Capture The Flag)if you are defending, always post a guard on top of the base. This is important as you do not want anyone jumping down from behind and stealing the flag.
5. -Don't underestimate the network of tunnels running throughout the level. A favorite of would-be snipers and rocket users, you can easily avoid the open space by learning to navigate these tunnels. Each base also has an entrance (on two sides) from this tunnel network- don't forget about it.
6. -The turrets are usually a bad decision. It's asking to be sniped or rocketed, and there's also a fair chance that you'll be killed by a vehicle.
7. -A good player will get a battle rifle and sniper rifle, go to the Banshee and fly it up to the top of one of the large structures sticking out of the cliff (in between the base and the bridges). From here you can snipe most of the other players on the map

• Containment was added to Halo 2 in the Bonus Map Pack.

Trivia

• It is called "The Great Freezing Plains of Blarganthia" in Red vs. Blue, and is visited in Season 4. The "Grunts" from Battle Creek are found working together defending the wall.
• There are 7 "pyramid-fusion coils" on the map.

Easter eggs

If you take a Sniper Rifle and look at the halo around the level near the sun base (the one with the orange yellow glowing buildings) you will see the face of Chris Carney, one of Bungie's developers, smiling. In the machinima series "This Spartan Life" one of the players gets an unlock and is trapped playing Halo 2 as the face.

Fortress

The two fortresses are large but have multiple ways in.

Ways In

• 1: The right tunnel.

• 2: The left tunnel.

• 3: The outside has four downwards walls, an attacker can climb up and then jump onto the fortress walls.

• 4: By air.

• 5: Via the gatehouse which opens the gate.

Tactics

NOTE: THIS IS FORTRESS TACTICS: FOR THE

• 1: Posistion a heavy turret vehicle (Gauss Warthog) at the tunnel leading to the base.

• 2: Have two men defend the gatehouse (Theres a portal from the fortress to the 2nd floor of the gatehouse. So you can get reinforcements)

• 3: The ledge outside of the fortress (Directly outside the walls), use it and also for wall climbers use an Energy Sword to surprise them and kill them.

• 4: Get a Scorpion on the diagonal gate.

• 5: Use a Spectre to transport defenders throughout the base.

Territories

• Bridge
• Red Cave
• Blue Cave
• Red Gate House
• Blue Gate House

Glitches

• If you fly a Banshee at the top of the map, you can hit an invisible wall. But if done at the correct angle, you go straight through the wall to a perfect sniping position. You can also boost a Spectre up the base walls, or, if you can waste a lot of time, jump up the walls slowly.
