Lockout

Lockout is a Halo 2 multiplayer level, and has been remade into the Halo 3 multiplayer map Blackout.

Description
Lockout is theoretically an old research laboratory designed by the Forerunners. In the icy mountains of Delta Halo, the only way you can get a good view of Installation 05 is by Sword Canceling from down below to someone jumping on a pillar above, flinging you to the top of the level.

Once atop the huge structure, drop down at the first part and keep walking down the slope until you reach the back. There, the material of the floor seems to turn bluer, and if you look at the landscape, you see a lot of snow, mountains, and the Halo.

Gameplay
This map is heavily favored by MLG professionals and skilled snipers. The superbounces on this map make for interesting gameplay and tactics.

It is usually played solely as a close quarters map because of the nature of the course and map default spawns. It's no less uncommon to have three-man matches than to have ten-man matches; it's simply guaranteed to be more chaotic as more members enter the game.

A small room exists on the bottom floor with small, damaged, Green-Glowing chambers and at the end there is a Gravity Lift back to the surface.

Lockout consists of three levels. Most of the fighting occurs around the center of the map, either the upper or lower level.

The towers abutting the center arena are used to get a better view of the upper level, as well as surprise attacks for people beneath them. There is a room with a gravity lift on the lower level that takes you up to the upper level, near the center.

Lockout is, overall, a very straightforward map hence its popularity among MLG players, and the map default weapons are generally close-quarters minded with longer range weapons acting as power selections, if used correctly.

Territories

 * Lift/Top of Lift Tower
 * Centre/Underneath Centre
 * Sniper Tower (right side when coming up Gravity lift)
 * BR Tower (left side when coming up Gravity lift)
 * Elbow (connects the lower lift room to Sniper Tower)

Tactics

 * If playing CTF, a Brute Shot jump will carry a player from the base at the top of the BR tower to the elbow catwalk; unless the player has uncommonly good aim with such jumps, the only way to avoid dying is to lunge at a player on the catwalk with the energy sword.
 * There is a common Superbounce on this map, used to get on top of the Gravity lift tower. Be aware of its existence and predominance in the game. Snipers will use it ad infinitum, and are hard to pick off due to the natural cover that it provides.
 * There is also a lesser known Superbounce on this map, used to get on top of the Sniper Tower. Not everyone uses it, but make sure you know that it is easy and probable that you may run into someone who can Snipe you from up there. Also, if hiding in the right spot, it is easy for anyone to avoid danger, so the best way to eliminate someone using this bounce is with a Sniper rifle, someone else or you super-bounce up there, or plasma grenades. It is easy to be a Juggernaut on the battlefield when up there. You can also butterfly to any high location.
 * In the bottom floor, underneath the center panel of the top level, you can hide in the corners and remain stationary, and surprise and kill anyone whom walks in with a shotgun. This can be countered by clearing the room with a grenade before entering it; if anyone survives the blast, you will hear static from the player's shield.
 * In Sniper matches, it is common practice to stand at the far end of the course, on the lower level, and snipe people across the level. Since the hall is continuous, there isn't much chance to react to a good sniper. This has given this "hallway" the nickname "Sniper Alley".
 * The default place for the Sniper Rifle to spawn is at the top of the Sniper Tower. You can easily kill anybody standing up there trying to snipe people by blowing up the explosive barrels at the back of the platform. This will also kill anyone in the turret on the platform.
 * By default, the Battle Rifle spawns on the top section of the Gravity lift tower, and on the tower opposite the Sniper Tower. Remember it, since in Map Default games, mostly populated by Dual wielding, distance can give you the win.
 * A good way to kill an enemy is to ambush them when they float up from the Grav-Lift. But make sure you hide near the "drop-down-holes" and when they're just about to touchdown, assassinate them.
 * Be constantly alert for the player wielding the Energy Sword or anyone trying to take it from you.
 * If you don't have the Energy Sword, use the shotgun. If the sword-wielder lunges, you have a fraction of a second in which you can kill your opponent with a single blast to the chest before your opponent kills you.
 * A good player can use only the Sniper Rifle and the sword and win with a score more than double of the player coming in second. Stay on the tower that the Sniper Rifle spawns on.  From there, you can hit people all across the map. Just remember to alternate at different times what level of the tower you are on to avoid being sniped back. If anyone tries to invade your tower, slash him or her.
 * When traveling, search the room you're walking into. Use your motion tracker and slightly angle yourself to have better luck getting someone ambushing you. If you have frag grenades, throw one (two if you are entering a large room) to kill any enemies in the room or to alert yourself to their presence.  In team games, always keep your teammates posted on where you are to prevent being betrayed in this way.
 * When you're playing on this map, if you use a rifle or a single dual-wielding weapon, don't enter enclosed spaces. In close-quarters fights, shotguns, the Energy Sword, and dual combos nearly always win against rifles.
 * Remember what is above and below you. You can take vertical shortcuts and avoid being ambushed in this way.
 * The first and second floors of the Sniper Tower are the hottest section of the map. Avoid going here unless you are sure that all resistance has been eliminated.  There are two good ways to attack players on the Sniper Tower:
 * Crouch-jump from below the Sniper Spawn to the landing of the ramp just below if you have a close-quarters weapon or a dual combo
 * If you have a rifle, attack from the top of the BR tower.

Super Jump
To do the Super Jump, go to the BR Tower and face the path entering or exiting and take a left. Stop before the next doorway and crouch where the little tower sticks out of the wall and walk towards it until you can let go of the control stick and you are still crouched. From the crouch, Jump to the ledge and land on it and walk forward a small amount and jump and land right before the crack on the ledge. (Note that you must hold the stick forward while jumping)

To do the Super Jump on top of the Sniper Tower, go behind it and crouch in the corner you find where the platform corners and the rock wall is present. Jump out of there and face down the ramp you come UP. You notice that there is debris and dirt at the bottom, Run jump a little late and land on that debris. If you land on the right spot you will go on top of the sniper tower, if done wrongly, there is no real danger and you can just try again. You CANNOT fall through the map with this bounce.

Trivia

 * This is the map that the Ghost of Halo sightings started on because of the infamous Ghost of Lockout. It is also one of the most common Ghost sighting maps for Halo 2.
 * There are fourteen Forerunner Energy Cores on the map. Fourteen is a multiple of 7.
 * The Halo 3 map Guardian is similar to Lockout in terms of design because they both share the 'green shotgun hallway', two main central levels of the map and four bases branching off of the main section. They also both have a main large gravity lift. These similarities have been confirmed by Bungie to be purposely put in the game.
 * Lockout has been remade as Blackout in the Legendary Map Pack in Halo 3.
 * The beings in the green, cryo-like chambers are said to be infected Forerunners, though if you look closely, they resemble Spartans wearing Mark V armor. If you look at the particles on the tanks, they look like the Flik'ta from the Marathon series.
 * The alleged infected Forerunners in the cryo-tubes can also be seen on the level The Oracle in the chamber where you first encounter the Flood on the level.
 * One of the green chambers are open, which could mean something escaped or broke out of the chamber, similar to the broken cases on Cold Storage.
 * Lockout, in polls, tends to be thought of as the most popular multiplayer map in Halo 2.
 * If one looks at the mountains, the texture looks like it has a face on it.
 * The bottom level of the Sniper Tower is often referred to as the "suicide room" because this room is often grenade-spammed in the fighting for control of the Sniper Tower; entering this room nearly guarantees death in games of four or more players. Another name for this room is the "panic room".
 * Lockout is referred to as a very good level for playing Juggernaut.
 * Lockout's overall design and architecture appears to have been inspired by the final area that the player approaches before entering the gondola on the level, Quarantine Zone, due to the architectural designs being almost identical.
