Lockout

Lockout is a Halo 2 multiplayer level.

Background
It is supposedly an old research lab for the Forerunners. In the icy mountains on Delta Halo, the only way you can get a good view of the ring 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 more blue, and if you look at the landscape, you see a lot of snow, mountains, and the Halo.

Gameplay
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 (possibly Flood Stasis Chambers, one of which is open) and at the end there is a Gravity Lift back to the surface.

Basically, Lockout consists of two levels; a higher level and a lower level. Most of the action centers around the center of the level - either the higher or lower level.

The towers abutting the center arena are used to get a better view of the higher level, as well as surprise attacks for people beneath them. There's a room with a Gravity lift on the lower level which takes you up to the higher level, near the center.

It's overall a very straightforward map, hence its popularity with all duels, and the map default spawns are generally close-quarters minded.

Territories

 * Lift/Top of Lift Tower
 * Center/Underneath Center
 * Snipe 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

 * 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 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 superbounce up there, or plasma grenades. It is easy to be a Juggernaught on the battlefield when up there.
 * Dual wielding is very popular on this level.
 * 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. Obviously, this has also been rehearsed infinitely, so don't hesitate to chuck a grenade or two in the room before you enter it. Also, check the corners from an approaching hallway before running in.
 * 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, melee them at the back.(Pray they don't look back or left or right and just look totally "front" until they touchdown.)
 * If you don't have the Energy Sword, watch out. In the multiple close quarter fights you'll get into, the Energy Sword wielder will usually win.  Try using the Shotgun if you don't have the sword.
 * 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.  Anyone tries to invade your tower, slash them.
 * Noob combos are totally acceptable here if you find yourself facing better players. Just watch out getting the Plasma Pistol because you're exposed and standing beside a fusion core.
 * 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.

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 SuperJump 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 by the way.

Trivia

 * The Ghost of Lockout is said to haunt the level.
 * It might remade into Moonlight Sonata (Level)
 * There are a fourteen Forerunner Fusion Coils on the map, an obvious Seven reference.
