Crossfire is a multiplayer map in Half-Life. It was added to the game in patch version,[2] which was released on January 13, 1999.[3] The official Half-Life: Opposing Force version of the map was released on December 6, 1999.[4]


The building complex around the central yard.

Crossfire is meant for large groups of players.[2] The map is characterized by lengthwise symmetry and consists of two main areas: the building compound with a central yard, and the "Satellite Operations" bunker near a double helipad. They are connected by several passageways, including a long corridor in the middle of the map. The former area puts emphasis on vertical play, featuring three distinct planes, while the latter location is more heavily focused on horizontal combat. With spawn points located entirely within the building complex, and with the map's hallmark being the button inside the bunker that launches an airstrike killing everyone caught outside, Crossfire incentivizes venturing out of the starting area.

Comprised of numerous rooms and hallways, the building compound revolves around close quarters combat, with the only open area being the central yard, from which most of the passageways to the bunker can be accessed. This location offers a very large assortment of weapons, as well as health and Suit Chargers, Medkits, Batteries, and Long Jump Modules, but the ammunition for them is somewhat limited. Lifts are the main mean of travelling upwards, while balconies and large windows allow for a quick getaway from the higher floors. The side of the complex facing the bunker both features numerous exits from the area and provides plenty of cover against the bunker's defenses.

The largest open area in the map, the raised double helipad, is reachable by one of the two ladders and the two ramps, or by jumping from a higher elevation. It is here where the entrance to the bunker can be found; the ladders of its two cannon towers are also accessible from here. At the base of each tower is located a guard post with an embrasure and a supply of Crossbow belts, connected via a chute to the cannon emplacement above. The bunker's lobby is equipped with four health Chargers, the use of which requires turning one's back to the helipad area. Hallways leading from the lobby provide access to the guard posts as well as two supply rooms with large quantities of ammunition for various weaponry. They are also connected to the airstrike hub situated at the back of the bunker.

As the button in the hub is pressed, sirens located throughout the map start sounding, and soon the bunker's main entrance door begins to shut. When it is completely closed and the guard posts' embrasures along with the chutes are blocked off, the airstrike commences. After a few seconds, each person caught outside the bunker is instantly killed as every player's screen flashes white. The airstrike cannot be called in again until three minutes pass from this moment.

Behind the scenes[edit]

An inaccessible room with a Crossbow, Medkits, and Batteries, illuminated by blue lights can be found in the map using the noclip mode. It could be entered up until the last minute before Crossfire's release. When the decision to remove it was made, only a very minor change to the level was permitted. The solution was to disable access to the room rather than deleting it.[5] Dario Casali's signature can also be found using the noclip mode.

As the skybox texture is improperly defined in the map file, Crossfire uses either the one from the last loaded map or the default "desert" texture.[6]

Crossfire spawned a follow-up map for Half-Life called DoubleCross,[7] and inspired the Half-Life 2: Deathmatch map Run Off.[8]


Valve has stated that Crossfire is their favorite teamplay map.[9]
