Deadlock

Deadlock is a Halo 5: Guardians multiplayer map created from the Forge map Alpine. It was released on November 18, 2015 as part of the Battle of Shadow and Light update. The map is a mostly faithful remake the Halo 3 multiplayer map Standoff and is set in a UNSC research base near a rocky cliff face.

Layout
Deadlock's layout is highly faithful to its predecessor's, with much of the map's geometry being identical. The map features two dug-in bases at either end of an open, hilly field with large boulders for cover, and is best suited for high player counts and base-related game modes such as Capture the Flag and Strongholds. Combat centers around long sight-lines and light vehicles, with a rush for anti-vehicle power weapons along the middle of the map.

The map differs from Standoff mostly in weapon placement. Like before, the Spartan Laser is the central power weapon, with a Warthog, Ghost, Active camouflage powerup, and turret emplacement available at each base. However, the missile silos at the left and right sides of the map now add two more power weapons to the mix: the Rocket Launcher and Railgun. Additionally, at the top-back portion of each base is a Hydra launcher. The Mongoose available to each team has also been upgraded to a Gungoose. In terms of map geometry, the two most notable differences are the removal of the large silo doors behind each base and the addition of small satellite dish platforms at diagonal ends of the map's center which provide a high vantage point. The switches that control each base's bunker window and secret entrance are reversed from how they were on Standoff. They are open by default and the switch must be activated to permanently close them. However, in CTF the bases are still closed by default, and the switches must be activated to open them.
