Outpost 25, an Omega Group research base in the A Shau Valley, Vietnam, on June 15, 1984, built on an old firebase to mine the Dark Aether. The map is split in two, a village that houses the scientists and the firebase itself, linked by a teleporter. Three Aether Reactors replace the power switch, and each is defended against waves of the undead.

A game starts in the village courtyard, where the Magnum hangs on the wall for 750 points. The enemies are zombies, Armored and Heavy Zombies, Hellhounds, Manglers, Mimics that pass for an item on the ground, and the giant Orda.

Firebase Z First Room

The Firebase Z First Room leaderboard on Zombie First Room Rankings tracks every verified run held in the starting room of Firebase Z, on Call of Duty : Black Ops Cold War. 52 records are listed here, and the best rounds on record are 90 in solo by x-tropical_kush, 53 in 2 players by Hicham-78Az, 53 in 3 players by Hicham-78Az and 38 in 4 players by x-tropical_kush.

Firebase Z counts in the No Support ranking, in solo and with two players. Its difficulty coefficient — solo 3.6 and two players 4.4 — multiplies every round reached here, and also weighs its rounds in the ZFRR rating of the players who hold them. Three and four-player runs are listed here and count in the rating only.

First Room is the purest discipline in Call of Duty Zombies: no Pack-a-Punch run around the map, no easter egg, no train through open ground. You hold the spawn room of Firebase Z, you keep the doors closed, and you push the round counter as far as the horde allows. Every high round, world record and personal best on this page is backed by its video and checked against the reference boards before it is listed.

Rules / Informations

Black Ops Cold War First Rooms are tracked in a single category, No Support: reach the highest round you can without opening any door, every round played in full, no glitch or exploit. In solo and with two players, these First Rooms score points in the No Support ranking.

No Support means the support items are not used at any point of the game: these are the scorestreaks, such as the Sentry Turret, the Chopper Gunner or the War Machine. Loading into Outbreak first to get the extended interaction range is allowed.

Full gameplay is required, and every player's point of view in co-op. Duplicating wonder weapons is not allowed. The health, the points and the round counter are never covered. The rules of each map are listed on its leaderboard.

Game versions and platforms

The version the game is played on is part of the rules. A run played on a platform or a client refused below is not listed, whatever the round or the time — and a run already on the board is removed from it.
