Attack of the Radioactive Thing

IW PC : available Xbox : available PlayStation : available

Sonova Beach, a small California beach town, in January 1953. Nuclear tests have covered parts of the town in radioactive blobs, and the actors land in a black-and-white creature feature hosted by Elvira, who takes over from Wyler as the announcer. The Crog-Zilla fires eggs that hatch Crogs, fast frog-like mutants, while the heavier Crog Brutes charge, blind and burrow. The map brings the Modular Atomic Disintegrator, which refills its ammo by absorbing Crog eggs, and four teleporters. It came with Absolution, the third DLC pack.

A game starts in the contamination tent, a military tent at the edge of town. The Hailstorm is on the wall for 500 points and the Hornet for 750, next to Up 'N Atoms and the Lost and Found box; the Life Ray, a piece of the map's main quest, also stands in the tent. A 750-point door next to Up 'N Atoms opens onto the Diner and the Drive-In screen, and another door leads to the Drive-In Theatre entrance. The enemies are zombies, Crogs on their special scenes, and Crog Brutes from around scene 12.

Attack of the Radioactive Thing First Room

The Attack of the Radioactive Thing First Room leaderboard on Zombie First Room Rankings tracks every verified run held in the starting room of Attack of the Radioactive Thing, on Call of Duty : Infinite Warfare. 37 records are listed here, and the best rounds on record are 24 in solo by Sovetskiy bober and 23 in 2 players by Red Death.

Attack of the Radioactive Thing is tracked outside the rankings: its records earn no ranking points, because no ranking takes it. It does carry a difficulty coefficient — solo 7.4 and two players 7 — which is what weighs its rounds in the ZFRR rating of the players who hold them.

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 Attack of the Radioactive Thing, 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

Infinite Warfare First Rooms are tracked in a single category, Fate Cards only: reach the highest round you can without opening any door or barrier, every round played in full, no glitch or exploit.

Fate Cards only means no Fortune Card is used; Directors Cut and Irish Luck are not allowed either, and neither are one-window strategies.

Full gameplay is required, with a clear proof of the category: the pregame lobby, the after-match lobby or the pause screen. 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.
