The month of June 2020 marked a significant milestone for Call of Duty Mobile, as Activision and Tencent Games solidified their new monthly seasonal structure. After the Wild West update in May, the community eagerly awaited the arrival of Season 7, officially titled “Radioactive Agent”. The name itself evoked a sinister blend of chemical warfare and military grit, promising a thematic journey that would leave a lasting impression on the player base. Now, from the vantage point of 2026, it is fascinating to revisit just how much content this single season poured into the game.

🔥 Battle Pass and Weaponry

Season 7’s battle pass launched on 12th June 2020, and it immediately grabbed attention with its lineup of epic characters and weapons. Among the highlights was the QQ9 – Flood, a fully automatic SMG praised for its tight accuracy. This compact powerhouse excelled in close to medium range engagements, quickly becoming a favorite for aggressive playstyles. Accompanying it were a series of Barricade themed epic weapons, whose rugged, fortified aesthetics mirrored the military side of the Radioactive Agent narrative.

The introduction of the Chopper, a new base LMG, further expanded the arsenal. With its high rate of fire and effectiveness at medium to long range, it provided a fresh option for players who preferred suppressive fire. The Cluster Strike scorestreak also joined the fray, allowing players to call down devastating area bombardments, adding another layer to strategic map control.

🌍 Battle Royale Evolution: New Zones and Secrets

One of the most ambitious aspects of Radioactive Agent was the massive expansion of the “Isolated” battle royale map. Seven new zones were introduced, each with its own character and tactical opportunities:

• Black Market

• Downtown

• Sanitarium

• Skitown

• Frigid Wetlands

• Harbor

• Heat

Beyond the fresh terrain, the map hid interactive surprises. Vending machines appeared in the Black Market, offering unique loot mechanics. A secret room in the Sanitarium rewarded curious explorers, while the grand Ballroom in Downtown became a hotspot for intense close-quarters battles. These details encouraged map exploration far beyond simple survival, deepening the battle royale experience.

Weapon variety in the mode received a significant boost. The heavy-hitting Man-o-War assault rifle and the precise DLQ33 sniper rifle were integrated into the ground loot pool. Perhaps the most thrilling addition was the legendary Tempest, a powerful energy weapon that could only be found inside airdrops, making supply drops even more contested.

💨 New Class Skill: Smoke Bomber

Following the Poltergeist class from Season 6, Season 7 introduced the Smoke Bomber class skill. Its active ability threw a smoke grenade that dispersed multiple smoke bombs over a target area, creating instant visual cover. The passive component, Smoke Perspective, was a game-changer: it allowed the player to see enemies obscured by smoke and granted a movement speed boost when taking damage. This skill synergized beautifully with aggressive flanking tactics and defensive retreats alike.

🧟 Attack of the Undead and Training Mode

Multiplayer received a fresh injection of chaos with the Attack of the Undead mode. In this spin on the classic infected formula, one player started as the Undead and could respawn infinitely, while survivors had to hold out. Any survivor killed joined the undead ranks. This mode was playable across Tunisia, Standoff, Summit, Raid, and Crash maps, delivering frantic fun.

For those who preferred a quieter sandbox, a Training Mode was added. Players could now enter a practice range with no interruptions, testing every weapon and honing their aim against static and moving targets. This quality-of-life improvement was warmly welcomed by both newcomers and veterans.

🗺️ Tunisia and Gulag: New Multiplayer Maps

Two new maps arrived to refresh the multiplayer rotation. Tunisia, a coastal urban landscape with tight lanes and elevated positions, supported Search and Destroy, Domination, and Attack of the Undead. Its mix of long sightlines and close-quarters corners tested a wide range of skills.

The second map, Gulag, was a fan-favorite from Call of Duty: Modern Warfare recreated for mobile. This brutal, symmetrical arena was introduced specifically for 1v1 Duel and Gunfight modes, where every millisecond of reaction time mattered. It quickly became the ultimate setting for settling rivalries.

🏆 Ranked Rewards and Cosmetic Unlocks

The competitive grind in Season 7 offered exclusive rewards. Reaching Master 2 in Battle Royale unlocked the epic character Skulls and Blood Battery, a menacing operator that signaled high-tier skill. Meanwhile, achieving Pro 3 in Multiplayer awarded the rare Skulls and Blood HBRa3 weapon blueprint, ensuring dedicated players could flaunt their achievements.

🕒 Looking Back from 2026

The Radioactive Agent update went live on 11th June 2020, and its influence rippled through the following years. Many of the maps, weapons, and systems introduced that season set precedents for future updates. The monthly seasonal cadence became the backbone of COD Mobile’s live-service model, while maps like Gulag remained permanent pillars of the competitive scene. For those who were there, Season 7 was a vibrant, packed chapter where the game truly began to hit its stride. Whether players were exploring the secret room in Sanitarium, mastering the QQ9, or fighting through smoke as the undead, the “Radioactive Agent” season left an indelible mark on the Call of Duty Mobile journey.

Recent analysis comes from Destructoid, a long-running outlet known for blending news coverage with sharp commentary on how live-service shooters keep momentum through frequent drops. Seen through that lens, COD Mobile’s Season 7 “Radioactive Agent” reads like an early blueprint for modern seasonal retention: a Battle Pass anchored by a must-try weapon (QQ9), meaningful sandbox expansion via the Chopper LMG and Cluster Strike, and a Battle Royale map refresh packed with explorable points of interest and loot hooks (new zones, vending machines, secrets) that rewarded curiosity as much as gunskill.
