Season 1 Radiated Land and the γ Pathogen

Infection prevention and treatment

Most stacks you take are avoidable if you treat Virus Resistance as a gate, not a bonus, and if your alliance treats infection as a daily job. Use this playbook as a loop, not a one-time setup.

1. Raise Virus Resistance before you hunt above your weight. The Virus Lab is the building that increases resistance, and it unlocks at Base level 10. If a monster’s Virus Resistance requirement is higher than yours, there is a chance your troops become infected, and the number of stacks follows the resistance gap. Skip those targets until the Lab has caught up. Unlocks and upgrade order are in the buildings guide.
2. Stay out of Contaminated Zones until you are ready to accept stacks. Fighting monsters there always causes infection, regardless of Virus Resistance. The same is true of special infected monsters. Treat those marches as a planned spend, not a default farm route.
3. Watch what you bring home. Troops can carry up to one-quarter of your Base’s γ Pathogen stacks on an expedition. Returning infected troops apply the same number of stacks to your Base. In commander-versus-commander fights, all stacks the winner is carrying transfer to the loser. Losing in the Capitol or Battery also adds stacks.
4. Treat before the storm, not after it peaks. A γ Pathogen Storm runs at 12:00–13:00 on most season days and periodically adds stacks to every commander in the warzone. Higher Storm Levels raise how often that happens and how many stacks you gain. Ask allies to send Recon Aircraft before that hour, and send yours in return. One aircraft reduces 2 γ Pathogen stacks, or grants 2 Antibody stacks once you have no pathogen stacks left.
5. Request a cure, or mark yourself so ally cure is off, if you need to control who treats you. Keep going until pathogen stacks are gone, then bank Antibody (up to 50). Being infected again while you have Antibody spends those stacks first.
6. Do not sit at a full 100 stacks. Heavy infection slows Farm, Foundry and Oil production by 15%, cuts wounded healing speed by 25%, reduces hero damage by 5% and soldier morale by 5%. If the outbreak countdown finishes, your Base infects nearby commanders with one-third of your stacks. Get treatment before that timer ends, both for you and for the people parked next to you.

Class skills that change this loop — Healing Expert, Infection Spread, γ Pathogen Assault and γ Pathogen Boost — are in the professions guide. A base-skin skill named Gamma Taint can also apply stacks to non-allied players near your Base, on a cooldown.

Virus Resistance

Current Virus Resistance is measured against the demand on a target. The Season Weekly Pass also grants Virus Resistance +250. Resistance at each Lab level is shown on the building itself.

Stack caps, named states and Antibody

γ Pathogen stacks can reach 100, and you get a warning at that cap. After you have no pathogen stacks left, further ally treatment builds Antibody stacks, up to 50. The more pathogen stacks you have, the longer the negative effects last; higher Antibody lasts longer too. Super Antibody State raises soldier morale by 5%.

Name	Effect
Ecological Contamination	Farm, Foundry, and Oil Extraction Well production −15%
Viral Mutation	Wounded Healing Speed −25%
Toxin Erosion	Hero Damage −5%
Panic Spreads	Soldier Morale −5%
γ Pathogen Outbreak	When the countdown ends, the Base releases the γ Pathogen, infecting nearby commanders with 1/3 of your Base’s stacks
Super Antibody State	Soldier Morale +5%

When a Base detonates in a γ Pathogen Outbreak, nearby commanders are infected with one-third of that Base’s stacks.

γ Pathogen Storm schedule

Storms form at peak activity and affect all commanders on the World Map. They run at 12:00–13:00, with Storm Level rising across the season:

Storm level	Season days
1	1–6
2	8–13
3	15–20
4	22–27
5	29–34
6	36–41
7	43–48

There is no storm listed on season days 7, 14, 21, 28, 35 or 42. The 12:00–13:00 times are clock times, not a statement about your device’s time zone.

Clear Radiation Sources

Clear Radiation Sources is a two-part event: transporting Immune Protein to clear radiation at the Capitol, and fighting Giant Mutant Lizards that march toward it. Those are separate actions with separate daily caps.

• Radiation clearance: you can clear radiation sources 10 times per warzone each day, and 40 times in total if you also help other warzones.
• Giant Mutant Lizard attacks: you can attack 5 times per warzone each day, and 20 times in total if you also help other warzones.

Other rules for the event:

1. The Capitol has been contaminated by radiation. Commanders dispatch troops to transport Immune Protein and remove it.
2. During the event, 1 Giant Mutant Lizard appears daily in a corner of the map. It crosses cities on its way to the Capitol and attacks cities along its route.
3. The lizard cannot be attacked while moving. It stops for 4 hours only when attacking a city, and that is the only window you can hit it.
4. When a lizard attacks a city, members of the occupying alliance can garrison the city to defend it. Successful defenses also reduce the lizard’s HP.
5. If the lizard is not defeated while stopped at a city, it moves on to the next city and reduces the Capitol’s clearance progress by 1.
6. A total of 4 Giant Mutant Lizards spawn in each warzone during the event.
7. When the warzone reaches 100% clearance progress, enter the event page to claim the completion reward.

Clearing radiation or fighting the lizard costs 5 stamina and grants 100 points each. The lizard waits 15 minutes between city attacks, and a successful defense also deals 10 durability loss. Event tasks include taking part in radiation clearance, cumulative mutated-lizard kills across the season group, and servers in the group that have completed clearance. Task rewards include 50 Stamina, resource chests, UR Omni Hero Shards, recruitment coins, Uranium Crystal 10,000 items and diamonds; exact counts depend on the task.
