The Irradiation Beta is a support power used by Russia and Latin Confederation from a Nuclear Converter that does as its name suggests by temporarily irradiating friendly vehicles with constant nuclear radiation that damages nearby enemies while the radiation field lasts.
The AI will cast Irradiation Beta on specific task forces that will be prepared and will regroup near the enemy base when Irradiation Beta is 70% ready, or roughly 1:30 minutes before it is ready.
- Irradiation Beta debuts in Road to Nowhere as usable support power. In this mission as well as in Trophy Hunter, Noise Severe and Heartwork, Irradiation Beta can be used freely without a Nuclear Converter.
- Throughout Act One, Irradiation Beta is also used by China in addition to Russia and the Latin Confederation in place of Pack Attack. By the time of Act Two, China upgraded their Irradiation Beta into Gamma.
- In the ground phase of Time Capsule, Irradiation Beta will be unlocked after Yunru reaches Helibunker. Its cooldown is decreased to 12 seconds.
- Chronologically, Irradiation Beta is unlocked in Thunder God.
