What is it?
A daily event of timed phases, each scoring a different category (building, research, training, hero power, and so on), handing out milestone chests as you cross point thresholds. Confirmed Mechanic
When does it happen?
Daily, in timed phases through the day. Update-Sensitive — confirm the current phase schedule in-game.
Who can start it?
Individual. Every player.
How does it work?
Each phase scores one category — do that activity during its phase and it fills the milestone chests. The real lever is stacking: many actions score Arms Race and another event simultaneously.
What should I prepare?
Hold completions, stamina, and speedups so you can release them during the matching phase rather than whenever they come up.
How do we win?
Align your big actions with the phase that scores them, and stack with the VS day and Zombie Invasion stamina windows so one action scores in two or three events at once. Corroborated Strategy
Common mistakes
- Spending actions outside their scoring phase.
- Not stacking with the VS day and zombie windows.
- Treating the events as separate when they overlap.
Leadership protocol
Call the high-value phase and stamina windows so the alliance stacks Arms Race with Zombie Invasion and the VS day together. Leadership Protocol
Arms Race rewards timing, not extra effort. The same speedups, the same stamina, the same builds — released in the right phase — score Arms Race, your VS scoring day, and Zombie Invasion simultaneously. Stack the windows and one action pays three times.
