Unofficial fan site, not affiliated with Century Games. Numbers, unlock days and event rules change with patches and differ between states; treat them as rules of thumb and confirm in-game.

Recurring alliance events. Most are about coordination and attendance more than raw power. Each one has its own in-depth page.

**TL;DR:** Register on time, show up, follow your rally leads, and remember that **Foundry Battle troops recover afterwards**, so fight hard there.

## In-depth pages

- [Bear Hunt](https://wos.sheet.guide/en/guides/battles/bear-hunt.md): 30-minute rally event. The trap recharges about every **47.5 hours**. Joiners: **Jessie**, Jasser or Jeronimo in slot 1. Marksman-heavy troops: **10/10/80** once you have Gen 7+ heroes.
- [Crazy Joe](https://wos.sheet.guide/en/guides/battles/crazy-joe.md): 20 waves. **Waves 10 and 20** hit the Alliance HQ. Stay online for the elite waves (7, 14, 17). Defend Infantry-heavy. Reinforcing earns half points.
- [Foundry Battle](https://wos.sheet.guide/en/guides/battles/foundry-battle.md): ~6 days of vote, register and match, then a **1-hour** battle against one alliance. The most **Arsenal Points** wins. The Imperial Foundry is the big prize. No permanent losses: troops recover afterwards.

- [Fortress & Stronghold Battles](https://wos.sheet.guide/en/guides/battles/fortress-battles.md): Weekly within an **8-week season**; battles on Fridays. Control a building for **30+ minutes** to take it. **Fortresses** pay better rewards than Strongholds.
- [Canyon Clash](https://wos.sheet.guide/en/guides/battles/canyon-clash.md): Monthly 3-alliance battle: **60 minutes** on Thursday. **Fuel** powers every move. Save some for the Citadel. Up to 2 legions of 30 combatants + 10 substitutes.
