Part of the Alliance Series:

Quick Answer

Three separate alliance competitions, often confused:

Capital Clash runs inside the SvS warfare stage, from 10:45 to 18:45 UTC. It's hosted by the state that lost the preparation stage. A concentrated fight over the capital and the buffs that come with holding it.

Alliance Showdown uses registration and outpost occupation in the 1.25.700 revamp. It has its own preparation and reward rules.

Alliance Duel is seasonal warfare with opponent selection and an hour-long battle under its versioned casualty rules.

For live battles, follow the caller's role and march instructions. For Showdown, complete registration and review the event formation.

Overview

The alliance competition layer is where organised alliances separate from social ones, and it's the part of the game most likely to feel opaque to a newer player because it happens fast and it's coordinated in chat.

What you'll find is that your individual decisions matter much less here than your responsiveness. An average account that joins every rally promptly contributes more than a strong account that misses the calls.

Here's the practical framing: these events are your alliance's, not yours. Your job is to be available, be loud about what you can contribute, and do what the callers ask.

Capital Clash

The one people ask about most, because it sits inside the biggest event in the game.

When: inside the SvS warfare stage, 10:45 to 18:45 UTC. Warfare itself runs Saturday 08:45 to 19:00 UTC, so Capital Clash occupies the middle eight hours of it.

Who hosts: the state that lost the preparation stage. This is a deliberate piece of design — the losing state has the fight brought to it, while the winning state also carries a 15% healing buff through warfare.

What's contested: the capital and the buffs that come with holding it.

Why it matters beyond the fight: Capital Clash is the main source of Mercenary Influence, the material that feeds chief badges. Badges are worth roughly 332% health and lethality per troop type when maxed, and the influence to build them mostly comes from this one window. Skipping Clash month after month is the quiet reason plenty of accounts never get their badges moving.

What it means for you:

  • In a top alliance contesting the capital: this is the main event. Follow rally calls exactly.
  • In any other alliance: join rallies when called. That's a real contribution and it's the right ceiling for most accounts.
  • Developing account: shield if you're not participating, and don't wander into the contested area with marches out.

[!IMPORTANT] Winning the preparation stage matters for more than the healing buff. It also decides whose state hosts Capital Clash, which shapes the entire warfare window. That's a strong argument for scoring hard in preparation even if you never fight.

Alliance Showdown

The dedicated Alliance Showdown guide covers the 1.25.700 outpost revamp: inner, central and outer zones, occupation points, automatic assignment by Power and R4/R5 adjustments.

Register and check the submitted formation. Banking speed-ups is not a substitute for the combat entry. Compare alliance occupation goals with the separate solo damage ranking. Older three-lane instructions describe another format.

Alliance Duel

Use the dedicated Alliance Duel guide for opponent selection, building objectives and troop recovery. Version 1.20.00 specifies full recovery for eligible battles during the hour-long warfare window.

That does not mean every item spent is refunded or every unrelated attack is protected. Check the active rule, coordinate targets and stop when the protected window ends. Alliance Throwdown, in contrast, is the task-completion event.

How They Fit Together

Event When Scope
SvS Monthly: ~5-day prep, warfare Sat 08:45–19:00 UTC State versus state
Capital Clash 10:45–18:45 UTC inside SvS warfare Cross-state, capital contested
Reservoir Raid Weekly, Sundays, 1 hour Alliance versus alliance
Alliance Showdown Own cadence Alliance-scored
Alliance Duel During MIGO season, 3 stages Alliance versus alliance, 100% troop return
Infected Horde Every 2 weeks, ~40 min Alliance PvE

The pattern across all of them: preparation between events, participation during them. The alliances that win are not the ones with the strongest individual accounts; they're the ones where everyone banks resources and turns up.

F2P vs Spender

F2P accounts contribute most through reliability. Being available for rally calls, keeping a march free, and turning out consistently is worth more to your alliance than raw power, and it's entirely free.

Spending accounts carry the contested fights, particularly in Capital Clash where holding the capital comes down to who can sustain rallies. Rally lead investment pays off most here. See the hero tier list.

Common Mistakes

Confusing Capital Clash with SvS warfare. Clash is the 10:45–18:45 UTC window inside the wider 08:45–19:00 warfare stage. Fix: know both times.

Assuming the winning state hosts Capital Clash. It's the losing state. Fix: score hard in preparation to avoid hosting.

Having no free march during alliance hours. Can't join anything. Fix: hold one back. See the march capacity guide.

Skipping Alliance Showdown. It feeds advanced alloy for badges. Fix: turn out.

Assuming Duel protects every attack. Check the eligible battle types and warfare timer before committing troops.

Skipping Capital Clash and then wondering why badges never progress. Mercenary Influence mostly comes from here. Fix: show up, even as a rally joiner.

Leading rallies as a developing account. Feeding kills. Fix: join instead.

Wandering into contested areas unshielded. Fix: shield and recall marches if you're not participating.

Bunker and Facility ownership uses a separate event: see Fortress Fight registration, control and rewards. An announced State Merge also requires checking the reset map and the next challenge schedule.
