Core problem: As defenders in Expedition, you do not need a clean wipe of every attack. You need to drain attacker Momentum and keep Headquarters from being secured (built out or bombed) long enough that they stall. The Support Objective is the swing point most teams lose on. Recapture it at the right time or attackers get a forward spawn, support weapons, and extra Momentum.

1What You Are Actually Defending

Headquarters (permanent if secured)
Attackers must capture then secure it
Once secured (build 3 structures or plant and detonate a bomb), that sector is gone. You cannot recapture a secured HQ. Defenders have no Momentum bar. You win by killing attackers (each death costs them 1 from a 100 start), holding HQ, and letting Foothold expire if they dump all Momentum.
Support Objective (never permanently locked)
Whoever holds it gets spawn, weapons, Momentum
Never permanently locked. Whoever holds it gets a spawn, support weapons (Toffee Apple mortar), and attackers also get Momentum. You can and should steal this back.

3Support Recap Timing (The Decision Most Teams Get Wrong)

Do NOT send the whole team off HQ the instant Support flips.
  • Recap Support when attackers are mid-build or mid-plant on HQ and you can peel 4-8 players without collapsing HQ.
  • Recap Support when they have already planted a forward spawn or mortar on Support and are feeding from it.
  • Recap Support when your Momentum drain is stalling because they keep respawning 20 seconds from HQ.
Recap Support to delete their spawn and mortar, then immediately rotate bodies back to HQ. Holding Support forever is optional. Denying it during the secure window is not.

4Key Decision Points

SituationChoice
HQ contested, Support just flippedPeel a small recap group only if HQ still has a screen. HQ secure = sector lost.
Attackers building 3 structuresPrioritize interrupting builders over farm kills in no-man's-land.
Bomb plantedDisarm first. Kills second.
Support has mortar and spawn, HQ is stableRecap Support now. That spawn is what keeps their Momentum alive.
Your team is dying 1-for-1 on open groundFall back to prepared positions. Trades favor attackers if they still hold time.

5Common Mistakes

Community consensus: hold HQ, murder the shovel and bomb, recap Support only when it is feeding their secure attempt, then snap back. Delay wins more games than a perfect hold.
