Chandelier Emergency Sortie: chamber and cooling route

YOUR FIRST MOVE

When the barrel opens, enter from the front and fire at the chamber. Exit through the side gaps. After the first chamber phase, attack backup cooling in the tunnel under the cannon, then return to the chamber to finish.

Follow the exposed objective, not just the score opportunities

simonsOG’s original post describes one successful destruction and gives the sequence below. Multiple commenters describe trouble reaching the core; a large personal score can still end in a failed team sortie.

  1. Open barrel / first chamber. Enter the barrel from the front while it is open and concentrate fire on the chamber. The source recommends guns against the large targets.
  2. Leave without deliberately crashing. The author describes yawing out through the barrel’s side gaps. Give yourself room to line up the exit instead of arriving with no escape plan.
  3. Backup cooling. After the first chamber phase, watch for the cooling targets. The reported entrance is below the cannon, low between the red structures in front. The post also describes a rear entrance.
  4. Final chamber. Return to the chamber objective when that phase becomes active. In the source’s account, destroying it ends the sortie.

Follow the target markings and radio calls in your actual match if they differ. The report does not provide a full timing diagram or coordinates.

Bring a plan for the chamber and the tunnel

Before launch, check whether your loadout can contribute to the exposed core and ground targets. The discussion criticizes teams that bring only long-range air weapons and spend the entire fight shooting outside targets. An aircraft you enjoy in Assault may need a different weapon choice here.

During the run, prioritize access to the objective. Hitting SAMs and anti-aircraft defenses can raise personal score, but it does not replace damage on the chamber that gates progress. Assigning one confident attacker to cooling while others are ready for the next chamber is a coordination suggestion from the source, not a requirement to use a particular aircraft.

Diagnose a failure before changing the whole build

  • Only fired from outside? The core’s position is the first issue to check; the post says to enter the open barrel.
  • Repeated collisions? Practice lining up the side exit. Losing the aircraft consumes time you could spend on the active target.
  • Lost the cooling phase? Look below the cannon and identify the front or rear tunnel entrance.
  • High score, sortie still failed? Check whether the team finished the required chamber damage.

The author estimates substantial sustained fire for the final phase. That is not a verified HP value or a one-minute kill requirement. A commenter proposes waiting for a late enemy wave to chase S-rank; that is a separate, unverified ranking tactic, and is not part of this clear sequence.

If this mission is never offered to you, start with Emergency Sortie availability. Campaign Mission 28 is a different encounter.
