API 1 package, version 1.0.1. Enable it in Mods at the main menu and apply the selection. The normal dependency selection also enables iron_coast_scout, iron_coast_turret, iron_coast_boss_2, iron_coast_music, pulse_cannon, seeker_swarm, ion_lance.

Mission iron_coast_mission_2:mission_02: Iron Coast S1 M02: Tidal Relay. Destroy all three relays and the Relay Warden. Required ground objectives remain reachable; escaping optional aircraft never counts as a kill. Elapsed time alone does not finish the mission.

Scheduled spawn totals for Training / Rookie / Veteran / Elite are 29 / 40 / 51 / 62. These are enabled scheduled entries, not simultaneous live-enemy counts. Groups can overlap when earlier enemies survive.

Align the forward guns with required targets while moving around incoming shots. If carried, select Field Repair or coolant with Cycle and use Special: they restore 25 or 30 energy respectively and consume a real item. Shop purchases and refills still cost credits.

Equipment supplied by the mission

A temporary Pulse Cannon trial is supplied when it is not already carried and an inventory slot is available. It fires automatically with the primary Fire control and is returned after the mission.

Validation and history

See the current Iron Coast retune results and limits. Package-local acceptance reports, validation results and retained test sources describe pre-retune 1.0 behavior unless a result explicitly identifies the newer package and runner. They remain historical material, not current playthrough guarantees.

Rebuilding the briefing

Run python3 art/build_cinematic_briefing.py from this package directory (Pillow required). It verifies the unchanged cinematic master and rebuilds the exact SD/HD filenames referenced by content.json; the prompt and provenance are beside the master in art/. This artwork update changes package hashes; existing pilots use the normal changed-mod confirmation, with stable IDs and saved equipment/progression retained.

build_assets.py also includes the cinematic briefing recipe when rebuilding this package's assets; its tile, sprite and sound processing is unchanged.
