26 — Sea Polluter

One of the hardest sub-chapters yet, with three debuts: Capy's crits, Brollow's rushes, and Berserkory's Lv.12 waves. ItF Chapter 2's Aliens also arrive.

A gauntlet of introductions. Capy debuts on Oil Platform — a single-target Red with long range, very high stats, and a Critical chance that ignores your tanks' bulk. Brollow debuts in bulk on I'm Onto You — fragile but faster than every cat in the game, a front-line shredder if not answered immediately. Berserkory closes the set on Revolving-door Floats: a Red Kory with far more health and attack whose every swing produces a Lv.12 Wave Attack, traded for less range, less speed, and a single knockback. Into the Future Chapter 2's Aliens also make their Stories of Legend entrance, so Ancient Trial assumes your Crystal treasures are done.

Beyond the debuts, the wiki flags Littering Coast, Benzene Field, and Government Watchdog as carelessness-punishers, and Sweat and Aldehyde as RNG-heavy — budget extra attempts.
