Chapter 3 Walkthrough — Boat & Xenobus Boss
Chapter 3 is the finale of Weird Strict Dad's main story. After the Chapter 2 laboratory outcome, survivors flee to a dock and board a small boat meant to reach open water beyond Xenobus's influence. The map compresses into tight deck corridors, cargo holds, and a final boss arena where Xenobus attacks directly. Oxygen management returns with a portable tank system separate from the house generator. Jerry may appear in possessed form during transit. This walkthrough covers route navigation, supply priorities, and each Xenobus boss phase so your squad clears the campaign.
Boarding the Boat
Stock noodles and water before the dock transition — boat galley prices are high and vending interactables break during boss phases. Assign packs: one oxygen tracker, one repair kit holder for deck leaks, one combat flex for boss adds.
Initial deck segment teaches boat movement — slower strafe, swaying camera, and rail hazards that knock players overboard for instant down states unless grabbed with E by teammates.
Oxygen on the Boat
Portable oxygen tanks spawn in engine room and cargo nets. Unlike Chapter 1 generator logic, O2 here drains constantly in enclosed lower decks. Surface vents on upper deck pause drain briefly — callouts help teammates refuel tanks at engine interact points.
If O2 hits zero, characters choke with reduced vision until tank swap or wipe. Nightmare Mode doubles drain rate below deck.
Xenobus Boss Fight
Phase one: Xenobus slams the hull from outside — dodge telegraphed impact zones marked by red deck decals. Repair prompts appear on rail breaches; ignore them too long and the boat floods for wipe.
Phase two: Tentacles board the deck. Shoot or interact with glowing weak points at tentacle bases while kiting Jerry apparitions that chase noise. Sprint sparingly — deck sway reduces energy regen.
Phase three: Xenobus manifests on deck in humanoid form. Cycle damage windows when its core glows after tentacle slams. Administer leftover antidote interactable if carried from Chapter 2 for bonus damage in true ending runs. Victory triggers escape raft cinematic and leads into Chapter 4 airport arc.
After Beating Chapter 3
Chapter 3 completion unlocks Chapter 4 in story select and awards the Survived Chapter 3 badge. Mom's rescue is temporary — Xenobus re-abducts Jerry and sends the family to the airport. Redeem 300KMEMBERS for Gold Glass if still active before continuing Book I finale.
Frequently Asked Questions
Can you fall off the boat?
Yes. Overboard usually means death unless a teammate grabs you at the rail within seconds. Crouch near edges during sway animations.
Is Jerry on the boat?
Possessed Jerry apparitions appear in phase two as add enemies. They use simplified AI but still punish isolated players.
How many Xenobus phases are there?
Three main phases: hull assault, tentacle boarding, and core manifestation. Cutscene transitions separate them with brief supply refill windows.
Does Chapter 2 ending affect the boss?
True ending with antidote carried grants optional interact damage in phase three. Other endings change dialogue but boss mechanics stay similar in Season 1.
What rewards drop after completion?
Campaign badges, coin bonuses, chapter select freedom, and access to post-game modes like Infinite and Frenzy depending on lobby version.
