PS5
Possessor(s)’s route to Dessa does not include every boss or open every room. Use traversal upgrades to revisit Campus Hill, Fluorescent Park and Skyscraper Remnants. Several detours yield weapons or upgrades that also make fights easier. Use a separate checklist for Endless; the hidden lobsters are not marked as standard collectibles on the map.
Base PS5 list, with Sanzu City backtracking before facing Dessa.
- Required difficulty: No difficulty setting is required by the base list.
- Missable trophies: Backtracking is available before the final confrontation; use that window for cleanup.
- Multiplayer: None: the full list is single-player.
- PlayStation release: 2025-11-11
Mark blocked routes as you explore Sanzu
Use the starting Kitchen Knives to learn fight timings. When a route seems to require a move Luca does not know yet, note the room and continue. After getting Slide Breaker, Dive Breaker and Water Dash, revisit earlier areas; underwater corners and low openings can lead to equipment or encounters.
- Use fast travel for return trips after unlocking new movement.
Finish the arsenal through side pursuits
In Fluorescent Park, follow Find The Hunter to the Sightless All-Star fight for the Baseball Bat. At Campus Hill, find the indoor branch where Dive Breaker launches you towards the Benchwarmer’s room. After Tygo in the Aquarium, use the Executive’s Key on locked doors and follow the route to the Hockey Stick. Verify the resulting weapon in inventory, not just the boss clear.
- Check all four main weapons and pick up special gear along the way.
Return to optional bosses before Dessa
From Campus East, return to the courtyard, open the red-plant shortcut and whip-swing towards Mr Demars. Collect Professor Foss’s microfilms for the Document Eater route. At the Rusted Dockyard, look up after the first waterfall climb for Dr. Michaels’s office. In his fight, jump the sweep and punish the opening instead of chasing each animation.
- Check each optional boss trophy even when the main story lets you continue.
Collect lobsters room by room
The lobsters are red and easy to miss. Walk up and interact with R1; walking past the spot will not collect one. Mark a room only after picking it up. Use the completed community map, as early Endless guides listed only some of them. Start with Skyscraper Remnants and revisit routes gated by traversal moves.
- Tick points off the community map as you reach them on PS5.
Check affixes, health and medication before the Rift
Before fighting Dessa, make a regional sweep and compare inventories. Weapons, Special Gear, Affixes and abilities are separate collections. Prioritise missing health and medication upgrades since they help with the finale. Check the hidden campus rooms and Sanzu Tour Guide’s region coverage before closing out the run.
- Clear your list of remaining rooms and check each collection trophy separately.

Frequently asked questions
Does the story require every boss?
No. Some are detours with their own trophies and rewards. Return to their routes before fighting Dessa.
Do lobsters show up on the in-game map?
Not as standard collectible markers. The completed community map includes specimens that early guides missed.
Why is a previously visited passage still shut?
Some require a move or a specific key. Come back with the relevant upgrade; for example, Dive Breaker opens the route above the branch on campus.
