Your first 3 hours.

The prologue is fixed.

Every run opens at Tenebrous Sea— the shipwreck-deck prologue. You can't skip it; there are no difficulty / NG+ shortcuts that let you pop straight into the Generators. The prologue takes 15-25 minutes depending on how much you explore. It teaches the core dash-and-dig moveset, the basic combat read, and ends with the Nether Kraken — a forgiving boss whose only real punish is the side-bracket tentacle volley. Don't worry about optimization here.

After Nether Kraken falls you arrive at Loner's Landing, meet Lady (the recurring survivor NPC who threads the entire campaign), and the road opens to Ossex— the central hub. The prologue → Ossex transition is one-way. Once you land in Ossex you don't go back to the shipwreck deck.

Where the campaign actually opens up.

Ossex is the central plaza-with-shops hub. It has the highest save shrine density in the game (plaza-centre + safehouse + Radiant Manor approach) and houses the merchants who'll later sell weapon upgrades, sidearm slots, and trinket-economy items. The first 20 minutes in Ossex are exploration — talk to every NPC, check the shop inventory, find the plaza shrine, scout the four Generator-region exit signs. You don't need to commit to a region yet.

Ossex is also where the recurring rivals (the Hulk Trooper fight in the prologue arena to the south, the Maxi encounter to the north, the Thorne setup at Radiant Manor to the east) re-enter the campaign. None of them are mandatory on the first pass — Thorne in particular is the campaign's final-act boss, not a first-3-hours target. Treat the rivals as “come back later” flags for now.

Four any-order Generators unlock simultaneously.

Once you clear Ossex's entry sequence (talk to Lady, rest at the plaza shrine, find the four Generator exit signs) the four any-order Generators all open at once: Queensbury Crypt, Septemburg, Nox's Bayou, and Bone Beach. None of them gates the others. The two progression-gated regions — Coltrane Peak and Astral Orrery — open only after all four any-order regions clear.

For your first 3 hours, you'll only touch one Generator — clearing one all the way through the boss and the Spark Generator activation typically takes 90-150 minutes on a blind run. The decision you actually make right now is which one to start with.

Which any-order region fits your hour 1-3?

The four any-order Generators each lean on a different core mechanic. None is “harder” than the others, but they reward different reads. Pick the one that matches what you actually want from the next 3 hours:

1. Queensbury Crypt — story-first players. The crypt-cellar Generator runs on a tight corridor combat rhythm. The Duchess gate-boss is a clean 2-phase read (overhead-club + bunny adds → flesh-sweep + corruption burst), and the post-fight Duke quest seeds the campaign's primary ending tree. Choose Queensbury Crypt first if you want the moral-choice setup to land while Mina still has the prologue's full HP and a fresh dash budget. The fast-travel beacon you earn at the top of the tower climb makes returning to Ossex frictionless.
2. Septemburg — combat-rhythm players.The autumn-farmland approach into the Tower interior is the campaign's first sustained projectile-lane test. The Madd House mini-encounter (ghost-hand swipes + pumpkin bombs) and the Carving Man gate-boss both reward column reading. Choose Septemburg first if you want to ladder into the “watch the spread, time the dash” rhythm that pays off in every subsequent boss with a projectile attack.
3. Nox's Bayou — mobility-first players. The poison-swamp traversal forces mobility-trinket prioritisation immediately. The toxic puddles punish lazy positioning, and the Nox Beast fight is built around spore-volley dodging. Choose Bayou first if you want a traversal-focused opening — the region has 5 save shrines (the highest density of any Generator) because the puddle mechanic rewards frequent rests.
4. Bone Beach — puzzle / vertical-descent players. The mining-town Generator is the most mechanically distinct of the four — the Bonestone economy beat unlocks here, and the giant-skeleton vertical descent teaches the dig mechanic that the other three Generators only hint at. Major Miner is a forgiving boss (3 attacks, all readable telegraphs). Choose Bone Beach first if you want a strong sense of mechanical novelty in hour 1-3, even at the cost of slightly less combat density.

Our pick for most first-time players: Queensbury Crypt. It teaches the cleanest gate-boss read, the Duke quest hands you a permanent mechanical buff (Proto Spark) you carry the whole campaign, and the tower-climb finish hands you fast-travel earlier than any other Generator.

What 3 hours actually buys you.

On a blind run with average-explorer pacing, three hours covers roughly:

• Hour 1. Tenebrous Sea prologue (15-25 min) → Ossex exploration + shop browse + plaza shrine (20-30 min) → first entry into the chosen Generator (5-15 min).
• Hour 2.Generator midgame — region map cleared to roughly the save-shrine before the gate boss. Sidearm slot might unlock here if you stumble into an Ossex side-room reward. First miniboss (Queensbury's bunny adds, Septemburg's Madd House, Bayou's spore-volley wave, Bone Beach's first vertical descent) falls.
• Hour 3.Gate boss prep — last save shrine rest, trinket loadout swap, and the first 1-2 attempts on the boss. Most blind runs land the gate-boss kill late in hour 3 or early in hour 4. The Spark Generator activation that follows is the campaign's first “the campaign clicked” moment.

A speed-focused player can clear an any-order Generator in 90 minutes; an explorer-focused player can take 4+ hours on the same Generator and not feel slow. Both are fine — the campaign rewards both pacings equally.

Mistakes that torpedo a blind run.

1. Trying to commit to two Generators at once. New players sometimes bounce between Queensbury Crypt and Septemburg on the first 3 hours, thinking they need to “scout” multiple regions. Don't. Pick one and finish it. The any-order rotation means you can leave the other three for later sessions with no penalty; bouncing wastes the save-shrine warm-up time in each region.
2. Skipping the Ossex shop browse. Walking into the first Generator without checking the Ossex merchants means you miss the trinket and sidearm buys that flat-line the first gate boss. Spend the 5 minutes before you commit.
3. Forgetting the dig mechanic.Mina has a dig that the prologue introduces in a single tutorial beat. In the Generators, dig is the only way to reach several collectibles and (in Bone Beach) several traversal segments. Players who don't internalise it early lose hours of progress on second visits.
4. Treating the recurring rivals as fights. Hulk Trooper, Maxi, and the Radiant Manor approach (Thorne) are all visible from Ossex on the first visit. None of them are mandatory first-3-hours targets — Thorne is a final-act boss, Hulk Trooper rewards a sidearm unlock on the second encounter, Maxi is a recurring harasser. Engaging them on hour 1 wastes consumables.
5. Saving every consumable for the boss. New players over-economize on the regional standard enemies, then arrive at the gate boss with maxed consumables and unfamiliar combat reads. Spend consumables on standard enemies to warm up the combat timing; the gate boss rewards a confident dash budget more than it rewards a full potion bag.
6. Not resting at every save shrine. Save shrines do triple duty — full HP regen, weapon / trinket loadout swap, and (once the regional beacon unlocks) fast-travel anchor. Walking past one because “I'm fine” is the single most common cause of first-3-hours run-ending deaths.

The exit signal.

A Generator counts as cleared when its main boss(es) fall and the Spark Generator beacon activates. The cleared-state signals are unmistakable: the boss death cinematic plays, the Spark Generator pillar lights up gold, and the fast- travel beacon (a small standing stone near the region entrance) glows. Once you see all three, walk back to Ossex and bank the progress.

You don't have to finish collectibles in the same session as the boss kill. Save shrines persist through fast-travel exits, so you can come back later with better loadouts or different trinkets to clean up missables. Several collectibles in each Generator are visible on the first pass but only reachable with traversal upgrades unlocked elsewhere — leave them; they'll be there.

Where to look next.

Once your first Generator clears, the next decision is whether to do all four any-order Generators back-to-back or rotate through them with side content between. There's no campaign reason to rush — Coltrane Peak and Astral Orrery only open after all four any-order regions clear. Most blind runs spend 8-15 hours on the any-order rotation before the gates open.
