Gatekeeper casts you as a new Guardian, tasked with reclaiming the lost Heart of Time from the encroaching forces of Chaos. Forged by the Creators, your mission spans looping planets, corrupted warrens, and events designed by warped deities. From the crystalline fields of Aridune to the shattered sanctums of the Throne Room, you must adapt, learn, and push beyond every failed loop to master the game’s ever‑shifting systems.
The emotional pull lies in each failed run: not defeat, but a scarred step toward mastery. Keeper cores collapse, chants echo in broken halls, and every sprint through Cursed Crossing is a heartbeat away from discovery—or demise.

Starter Gatekeeper & Difficulty

The 1.0 update has rebalanced difficulty choices—there’s no more 80 % tier, and 100 % difficulty is now accessible even for beginners. A balanced start point, it offers enough challenge without overwhelming repetition.
You begin with Hybrid and Nidium unlocked. According to recent meta analysis, Hybrid is the “jack‑of‑all‑trades” packed with a one‑time self‑revive and a post‑revive +50 % DPS boost, making him ideal for your first runs. Nidium’s melee risk is better left until you’ve unlocked his advanced mechanics.
Short roadmap for progression:
- Play Hybrid at 100 % difficulty to complete the first Siren boss.
- Choose to continue the run (don’t reset at Heart of Time). This unlocks Tech Hunter after you return to the Aurora world.
- Later, accumulate 60 total locations cleared to unlock Mediator passively.
Learn Early Loop Systems

Each run follows a pattern: Odyssey → Obelisk → Forge → Conflict / Reception
Green symbols like Chaos Wards, Cells of the Ancients, and the new Instability Generator spawn tailored events. You must navigate them while gathering Monolith Keys—three of them grant access to the Throne Room where you can battle Chaos and fulfill your mission.
Artifacts are your bread and butter. Collect them at Obelisks, or forge multiple into Triads, which vastly amplify passive bonuses. Smart life hacks from the dev team include using Fractals as a one‑time shield and then smelting them into 10 scrap to use later on a Triad of Fractal–crafted build. By mid‑game, artisans like Merchant’s Codex or Manifold Key can turn good items into great ones.
Hybrid’s Path

As a beginner, your job is survival and consistent progress—things Hybrid delivers with ease:
- Self‑Revive gives you a safety net while learning boss patterns.
- His three core abilities cover most encounter types—an evasion, an AOE launcher, and a positioning sphere.
- His scaling is built around damage + mobility + speed, perfect for looping once daily.
In the words of the Tier List guide:
“Hybrid is Mr. Reliable … high reliability & safety.”
If your first run ends before the third location—or you miss a Monolith Key—don’t sweat it. Each attempt teaches something new about timing, artifact use, and your pacing. Because once the world collapses and you loop again, you carry all gained metrics forward.
Community Voices
The subreddits are brimming with moments of triumph—and cautionary tales:
“I made it to stage 17 in singleplayer … on my fourth trip to Celestium, then got stuck in a loading screen with ‘lost connection to host.’”
This leads to two clear beginner rules:
• Before triggering a 3+ hour deep run, manually save and verify your connection if playing solo.
• Between loops, close then relaunch the lobby to avoid duplication or crash bugs.
Still, the overwhelming sentiment:
“This game deserves way more attention … I’m having so much fun. Co‑op? Amazing.”
That mix of romance and community debut is what turns you into a returning seeker.
Mid‑Run Strategies

As your loops grow, these practices distinguish struggling from soaring novices:
‑ Ban unhelpful artifacts early (Ban slots grow to 10 after unlocking them, cutting later build garbage).
‑ Prioritize Prism gains in Emporium—especially early on Quiet Bay’s Merchant’s Altar, which lets you convert Omni‑Stones into late‑game boosts.
‑ Check chaos events’ new extras: Tornado Grasp spawns shifting whirlwinds, and Hailfire Disk deploys bouncing discs—both potential runbreakers without adaptation.
By mid‑game, hyper‑scaling happens through Triad of Status (status spread), Triad of Severance (push+damage), or Triad of Bloodshed (bleed stackers)—grab them when you can mutate under predictable circumstances.
Character Unlock Roads




Once Hybrid feels safe, it’s time to expand your roster. Here’s how your circle grows:
- With 60 total locations cleared across runs, you earn Mediator. No manual requirements—just persistence.
- Visit Aurora twice in a single run by continuing past Chaos to unlock Tech Hunter.
- Use one mediocre Siren fight to unlock Pandora (by entering Apothesis gate) if you want burst magic.
- Secure Aegis by beating Chaos and interacting with the Heart of Time—once you have him, builds break. As the meta says, “S‑Tier … completely broken … battles field scale.”
in Gatekeeper You start as a fledgling behind shattered walls, bow in hand, ciphers in mind. Hybrid gives you breathing room; artifacts whisper promise; each siren killed is another heartbeat gone. You’ll fall. You’ll loop. But when you finally place your hand on the Heart of Time, when the portal closes behind you and the Creators offer new power—you’ll feel that trembling moment of becoming.
