SONIC FRONTIERS 100% guide

The achievement unlocks when you finish any Cyber Space stage under its S-rank time. Return to the 1-1 portal near the start of Kronos and run it focusing only on speed: boost through, skip rings, and ignore the red star rings. Avoid 1-2, which has the reputation of being the hardest S rank in the game.

The achievement unlocks when all four missions are complete in a single Cyber Space stage. Keep using 1-1. After your S-rank run, do a slow run for the red star rings and the ring target, since time no longer matters. Any one stage is enough. You do not need all missions everywhere.

Story achievement. It unlocks once the Kronos tutorials are done, around the time you get your first Chaos Emerald.

Story-related. It unlocks when you beat the Ninja guardian during the tutorials. Pick up the Portal Gear it drops. This is also your first entry toward Threats Identified.

Destroy 100 breakable objects. Crates, rocks, and objects in Cyber Space all count, and this comes naturally within the first hours.

A Power Boost activates when you hold the maximum number of rings. A short power-up effect plays, and boosting from that state is a Power Boost. The cap starts at 400 rings and rises with Ring level, so grab this before you spend any Koco on Ring level. Cyloop a ring-rich area or chain ring lines until you hit the cap, then boost.

Heading toward the Red Chaos Emerald vault, you reach ruins south of it with an Elder Koco. Talk to him to unlock this. Elder Koco raises Speed and Ring level in exchange for Koco.

Forced. It unlocks when you talk to Hermit Koco after the Red Emerald scene. He takes Red Seeds of Power and Blue Seeds of Defense, and he can trade Ring levels for Speed levels and back.

Buy Phantom Rush from the skill tree. It is the second skill and costs 3 skill points. Fill the combo meter by attacking without the combo breaking. When the meter turns purple, Phantom Rush is active. Keep attacking so the Phantom Rush attack actually lands, and the achievement unlocks. It must be done in the open world, not in the training simulator.

Activate Phantom Rush 50 times outside the training simulator. On Xbox this shows no progress until it unlocks, so count it yourself and don't assume it is broken.

Farm it on the Asura guardian on Kronos. Attack its legs, which never interrupt your combo. Let the meter drain completely, then refill it, and repeat until the achievement unlocks. Avoid killing the Asura during the farm. Defeat it afterward for Threats Identified.

Collect 200 Koco. The count is cumulative, so spending them at Elder Koco doesn't reset it. Free the Koco groups you pass and this unlocks during normal play on Kronos or Ares.

Big's fishing portal (a purple portal with a fish icon on the map) is on the western peninsula of Kronos. It needs no Portal Gears and appears on the map once Challenges reveal that area. Enter and finish the fishing tutorial by landing a catch.

The achievement unlocks when one fishing spot reaches 100% catches. The completion percentage shows at the portal entrance. Kronos is the cheapest spot at 1 Purple Coin per cast. Its catch list has roughly 30 to 32 entries, including fish, junk, treasure boxes, and the two Koco scrolls. Catches cycle without repeating until the list is complete, so expect around 32 casts.

Purple Coins are found around the island, but a Starfall is the fast source. If you are short, keep exploring and return after the first Starfall.

The scrolls you fish up unlock fast travel to Elder and Hermit Koco. The tokens you earn here are worth saving for Memory Tokens.

Starfalls happen periodically at night, sometimes several in-game days apart, and can't be forced. The first can happen on Kronos. A cutscene plays and the achievement unlocks immediately. If it hasn't happened by the end of Kronos, it will come naturally on a later island.

Earn 100 Purple Coins. During a Starfall, collect the falling star fragments. Each fragment is a slot-machine spin, and three matching symbols pay out a large number of coins. One Starfall usually covers this on its own.

The achievement unlocks when every Challenge on Kronos is done and the map is fully revealed. Challenges are the numbered ? puzzles. Each one reveals part of the map, which in turn shows the next ones. Kronos has about 25, all available without story gating. Some are night-only and show a moon icon. Wait for night or come back after dark.

Repair all seven Cyber Space portals on Kronos with Portal Gears. They need seven gears in total, and 1-1 and 1-7 are free. Portal 1-7 is out of reach at first. Activate the glowing pillars and switches near it to spawn a chain of Grind Rails, then ride the rails up to the portal. Gears drop from guardians, chests, enemies, and Cyloop digging. Repairing is the requirement. Clearing a stage is not.

Safest route: also activate Big's fishing portal on the western peninsula, since it isn't confirmed whether fishing portals count. If it asks for a Portal Gear, spend one. Then play every Kronos stage at least once for Easy Prey. Nine of the ten Cyber Space enemy types are here: Motobug in 1-1, Eggrobo in 1-2, Spiny in 1-3, Buzzer, Chopper, Crabmeat, and Buzz Bomber in 1-6, and the G.U.N. helicopter and tank in 1-7.

The achievement unlocks when all Side Stories on Kronos are viewed. On Kronos these are Amy's optional Memory Token conversations plus Sage's conversations. Use the map icons and filters to find them. Memory Tokens (hearts on Kronos) come from platforming routes, chests, and fishing (5 fishing tokens each), and they don't carry over to the next island, so spend them all here.

Kronos has four guardian types: Ninja, Tower, Asura, and Squid. Guardians show as crossed red swords on the map. A blue star above a guardian's health bar means that individual guardian is already defeated. Kronos has two Squids, but one kill covers the type. The Tower guardian is also needed to reach the Silver Emerald and gives a gear for portal 1-2.

Story achievement. It unlocks when you defeat Giganto. The game moves you straight to Ares Island.

Finish all of Ares's Challenges (about 29). M-044 is night-only. If any ? Challenge stays locked, advance the story and return before Wyvern.

Repair all seven Ares stage portals. They need eight gears in total. Safest route: activate the fishing portal in the far northeast too, and spend a gear on it if asked. Play every Ares stage once for Easy Prey.

View all of Knuckles's optional Memory Token conversations and Sage's Ares conversations. Use the map filter to confirm nothing is left.

Ares has four guardian types: Shark (the southernmost, half-buried in sand at first), Strider, Sumo (on a separate island north of 2-7), and Tank (north of 2-6).

Story achievement. It unlocks when you defeat Wyvern. Climb the tower, ride its lightning trails, and then finish the Super Sonic fight. The game moves you to Chaos Island.

Finish all of Chaos's Challenges (about 24). M-070 through M-072 sit beyond the drawbridge, which only opens through story progress, so finish them once it's down. M-071 is also night-only.

Repair all seven Chaos stage portals. They need seven gears in total. Safest route: activate the fishing portal on the southeast island too, and spend a gear on it if asked. Play every stage once. 3-7 contains the Grabber enemy, which counts for Easy Prey.

View all of Tails's optional Memory Token conversations and Sage's Chaos conversations. A later Sage conversation only appears after the pinball and volcano story sequence, so recheck the Sage filter after that before leaving for Knight.

Chaos has four new guardian types: Spider (bottom-right of the main island), Shinobi (south of 3-1), Fortress (near 3-7), and Excavator (left of 3-4). It also has another Squid on the 3-5 island. Squid is the same type you beat on Kronos, but this one is often named when Threats Identified doesn't unlock, so defeat it too as a precaution.

Story achievement. It unlocks when you defeat Knight. The story then moves to Rhea Island.

Finish all of Ouranos's Challenges (about 27). M-086 and M-098 are night-only.

Repair all nine Ouranos stage portals. They need 11 gears in total. Portals 4-4 and 4-5 are unreachable until Sage's quest chain extends the bridge.

Portal 4-7 is behind a locked door. Open it by Cyloop-ing the wind chimes in the order centre, left, right, then repair the portal in person. Fast travel to 4-7 can skip the door, and skipping it is reported to block this achievement.

Safest route: activate both Ouranos fishing portals (southwest and southeast) as well, spending a gear if either asks. Play every Ouranos stage once.

View all of Sage's Ouranos conversations with the Sage map filter. "The Telepathic Map" stays locked until you finish Part 2 of the hacking minigame. The rest only need Memory Tokens. Some cost large amounts of Ouranos Memory Tokens. Fishing here is the quickest way to cover them.

The achievement unlocks when every Side Story on all four story islands is viewed. It should unlock with Ouranos Island Expert if the other three islands are done.

Ouranos has six guardian types:

• Red Pillar, near the start
• Caterpillar, on a hill east of 4-2
• Kunoichi, near a fishing spot
• Ghost, north of 4-2, which only appears after you interact with a purple statue
• Silver Hammer, west of 4-3
• Master Ninja, the southernmost guardian on the island to the northeast

That makes 18 distinct guardian types across the game: Kronos 4, Ares 4, Chaos 4, and Ouranos 6, plus the precautionary Chaos Squid. The achievement unlocks when the last new type is defeated.

The achievement unlocks when you have defeated every regular enemy type at least once. The commonly cited total is 22 types: 12 in the open world and 10 in Cyber Space. Sources disagree on whether the Cyber Space enemies are strictly required, so treat this as the safest inclusive checklist. Guardians don't count, variants of one type count once, and the game has no tracker:

• Kronos: Soldier, Bubble, Banger, Shell, Cyclone.
• Ares: Hopper, Jellyfish, Sniper, Capture (also on Chaos and Ouranos).
• Chaos: Eagle, the large bird that roams Chaos Island (it can also be ridden to reach small islands).
• Rhea / Ouranos: Balloon, inside Rhea's third, fourth, and fifth towers and also on Ouranos.
• Ouranos: Wolf pack near portal 4-1.
• Cyber Space: Motobug (1-1), Eggrobo (1-2), Spiny (1-3), Buzzer, Chopper, Crabmeat, and Buzz Bomber (1-6), G.U.N. helicopter and tank (1-7), Grabber (3-7).

Finishing a stage isn't enough: deliberately defeat at least one of each listed Cyber Space enemy. It isn't confirmed whether Chopper and the G.U.N. helicopter and tank are actually required, so defeat them in 1-6 and 1-7 anyway. The Wolf pack is usually the last one, so expect the achievement here at the latest. If it doesn't unlock, the usual culprits are Capture, Eagle, Balloon, or a skipped Kronos stage.

Raise Power to level 99 by giving Red Seeds of Power to Hermit Koco.

Raise Defense to level 99 by giving Blue Seeds of Defense to Hermit Koco.

Raise Ring level to 99 by giving Koco to Elder Koco. Elder Koco supports bulk upgrades, so you don't have to sit through one animation per level.

Raise Speed to level 99 at Elder Koco. Hermit Koco's Ring-to-Speed swap is useful if one stat is close to maxed and the other isn't. Plan on buying Koco in large batches. Expect a few thousand Koco across Speed and Ring, minus whatever you've already spent.

The achievement unlocks when the whole skill tree is bought. It needs 224 skill points total. Most players have nearly enough from normal play by now. Skill Pieces fill the skill-point gauge, and each full gauge gives one skill point. Top up with 50-piece Skill Piece bundles from Big, or with Cyloop dig circles and air tricks off a stationary spring.

Story achievement. It unlocks when you defeat Supreme, the Ouranos Titan.

Story achievement. It unlocks when you defeat the final threat and finish the main story, on any difficulty.
