RIFTBLADE

PHOTOSENSITIVITY WARNING

This game contains flashing lights, rapid screen flashes, high-contrast strobing and fast-moving patterns. A very small number of people may experience seizures when exposed to these, even with no previous history of seizures or epilepsy.

Stop playing immediately and consult a doctor if you experience dizziness, altered vision, eye or muscle twitching, disorientation, involuntary movement, or loss of awareness.

If you are unsure, turn on REDUCED FLASHES below. It removes the impact frames and the chip pulse, and damps screen flashes, camera shake, bursts and speed lines. Nothing in the game becomes harder to play.

PLAY WELL

Sit back from the screen in a well-lit room. Take a 10-minute break every hour. Stop if your eyes, hands or wrists start to ache — this game asks for a lot of quick taps. Sleep beats one more attempt at the Sovereign; it will still be there, and it will remember you.

RIFTBLADE

open plane · seven weapons · three wardens that remember you

Depth was taken from the world on purpose. The Concord called it the Flatten. You carry the last blade that remembers volume — where you stand, the world can be thick again. Three Wardens enforce the plane. They train between rounds, and they read you.

THE OPEN PLANE

Getting thereBEGIN or CONTINUE drops you in the Sanctuary — the safe hub at the centre of the map Interactwalk up to anything glowing; a prompt appears — tap or click it, or slash Citadelsthe three Wardens: Emberjaw (north-west), Glacier Warden (north-east), the Sovereign (north) Weapon shrinesred squares on the map — beat the sentries guarding one to claim its weapon Rift Shards ◆from sentries and gold crystals — spend them at the Smith's forge to buy and temper weapons Waystonesheal HP & MP and fast-travel to the next waystone Top barARMORY · SANCTUARY (warp home, full heal) · DOJO (direct duels, mask wall)

The Concord collapsed everything to a single plane, so the thing that hunts through depth could never reach us again. It worked. Nine hundred years of safe, thin, obedient life. You will fight each Warden three times. They do not wait between rounds — they carry what they learn into the next encounter.

THE RULE. Height and depth do the same amount of work, never the same work.
2D — jump, aerial slashes (×1.25), dive-slam (DASH in the air), juggle a launched Warden, and reach the ward's high facet. Combo scales to ×2.44.
3D — no jump, but flat ×1.35, orbit to the rotating facet, and bait charges into walls.
SHIFT only clears threats within 7 units of you and invites an immediate counter-attack. It is a panic button, not a reset.
