Elroy took the K590NM into his own chest — the merge that started the war.
GRIDFALL is built for portrait. Turn your phone upright and step back into the Merge.
The goal. Break the Syndicate core (30 HP) before Nexus breaks yours. Fighters must fall before a core can be hit.
Your turn. Energy refills and grows each round. Play fighters and drones, fire techniques, then attack — tap your fighter, then tap its target.
Power graphics. Every technique erupts in its fighter's energy color — gold shockwaves, ice shatter, crimson arcs. Watch the holograms: they fight above the cards.
Brotherhood. Field any two brothers for Brothers in Arms (+2 power, techniques cost 1 less). Field all three to arm FAMILY BUSINESS — one massive combined strike.
Relics. Crystals charge one pip per turn. At full charge, unleash the Ultimate: ANCHOR'S SUN (yours) or ICE AGE (his).
The coach. Aria runs overwatch from the brownstone. She walks you through your first moves, then calls the fight live.
Mulligan & fatigue. Every match deals a fresh random five — one free mulligan before turn one. And if your deck runs dry, each empty draw burns your core for escalating fatigue damage. Stalling is a losing plan.
Keys & previews. Play by keyboard: number keys fire hand cards, E ends the turn. Hover or focus a glowing target before you commit — the arena shows the exact damage, and flags a lethal hit.
Five banks, forty pads — every sound synthesized live, run through the arena's reverb & echo sends. Per-pad volume, mute, solo and loop; ultimates choke each other. Drag the XY pad to bend the space.
X drives the reverb send, Y drives the delay feedback. Every pad and the music run through both.
The 68-card Sentiens set — the fighters, swarm and signature tactics in every deck. Tap BATTLE below to take them into the Merge.

















Your record, your sound, your arena — all kept on this device.
