About this game
Every floor is a fight. Every gate is a choice.
NULLRUN is a sci-fi roguelite shooter built for one hand and short sessions. Drag to move, stand still to fire. Clear the floor, then walk through one of the gates that open - and the gate you pick builds the next floor.
FOUR KINDS OF FLOOR, ONE RUN
• Square, amber - an open platform. Sometimes three to five times longer than usual, with the fight scattered down its length; sometimes a T or a Y, with whole wings bolted onto the room.
• Triangle, cyan - a maze. Walls block movement, shots and line of sight.
• Pentagon, green - the Void. A ribbon of walkway over nothing, with branches, loops and gaps your bolts fly across but your legs do not.
• Circle, magenta - a reward run, offered only after a boss. Steer between gates that make your build permanently stronger.
STOP TO SHOOT, MOVE TO DODGE
Moving still fires, just slower. Every fight is that one decision, over and over, faster and faster.
TWELVE ENEMY TYPES THAT ASK DIFFERENT QUESTIONS
Drones rush. Mites swarm. Sentries keep their distance. Wasps fly over walls and gaps. Fuses sprint in and detonate. Blobs split in two, then split again. Aegis walkers eat any bolt that hits their shield - flank them or punish the swing. Menders heal everything around them. Warps blink to your side. Turrets and Glaives hold a line with charged beams.
FIVE BOSS TIERS
A boss every ten floors, then every five past floor 30. Warden, Revenant, Colossus, Nullifier, Eclipse — each bigger, differently coloured, with its own sequence of moves and its own minions. Past floor 28, bosses also start turning up loose on ordinary floors.
TWENTY-EIGHT UPGRADE CARDS
Split barrels, rail rounds that pierce, ricochet, bolts that bounce off walls, orbiting blades and embers, escort drones, a stasis field that slows everything near you, vampirism, a second wind that revives you once. Cards are drawn by rarity - grey, blue, purple, red — and the deeper you go, the better the odds.
GEAR THAT LASTS BETWEEN RUNS
Six equipment slots, twelve item bases, seven rarities from Scrap to Legendary. A deep inventory and a Furnace that forges ten items of one tier into one of the next. Chests are paid for in the materials you earn.
FOUR MATERIALS, ONE PER FLOOR TYPE
Alloy from platforms, Circuit from mazes, Flux from the Void, Prism from reward runs. Hangar upgrades need mixes of them, so the gates you choose decide what you can afford.
SEEDED RUNS
Every run has a seed. Share it and send someone the exact same sixty floors.
MADE FOR PHONES
Portrait, one thumb, offline, no account. Pause whenever you need to. Measured at 120 fps on a Samsung S24 Ultra.
NULLRUN is in active development. New enemies, floor types and cards are on the way.
