Bold Hole

Early Access development: this game is unfinished

The game is still in active development. Content, balance and performance will continue to change. We plan to launch at Steam's minimum base-price tier (US$0.99 in the US, with the corresponding minimum tier in other regions) and gradually increase the price as content improves. Please decide based on the content currently offered.

Start with a pebble. Make the whole planet your next bite.

Swallow towers, traffic and the people on the rooftops

Guide a growing black hole across a tiny 3D planet. Start with rocks and streetlights, then move on to cars, skyscrapers and defense headquarters. Buildings topple, collide and sink into the well while people tumble from rooftops or open parachutes and glide away. Bigger meals bring stronger resistance.

Turn your pursuers into food

Helicopters and tanks keep firing as you move. Knock aircraft down with a shockwave, pull nearby people, vehicles and buildings into your well with a gravity surge, or freeze them in a time-stasis field. Bullets fired from outside the field stop as they enter. Read the nuclear warning and dash away while the expanding blast throws objects behind you into the air.

Hunt the president. Disrupt the city

The president appears with bodyguards and decoys, then tries to escape by limousine, helicopter or rocket. Find the real target and intercept the convoy. Swallow a dam to reveal fish and submerged cars, or knock out power stations to plunge a town into darkness. Your appetite can trigger panic and evacuations.

Build a different black hole each run

Choose one of three upgrades as you level up. Combine dash and shock variants with gravity, swallowing combos, fission, evolutions and mutations. Spend earned dark matter in the Singularity Workshop on permanent growth, ability variants and starting cores. Powerful cores have unlock challenges; a new save starts without one.

From Earth to the Iron Fortress

The base game includes two chapters, an enemy-free Free Mode, two selectable black-hole styles (the two on the left; the right-hand styles are not available yet), Photo Mode and an adjustable miniature-cartoon look. Play with keyboard and mouse in English or Simplified Chinese.

Free demo scope

Play the first part of Earth up to level 16, followed by an ending preview. The demo includes the fiery accretion-disk style; the base game additionally offers the leftmost style, Free Mode and the Singularity Workshop; the two right-hand styles are not available yet. Demo and full-game saves are separate.

The base game is planned for Early Access. See the Early Access section for the current scope and future direction.

The trailer includes development-only appearances. The two right-hand styles are not available in the current release.
