In a dying world overtaken by the endless ocean, your goal is to grow a small settlement into a sprawling vertical city of your dreams. Master a deep, innovative 3D construction system that uses real-world physics simulation and keep the city thriving as you manage resources, logistics, production chains, societal needs, random events, and world exploration. Complete 8 handcrafted Scenarios with unique challenges, or create custom adventures using a robust level editor, and share your creations with the world.

PHYSICS-BASED CITY BUILDING – Design and build massive, intricate vertical cities using a unique physics-based 3D construction system that requires you to consider real-world construction aspects and allows growing the city in all three dimensions. The city building mechanic in All Will Fall utilizes a realistic physics simulation model, which means every structure can crumble and cause catastrophic damage if weight distribution, tension, and the strength of materials are not taken into account. From rusty favelas and dystopian military bases to concrete towers and tropical resorts – create the megastructure to be proud of, and customize it to your heart’s content with a powerful painting & decorations tool. Progress through the research tree and unlock dozens of building types essential for survival: rain catchers, smelters, radio towers, lighthouses, or even dynamo ‘hamster wheels’ to generate electricity and cannibal huts to quickly solve hunger.
DEEP COLONY SIMULATION & MANAGEMENT – As the colony grows, so do your responsibilities as its leader. Establish steady resource harvesting, logistics & production chains, manage the economy and societal requests. Go down in history as a kind shepherd or strong-hand tyrant – as long as the city prevails. Three factions – Workers, Sailors, and Engineers – have unique traits, like access to boats or cranes. Use their strengths and navigate their often clashing needs for housing, water, food, and leisure, so the city works like a well-oiled machine. Send the survivors to scavenge the long-lost world, overtaken by the ocean, for precious resources and building space. Receding tides uncover new areas and resource nodes, reachable with machinery, ladders, explosives, and other means. Random events can force you to make difficult yet necessary decisions. Will you accept newcomers begging for shelter when your people are starving? Will you solve this hunger by suddenly giving out tons of meat of unknown origin? Your call.
MULTIPLE SCENARIOS WITH UNIQUE CHALLENGES – Become a true survivalist by completing the campaign, split into 8 Scenarios, offering up to 100+ hours of content depending on playstyle. Each Scenario presents a distinct underlying narrative, atmosphere, goals, challenges, map layout, and gameplay conditions. Turn an abandoned oil rig into a fortified base. Build on top of a tanker and sail across the ocean in search of land. Or race against the clock to prepare the city for the incoming tornado. You will need to adapt to a slew of challenges presented by each Scenario. Don’t hesitate to change the city layout, relocate resources, and tweak your strategy to succeed. Want to add roguelike progression into your tropical island run by Moon-worshipping cultists? Mix multiple gameplay mechanics in surprising ways using the Custom Scenario mode, which drastically increases the campaign’s replayability.
