About the Game
All Will Fall is a post-apocalyptic, systems-driven survival city builder/colony sim where every structure can collapse.
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.
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.
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.
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.
All Will Fall features an extensive sandbox toolkit for creating and sharing your own levels with the community via Steam Workshop. If you want to just focus on city-building with no stressful survival challenges, this mode is for you.
Create custom Scenarios using the extensive level editor that allows you to tweak map layouts, weather conditions, available resources, city foundations, and more, unlocking hundreds of hours of gameplay beyond the campaign.
Modify gameplay conditions such as progression difficulty, society growth rate, and types of random events. Make a nail-biting survival experience or a level that’s all about chill vibes and creativity with no pressure at all.
Share your sandbox creations with the world via Steam Workshop. Join the growing, active All Will Fall community on Discord and build survival colony sim adventures together with thousands of players around the globe.

1.4.0 Foundations Update & 25% Off Sale!
Hello Survivors,All Will Fall is currently 25% off and we've got an update to share with you!Foundation ReworkWe are introducing a new Ground system which determines the costs of building Foundations. The deeper you build, the more sand it will cost you. We hope that this will create unique designs and choices on how to shape up your city in the late game. And don’t worry, we're also introducing new buildings to help you with these challenges!Yellow color marks shallows. It seems like something has stood there before...New Support BuildingsFor a long time Foundations were exclusively late game - they cost expensive Sand resources and could be built anywhere. Having them in the early game would have trivialized the need for clever expansions of building cities. But now that the Ground system limits places where they can be built without extra Sand, we are making Wooden and Metal foundations available! These are new alternative ways of bridging gaps between city ruins earlier in the game, giving you a choice to either build hanging bridges or standing onesWooden Foundations are supporting bridges, while Metal ones are holding up the Sand ExtractorNew diagonal and other support block versions!ImprovementsSailable area indication are now inverted to un-sailable area - makes it much easier to see when building by the sea!That bridge looks a bit too low for the boat to pass under!Lots of Building construction placement improvements - several edge-cases were improved so that what you’re placing would be more consistent with where the mouse cursor points. Off-grid buildings are now centered correctly, so Roofs are easily built in any direction. Now holding the key to over-build (default key Ctrl) also works with repositioning - you can quickly fix small mistakes without needing to use the Deconstruct tool!Randomtown scenario will now start with lower sea level which allows early foundation building.Added juicy Event reward notifications - you’ll no longer miss any auto-comp...Read full article on Community Announcements ([tB] Tira)Patch NotesOfficial
