All Will Fall is a survival city builder where every wall, floor, and support beam you place is subject to real physics simulation, meaning the structures you raise can also collapse under their own weight if you build carelessly. Developed by All Parts Connected and published by tinyBuild, the game drops you into a post-apocalyptic world where the ocean has swallowed almost everything, and your job is to grow a small settlement into a towering vertical city on whatever ground remains above the waterline.
The construction system is the foundation everything else rests on. Building works in full 3D across all three dimensions, and the physics model accounts for weight distribution, tension, and material strength. Stack too much concrete on a weak base and the whole thing comes down, potentially taking surrounding structures with it. This forces genuine architectural thinking into what could otherwise be routine placement. Every floor you add upward is a structural decision as much as a logistical one. The research tree unlocks dozens of building types that range from practical rain catchers and smelters to more desperate solutions like dynamo hamster wheels for electricity generation and cannibal huts for when food runs critically low. A painting and decorations tool lets you customize the look of your city, whether you're building rusty favelas, concrete towers, dystopian military bases, or tropical resorts.
The colony simulation runs alongside the construction with three distinct factions. Workers, Sailors, and Engineers each bring unique traits. Sailors have access to boats while Engineers can operate cranes, and their needs for housing, water, food, and leisure frequently clash. Managing those competing demands while establishing resource harvesting, production chains, and a functioning economy is where the leadership side of the game lives. You can govern as a kind shepherd or a strong-hand tyrant, and the game frames that choice through random events that force uncomfortable decisions. Newcomers arrive begging for shelter while your people are already starving. Someone offers tons of meat of unknown origin to solve a hunger crisis. The game puts the call in your hands and lets the consequences play out.
Exploration opens up as receding tides uncover new areas and resource nodes beyond your starting position. Reaching them requires machinery, ladders, explosives, and other tools, sending survivors out to scavenge a drowned world for precious materials and building space. The water level itself becomes a variable that reshapes what's available to you over time.
The campaign is split into eight handcrafted scenarios, each with its own narrative setup, atmosphere, goals, map layout, and gameplay conditions. One has you converting an abandoned oil rig into a fortified base. Another puts your city on top of a tanker sailing across the ocean in search of land. A third sets a clock ticking as you prepare for an incoming tornado. The variety demands adaptation, you'll need to rethink city layouts, relocate resources, and adjust strategy to meet each scenario's specific challenges. All Parts Connected estimates the campaign offers over 100 hours of content depending on playstyle. A Custom Scenario mode lets you mix mechanics in unexpected combinations, like adding roguelike progression to a tropical island run by moon-worshipping cultists, which extends the campaign's replayability considerably.
Beyond the campaign, a sandbox mode strips away survival pressure entirely for players who want to focus purely on construction and creativity. An extensive level editor allows you to tweak map layouts, weather conditions, available resources, city foundations, progression difficulty, society growth rate, and the types of random events that appear. Creations can be shared through Steam Workshop, and the game already has an active community building and sharing custom scenarios.
