ALL WILL FALL

All Parts Connected developed and tinyBuild published ALL WILL FALL. The world is gone, swallowed by an endless rising ocean. Your colony survives on a small patch of solid ground surrounded by water, with nowhere to expand horizontally. The only direction left is up. Every structure you build is subject to real physics simulation, meaning a poorly planned floor or an overloaded support beam can bring down entire districts in seconds.

About the Game

The game combines vertical construction physics with deep colony management across three factions: Workers, Sailors, and Engineers. Each faction brings unique capabilities including boat access, crane operation, and construction bonuses, but their needs and demands actively conflict with each other. Keeping all three satisfied simultaneously is the central tension of every session. Furthermore, water levels change dynamically as the game progresses, submerging lower districts and uncovering new explorable terrain that pushes the city footprint upward over time. Random events including storms, equipment failures, and political crises force reactive decisions that can derail a well-running city if left unmanaged.

Key Features

Real-Time Physics Collapse System: Every structure in the city is subject to full physics simulation covering weight distribution, tension, and material strength. Overloading a support beam or removing a load-bearing wall mid-game triggers real cascading collapses rather than a simple game-over screen. Rebuilding from partial collapses while keeping the surviving population fed and housed is one of the most demanding recovery challenges in the genre.
Three-Faction Colony Management: Workers, Sailors, and Engineers each carry distinct housing requirements, food preferences, and leisure demands. Their needs frequently clash, and satisfying one faction often creates friction with another. Managing faction happiness scores affects your access to specific construction abilities and production bonuses throughout each run.
Changing Water Levels and Exploration: As ocean levels shift, previously submerged areas rise to become new buildable land, while low-lying districts face flooding risk. Sending Sailor faction boats to explore newly surfaced terrain reveals rare resources and structural salvage that accelerate mid-game construction significantly.
8 Handcrafted Scenarios plus Full Sandbox and Level Editor: The scenario mode covers eight distinct challenge configurations with unique starting conditions, map layouts, and win parameters. Beyond that, the full sandbox mode removes survival pressure entirely for players focused on construction, and the built-in level editor lets players design and share custom maps through Steam Workshop.

Similar Game	Key Difference	Best For
Frostpunk 2	Operates as a top-down city survival game on frozen ground with no physics collapse system and a much heavier emphasis on political law-making and large-scale population management across districts.	Players who want a city survival game driven by political pressure and large population numbers rather than structural engineering and vertical construction.
Against the Storm	Runs as a roguelite city builder in a forest setting with fixed 2D layouts and no physics simulation. Its loop focuses on resource efficiency across short sessions rather than long-form vertical city growth.	Players who want a faster, more repeatable city builder with roguelite variety rather than a single long-form colony campaign.
Raft	Shares the ocean survival premise but focuses on first-person survival crafting on a small floating platform rather than top-down city management with faction politics and physics-based structural engineering.	Players who want a hands-on ocean survival experience in first person rather than a management-layer city builder.

System Requirements

Because the game runs full real-time physics across an entire vertical city, it is more demanding than most city builders at its price point. An SSD is recommended at both tiers. Below are the full PC specs.
