Using one game project as a long-term laboratory for interconnected systems

Large interactive products become difficult when individually capable systems have to behave as one coherent whole.

Fate of the Few has been Marc Thornton’s long-running environment for exploring that problem inside Unreal Engine. The work combines product direction, systems design, world-building, prototyping, testing and specialist collaboration rather than treating the project as a collection of isolated features.

A significant part of the R&D has focused on AI behaviour and navigation: behaviour trees and blackboards, sight-and-sound perception, target selection, pathfinding, decision logic and crowd-aware navigation.

The wider framework brings together advanced locomotion, vaulting, parkour, climbing, swimming, inventory, interaction, weapons and vehicle physics. Procedural tools have also been used to accelerate experimentation with environments and playable spaces.

Marc has led the overall product direction and managed specialist development of complex reusable frameworks, while also carrying out substantial hands-on Unreal Engine R&D himself. The distinction matters: specialist contributors receive the technical credit for the implementation they own, while Marc’s role is to keep the systems, product requirements and wider experience coherent.

The project includes a supporting technical demonstration and remains in independent development alongside Marc’s wider product and professional work.

For Digital SHIFT, Fate of the Few is valuable because it continuously tests the kind of systems thinking that transfers well beyond games: integrating third-party technology, diagnosing interactions between complex components, deciding what should be standardised or customised, and coordinating specialist work without losing sight of the product people are ultimately meant to use.
