A playable tactical systems simulation built around one idea: the environment, infrastructure and information are all part of the game state. The first vertical slice models a small world instead of faking a large one.
BREACHLINE is not being treated as another portfolio experiment. The vertical slice is deliberately constrained to one operation that can be played, tested, measured and improved before the product expands.
The objective is to prove the architecture of an interactive world: actors make decisions, geometry changes, facility systems depend on one another, knowledge expires, automated security reacts and an objective resolves from the resulting state.
Surfaces have explicit gameplay state. A route can be intact, reinforced, damaged or opened. Traversability changes because state changes—not because the presentation pretends it did.
The building behaves as connected infrastructure. Power affects cameras. Shutters affect routes. Operators can alter facility state and create a different tactical problem without changing the underlying map file.
Knowledge is represented separately from world state. Observations have a source, confidence and lifetime, allowing information to be useful without becoming permanent omniscience.
Rivet specialises in RIFT state and can reconfigure the reinforced interaction in the vertical slice.
Kite maps nearby facility and security state into temporary Intel Graph observations.
Mote temporarily disrupts automated detection around the operator, changing what the security layer can observe.
Latch can alter shutter state remotely, demonstrating that operator abilities are authored above shared world systems.
The browser build is the immediately playable rules reference. A separate C++ simulation proves core domain behaviour without presentation. The Unreal Engine 5 scaffold is the production-engine direction, but a cooked Unreal build is intentionally not claimed until it has actually been compiled and packaged in an Unreal-capable environment.
The flagship rule is simple: finish this operation before multiplying maps, modes or unrelated game concepts.
