bw-combat-matrix

Equal-cost counter matrix for every Brood War unit pair: exact per-hit duels scored by Lanchester’s square law.

Overview

Every number comes from the game’s own .dat files, cross-checked against BWAPI. Combat rules are converted from OpenBW’s engine source rather than wiki tables. The two values the engine can’t fix (Firebat hits and Interceptor cycle) are empirical, labelled as such, and adjustable. The repo README holds the pipeline and the model limits.

Status (2026-10-18)

• .dat decoder + BWAPI cross-check (2,344 fields; only turret-hull diffs)
• Duel engine with shields/armor/type order, stim, adrenal, regen, acid spores, carrier, reaver, suicide, mines; hits-to-kill both ways (volley + in-fight); 23 hand-worked tests
• Interactive page: per-side upgrades, resources (gas weight) or supply cost
• Local commit (54a7f2a)
• GitHub remote
• Splash / army-scale focus-fire (the model’s biggest blind spot: Firebat vs Zergling reads 0.29)
