+# Task bf-z9m: Award Score for Combat Kills
+
+## Status: ALREADY COMPLETED
+
+This task was already completed in commit `c1acd83` (2026-06-16 23:40:23).
+
+## Implementation Details
+
+The commit `c1acd83 feat(combat): award score for combat kills` added:
+
+1. **Config Field**: `KillScore int` in `engine/types.go:182` with default value of 1 point per kill
+2. **Score Award**: In `engine/turn.go:272-275`, score is incremented immediately after tracking `CombatDeaths`
+
+```go
+// Track combat deaths for the killer's player
+if e.Owner < len(gs.CombatDeaths) {
+    gs.CombatDeaths[e.Owner]++
+}
+// Award score for the kill
+if e.Owner < len(gs.Players) {
+    gs.Players[e.Owner].Score += gs.Config.KillScore
+}
+```
+
+## Verification
+
+- Kill score is configurable via `Config.KillScore`
+- Default value is 1 point per kill (matches request)
+- Score is awarded to the killer's player in the combat loop
+- Implementation matches the bead requirements exactly
+
+## Notes
+
+No code changes were required for this bead - the feature was already implemented.
