+// Fix: Show score screen after cooperative campaign multiplayer game ends
+// ============================================================================
+// Problem: When GameMode is LAN/Internet and session is connected, the game
+// skips the score screen (sub_5C9720) and calls sub_52FEC0 instead.
+// This causes cooperative campaign multiplayer games to skip the score screen.
+//
+// Solution: Hook the call to sub_52FEC0 and check if the current MP game mode
+// is cooperative (MapFilter == "cooperative"). This supports multiple
+// cooperative mode indices defined in mpmodes.ini.
+// ============================================================================
