<syntaxhighlight lang="text">HOTFIX / updateWeaponHUD is not defined

Do NOT change gameplay, map, enemies, or rendering.
Only fix the initialization crash.

1) Ensure a function named updateWeaponHUD exists.
* If you already have a function that updates weapon UI, alias it:
  window.updateWeaponHUD = existingFunctionName;

2) If no weapon HUD update function exists, implement a minimal one:
* It should update the 3 weapon cards (RIFLE / SHOTGUN / MISSILE) active state
* It should update bottom-right weapon label text (e.g. "SHOTGUN ACTIVE")
* It should be safe to call even if UI elements are missing:
* use null checks and return gracefully

3) Replace direct calls with safe-call:
* Instead of updateWeaponHUD(), do:
  if (typeof updateWeaponHUD === "function") updateWeaponHUD();

Acceptance:
* Game boots without “INIT FAILED”.
* Weapon switching Q/E still updates HUD correctly.
