Completion criteria

• Repeatedly swing at nearby enemies when in range.
• Avoid swinging at allies unless they personally attack the user.
• If all enemies are cleared out, look for nearby structures before searching for the next enemy. Use melee attacks to break them if there are any.
• Switch modes to maximize damage.
