The indicator will tell you from which direction your enemies will come, so you?d better prepare for the war in advance. You can throw grenades, but remember that your dynamites are not endless. Use them wisely. Sometimes when kill some foes, you will see fire energy ball, go and get it?you will be more powerful after you get it. Pay attention to your health bar. Good luck!
