Check Your Health and Armor
As we just mentioned, Doom’s enemies aren’t gonna play nice. Not only are they ruthless in their methods of trying to kill you but they’ve also got some pretty powerful attacks and weaponry to help them do so. Therefore, it may seem obvious but always keep an eye on your health. It’s easy to lose track of your health and ammo count when you’re blasting the heads off of demons, finding yourself stranded with no means to defend yourself or just plain dead.
If you find yourself coming under a bit of fire, give your health a glance. If you see some armor lying in a slightly difficult place to reach, take the time to go and grab it. You may not think you need it now when your health is on 100, but when you next jump into a crowded battle it may be the difference between life and death.
