Grunts - These are your basic punk enemies of Halo. They can dish out a little bit of hurt, but if you take out their leader (a Brute, usually), they’re easy. Just don’t waste your good ammo on them.
Brutes - You have to remove their armor before you can bring them down. Stick to head shots to rack up the damage. They’re not too tough, and fairly common.
Jackals - They’ll be behind a shield most times, so aim for the legs or the openings in the sides to bring them down.
Drones - They don’t pop up too often, but they’re airborne and will swarm you. Drop them quickly before you wind up with a whole mess of them on you.
Hunters - These are the big boys. A rocket in the back is the best way to drop them, or a mess of other weapons. Just don’t go at them from the front, always get behind them.
Flood - These little buggers are nothing initially, just a little scurrying creature that’ll deal small amounts of damage. Let them get a hold of a dead body, however, and you’ve got a problem on your hands. Try to stop them before they pull that off.
Scarab - There are only four of these in game (thankfully), and what you need to do is aim for the legs until they collapse. Then, hop up on their back and shoot your way through to the power source to shut them down for good. If you’re in a vehicle or have a good vantage point, you can drop the power source from above without worrying about the legs.
