Starhawk is not only a great game, and incredibly fun. However, if you're just starting out in this wild landscape, you might need some help to get ahead, and keep your own deaths to a minimum.
1. Hawk Vs Dude? Dude wins!
It's not easy fighting a Hawk. They're larger and have greater firepower than you, but they aren't impossible to destroy when it's just human(oid) to Hawk. In fact, with your default loadout (your rifle and 3 grenades), you can destroy a Hawk, provided that it is in bipedal form. Make sure to aim those grenades right at its center. All 3 grenades can turn a Hawk to scrap, but hitting a moving target with them is tough. So if you you run out of grenades, finish the Hawk off with your gun.
