How do you beat the boss on steamworks island?

Answer 1

With the monster on the first level you run into the monster it makes the monster angry and it pushes you back. As soon as you land on the ground start shooting with your gun. Do this 3 times and the monster will die.

The monster on the second floor is a little harder. you do the exact same thing that you did with the first one but avoid the little bomb things. you run at the monster and it throws you back and when you land on the ground you start shooting it. Do this 3 times and the monster will die.

The third monster is the hardest. You have to stand under the bombs until all of them have dropped. while you are doing this try to shoot the bullets that the monster is shooting at you so you don't get thrown back. Then if you look up you will see vines hanging down from where the bombs used to hang, if you stand under the second one and duck, you are close enough to make the monster mad but it can't hit you with its head. when it shoots out its head you shoot it with your gun. Stay away from the bullets. they knock you back.
