Alright if you are having trouble with any of the bosses in DK:ZH just read this. Boss #1:Boss Hog If you have the BMF Thunderstrike in your arsenal use it.You can obtain it by destroying the barrols in the base and by swimming to it in the wetworld or waterworld(i can't remember it's name but it is the secret level after Nukelear Winter)save the ammo for this boss.If all of your hit's are a success you can kill him in three or four blows then you are sent into the past. Boss #2:Cyborg Scorpion Use your SMG's to blow away it's lethal missile shooting arms.Then all you have to is run into the center platform(if you haven't already)and collect the Gattling Gun and start shooting to high heaven.After it is dead you will be sent to another timeline. Boss #3:The Alien Brain This guy is really easy all you have to do is enter the first door and kill the H2O Generator.Then head for the second one.Flip the switch on it and then the power of this huge boss will go down.Now head for the third one.Just walk into the room and then turn and run as the entire place will start to come down.This time it's a whole lot harder because you have to dodge sniper rounds.Just hit all the switches and the one in the room and blow the last generator.You will be sent to the present. Boss #4:Zero This can be Duke's final hour or his finest you choose.All you need to do is jump from every roof and get ammo for the BMF Thunderstrike this time it is weaker than usuall.Find the AGL-9 Launcher and the Havoc Multilauncher and start hitting him with the ammo you fire.Once you kill him he will blow into flames.You just saved the world. Now you can ask yourself."Was it Duke's final hour or his finest?" You can answer that yourself.
