After the credits you have a boss battle with your brother. He has a shield that you can not get past so what you have to do is when he throughs that big black ball at you you need to use your surge power to throw it back at him.Your enemy will catch it and throw it back at you.You will have to throw the ball at your enemy once more after he throws it at you again.Then he will fall to the ground.You will want to have your lift power so that you can lift the boulder in front of you and hit your enemy with them. If you do this right three or four times you will have defeated your enemy. Oh ya and if you are in critical damage there is a very long hall run to the back of it and you can not be hit so you're able to get your health back.

At the beggining of the game you will be able to choose your brother or fiance no matter who you choose they both die,but if you choose your brother you will have to fight your fiance on the last level or if you choose your fiance you have to fight your brother at the end of the game.

If you press up,up,down,down,left,right,left,right,white,black,X then the cheat menu will come up but there are actually 4 codes if you keep going down then another one will appear.

The codes are Blizzow mode where you can have all the powers at level 5 before you get them. Then there is god mode where you are invincible. Next is unlimited ammo where you can't run out of ammo but you will still have to reload and your power bar is unlimited. Last is the Uber mode where you have unlimited ammo and power bar but you don't have to reload.

Caution:sometimes when you enter the god mode and uber mode codes they can mess the game up temporarily like it will give god mode to one of the enemies or if you are hit once then you die instantly.
