The Chestburster

The Chestburster is THE, I mean The ultimate weapon. It is a plasma weapon, uses energy rounds, is an automatic which uses 5 rounds per shot, and has a lethal embreyo which murders the person as a worm comes out of the opponents chest. As you use it you'll see. I had to beat Syra with the Captain, or the kings first form. It kills any enemy in one hit (I used it on Syra) and even if the person has the INVULNERABLE status. I know how to counteract the Embreyo, but you'll have to find out for your self. I got the captain or whatever by beating the game with the Fireborn. When you get it, only you can use it since it's on your data. I had to beat ALOT of people to get it. It will take over 6 months which it took me unless your quick. But, now that you know this, it will be fast.

Medal Codes

In multiplyer you can get medals. The more medals you get, you can have access to new skins and other cheats like infinite ammo.

Swim Faster

Frag Hint

First, get 500 frags. At the main menu, go into control pak. Go into copy players and copy the person that has 500 frags into all four slots. Then, go into load players. Load all four players into all four slots. Go back into the main menu and presto! the game "thinks" you have 2000 frags!

Infinite Health

First, get the minigun. Get the shield ability. Unlock the infinite ammunition ability. (Get 2000 frags and press Z at the main menu.) While you are playing, take out the minigun. Press B for the sheild ability. (I took a piece of tape and put it over the B button.) Now, you have infinite health! (Only downside is that it doesn't work in lava.)

Cheat Option

When you start a game the main menu will appear, when it does press the Z button. The cheat screen will appear but there will be no cheats. you have to get 2000 frags to get all of the cheats. If you get:

500 frags = 1 cheat
1000 frags = 2 cheats
1500 frags = 3 cheats
2000 frags = all cheats
