Pause the game and wait a few minutes until a screen saver will show up.
To do this trick, you must first start a game in practice mode, then select MinaTek for your character, and any other character for the oppponant [ZipperHead works best]. Now, go to the level with the grinders and sawblades in it. It should be the second one from the left on the bottom row in the level select screen. when you enter the level, you might want to practice MinaTek's fatality.
The finishing move should be MinaTek lifting the other person into the air and biting off their head. Make sure that the cpu reaction is set to stand. now push the opponent infront of one of the Grinders. they should not go in, but start shaking. now do MinaTek's fatality. if done right, in mid kill, when MinaTek is stabbing the other person throught the chest, He should get sucked into the grinder. dont worry though, he will just come back out in the middle of the arena. now quickly look over to where ZipperHead or whoever was. he should be floating in the air for a moment, then get his head bitten off and he should be thrown away.

To check when your copy of Bio F.R.E.A.K.S. was created, quickly press the left C-Button immediately after you turn your system on (press it rapidly a few times to increase your chances). But you must stop pressing the button in order to view it. You will know if it is done correctly by the sound of someone laughing.
To make any character in Bio Freaks taunt at there opponet simply press LP and RK at the same time and then watch your character taunt his/hers opponent.
This code is very simple, and it works with every player in the game except Purge. All you do is start the arcade mode, then when you fight, pause and do as follows:
1. Go to the disables menu
2. Turn off shields
3. Go back to the game and do nothing but fire!
I was amazed myself when this turned out working. The only thing you have to watch out for is when Mutilater (the bad guy) shoots into the water. You have to get out quickly and keep firing, because there are parahnas in there that will eat you.
