Every chance you get, do not kill the human before you extract their brain stem. Extract their brain stem first as it will make the DNA worth more (25 instead of 10).The easiest humans to do this to are the scientists in the level with glowing cows.

On the mother ship hold L2 and press R1, R1, R2, R2, Left, Right, Left, Right, R2, R1. This gives you extra DNA. |
