Better DNA value

Hint by hey78900 on April 12, 2007  |  report this hint

Every chance you get, do not kill a 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. For some reason, if the person that is important to you dies (the person you need to abduct), extract their brain stem before you return to the Mothership -- the DNA is usually worth more. Additionally, it is rare to find humans with brain stems that are worth 50 or 100 DNA. Most humans have brain stems that are only worth 10 or 25 DNA. If you walk around Union Town, there will be humans with signs on them reading, "REPENT THE END IS NEAR". Those humans will have a brain stem worth 50 DNA. Also, Mystery Agents' brain stems are worth 25 DNA points most of the time, whether dead or not. The Psi G-Men are worth 150 DNA alive and 75 DNA dead.

After you complete the game all brain stems will be worth more when you use the anal probe:

Citizen from 10 to 15
Cops from 25 to 40
Repent Men (Union City) 50 to 75
Army from 25 to 40
G-Men from 50 to 75
When Pox has you take out the President, just run up, extract his brain, and take it to get 200 DNA; this is the most you can get from a single human. To get more DNA from humans, first use Hypno on them. For example, using Hypno on a town crazy (the one with the sign) can result in 200 DNA. To probe a Majestic Agent, cycle to your anal probe and charge it. Then, shoot the agent. Do this three times and the agent's brain will come out; it is worth 75 DNA each time.
