This egg is kind of hard to find so keep looking if you don't succeed the first time around

1. Go to San Fierro.

2. Go to the center of Downtown.

3. Look for a building with french/glass doors on your right and left.(the center also has these doors but they're closed)

4. Face the building were the entrance is,(you should be facing South & the building that looks like a needle should be behind and to the left of you) there should be a concrete hill to your right going up and another on your left going down & nearby should be a restaurant.

5. Enter the building and when you do you immediatly see a flower bed with green plants on top, go around it and you'll see 2 identical signs on 2 walls, read either one.

It says, "Zombotech, sinister zombie research corporation, Welcome visitors". Go around and in between the to walls and you will see a giant copper D.N.A display. All of this is refering to Umbrella Corporation from Resident Evil
