Secret Website and Code

On the Phobos Labs Sector 2 level, located in the Commons area, play all five levels of the Martian Buddy Blaster mini-game. Upon winning, you will receive a message in your personal PDA giving you this link: http://www.martianbuddy.com/blaster.html. This is one of two ways to get the code (634) for lockers #116 and #117 in the Delta Labs. The second method is to get the Patrick Hook PDA.
