Go to the library and go behind the main stairs to where the protestors
are (in the middle). Go behind the stairs and look for some grates in
the wall. Kick the grates out and go through. You'll drop a pretty long
distance after you walk a few feet. Then follow the pipe the rest of the
way. You'll see a pit. DON'T DROP DOWN! There are invincible dogs down
it that are guarding a SiC Vest (200 armor)! On one side of the hole
there is a small, square passage. If you can, drop down and run into the
passage (a good idea is to distract the dogs with doggie treats or
cats). Then, grab the SiC vest in the corner and head for a pipe in the
middle of the hole with a ladder on one side. Climb up and get out. If
you did this right, you'll come out slightly damaged with more than 100
armor and still good health. However, you could cheat and get millions
of cats or doggie treats (or both) to distract the dogs so you'll never
get hurt!
