In the beginning of the game you have to get your helmet and suit from your locker. Inside there's a cardboard box, which contains a small purple alien.
To open the box you'll need to get your pistol and grabbed the 2 extra ammo in the shooting range. After that go back to your locker and shoot EVERY SINGLE BULLET into the card board box.
Just keep shooting until you run out of bullets, the cardboard box will pop open, and a one eye purple alien stick out its blue tongue at you.
Also there is a hidden picture inside the blue shift's main directory, that picture is store in a folder which contains BS's entire menu text/logo...etc
Happy Easter hunting!
When you're being messed-around in the portal, wait until you're teleported into a semi-dark room. You'll hear some chatter coming from the window, so look outside...
