While playing through level 5 take a moment to stop and look through the alien telescope. To activate the telescope you must first destroy the BottRock Generator, and the panel on the ledge above the telescope. Now shoot the
telescope lens to move it into a position where you can look through it to see crack animator Russ Rice on the Bioware balcony having a puff with some Conehead visitors.

MDK 2 Development Team are Stars
While playing through level 4 don't forget to take a moment to gaze at the stars in the large arena with the three Poopsy Generators. Be sure to kill all of the enemies in this room first so you can star gaze without getting killed. Now, using
Kurt Hectic's sniper scope, zoom in on certain special stars in the sky (they are usually slightly pinkish in color). There you will find the crack team that made MDK2 possible gazing back down at you, along with their Wu-Tang Clan names.

The Hidden Castle in the Sky
In level 7as you are coming out of the tunnel toward the platform with the boss fight you will see two antennas which Kurt can jump up on. This can be difficult, but keep trying. Now turn around and face the tunnel that you came out of and jump to the roof of the tunnel. Now turn to your left and start shooting low at the sky with your Chaingun. You should eventually see your shots hitting something. It is an invisible walkway. Jump down on to it and keep shooting. Keep following the path of ricochet particles until you reach a little yellow square. It is a fan that will take you up to the next invisible walkway. Use your parachute and fly up. It takes quite a while to reach the top of the airflow, so be patient. Once you are at the top, rotate while firing your gun and look for the same ricochet effect and then
fly towards it. Follow this the same as before and eventually you will come to the hidden castle. Take a look around the castle and you might discover something interesting.
