to spawn as a Hunter (no need for "give health" after the newest patch). You can find the advanced walljump techniques pioneered by Kaizoku in this thread [http://forums.steampowered.com/forums/showthread.php?t=770952]. A video showing some of the highly advanced jumping can be seen here [http://www.youtube.com/watch?v=EiLT3EQ6NDw]. You can see a jump curving tutorial here [http://www.youtube.com/watch?v=DSF94qv5oTI].
A Hunter City training map can be downloaded here [http://www.fpsbanana.com/maps/76114], good stuff.
