hl. use the noclip 2 find out how hl was made. 4 instance. final battle. when u get teleported in2 the big room with a jump pad and an underwater bit twice, a garg appears. where did it come from? a box outside with the AAATRIGGER texture. teleported in the 2nd time u visit the room. the nihlanths teleport is complicated and how they did it is way beyond me but take a look around. try 2 find out how exactly the screen turned green when we teleported. it really helps make maps.
