those maps are confusing... which part is the place we can walk in game.. the black or the white... and why arnt all the spawns listed.. >.> maybe even a "best" spawn o.o
i think the black lines are the path you can walk on...white areas including spawns and walls.
i dont think those maps were made cause of the spawn points...they are just for getting out faster.
if you were ever lvling in lab 2/3/4 you should know the best spawns...there arent that much...
if you stretch them to about 10pc that would make them ideal minimap size... but what to name them i have no clue. maybe same name as their dmap files?
retouched labby L4 (but exact same form as posted here previously by jlthieman, except in gif so the filesize is 1/4th that ^^ )
on maps L2 and L3 black lines are the corridors
on retouched L4 white space are corridors
