Had a blast with everyone's maps in this pack. Mapping for quad-focused combat is a tough challenge. Loads of additional monsters is to be expected, in order to balance the player's damage output, but it's tough to also respond to the player's normal damage intake, and dealing with spaces to keep them from being too crowded.
The result was interesting, to say the very least.
Riktoi's map was a personal favorite - not only is their approach to texturing and lighting unique (and awesome), but the visuals even serve as a way to balance the game play.
