difFusion was built by Darkhorse as a multiplayer level with a strong emphasis on tunnel ratting. While I don't believe that it lends itself all too well to multiplayer games due to its size and complexity, it holds its own in terms of structure and texturing. I have yet to see a level where the lava/rock/concrete theme is executed as superbly as in difFusion. It's a fantastic blend of narrow tunnels, cramped rooms, large halls, decorated with pillars, rocks or concrete blocks sticking out of the walls, and signs of human existance in the form of grates or supports here and there. The texturing uses mainly brownish and reddish rock, with some lava ponds around. The level is completely irregular not only in its general layout, but also in its many naturally shaped areas. I never had the feeling of moving my ship in an actual half-natural, half-man made mine as real as in difFusion. My only minor point of criticism is the use of a moving rock texture where lava would have fit the theme and environment better. The screenshots can give an impression, but do not really do justice to difFusion - download and see for yourself.

Darkhorse calls this his best multiplayer level bar none, and indeed it seems to be close to perfect. The doors could give you some trouble if you're in a hurry, but not that much. Very irregularly shaped level with interconnected caves and lots of short tunnels.

Xenon appears coooooold. The whole level is an expertly designed shining ice cave, with ledges and corners in between that might make it a tad hard to maneuver at times - no big problem though. Again the proven recipee of interconnected halls that offer space for dogfighting is executed perfectly here. Darkhorse is even so extravagant to add a complete inaccessible river flowing through an ice chasm to the level just for looks (if only the spewn powerups don't end up here ...). Stunning.

Neon jumps at you with its colors, and it looks like Darkhorse let the bright ads associated with this gas inspire him here. Yet the level doesn't look ugly, and the coloring scheme has been chosen very well. Should be a fast paced level, as it is very open and has few corners to hide.

Epona II is a very diligently and skillfully crafted multiplayer level with a very irregular layout and structure. While this already lets it standout from the crowd, the completely monochromatic texturing makes it something truly special. Now this is not simply black and white texturing, but you will find all shades of gray from the Descent palette in this level. Even the force field sparks are silver. With this level, Darkhorse again qualifies himself as a top notch Descent level designer.
