Patches your weapons to hold more ammo, fire nastier stuff, and in the case of the fusion pistol, give you a mean little creature to kill for you.

A large net level designed for EMfH and KotH, consisting of two large 'arenas' and surrounding corridors on various levels. The smaller arena is lava filled with a slightly raised hill in the center, and the other contains more ammo and a shields recharger. Flow is very good with discreet teleporters to quickly transport you between the various corridors. Plenty of sniper points, and a few very handy, but well hidden secrets. Inspired by a dream the author had one night.

The basic premise of this net level is that it's set in a winter climate where snow and ice cover the ground, the result of which is that your traction with the ground is greatly reduced. It takes a while to learn the new techniques necessary (don't hold down the run key for a long time and use weapon recoil for maneuvering), but it can be fun once you get the hang of things. The map itself is fairly big (> 4 players would be best) and set up for multiplayer carnage with open large chambers on multiple levels, linked by elevators and narrow staircases.

A large, three-level parking garage. I wish the garages I park in had this much space to manouver... but the construction's pretty nice. The upper level's open air, the middle level's pretty well lit, if mostly enclosed, and the bottom level has a serious need for an electrician. Whatever your playing style, you should be able to find an area to excel here. Could be pretty slow for small groups, due to its very large size.
