A huge arena surrounded by rising hallways. With big groups, this might be fun, but smaller groups would have a hard time getting close enough to kill. There's a switch in the central pillar which I don't understand at all... all it seems to do is make the upper hallways vulnerable from below. Since only those in the upper hallways can flip the switch, it seems, well... pointless. (I suppose it also makes the area around the hill targetable from above... but there is much more freedom of movement down below, so it's more dangerous to those in the passageways.)

A four level solo scenario. Mostly well-built, with nice architecture, and decent gameplay. Play would be better, I think, if it weren't quite so predictable.

A small mazelike map, with an embedded physics model that keeps you on your toes. (It's designed to be played solo-the SPN stands for SIngle Player Network.) You get one magnum (and, if you kill the infrequent vacubob, a fusion pistol), and your job is to kill as many bobs as you can. (There is no end.) Good for target practice... the bodies really pile up. Enough recharge canisters appear that you can keep going as long as you want to.

A six-level, action-packed solo scenario. This was released (and announced on alt.games.marathon) last fall, but there wasn't any active archiving going on at the time.

Bungie's Duality, modified with Bobs that shoot grenades or lava globs. The idea is to give people without access to a network the challenge of a net game. (SPN stands for Single Player Network.) Works okay, except that bobs will never shoot like real people... and not much care was taken with the physics model. (Although the shots are right, the sounds aren't... sort of strange when you hear pistol shots,and turn around to see lava globs coming at you.)

A nicely done outdoor canyon. Frenetic at first, because of the baddies waiting for you, but once they're gone, it's quiet again...There's a fast-moving river through the middle, with access to an underground cave, and plenty of nooks and crannies. A single manmade room overlooks the field, with teleporters to various high points. Probably needs three minimum to obtain decent carnage rates.

A large arena surrounded by multilevel ledges. Lots of weapons, lots of ammo, and lots and lots of bobs... smaller groups will have trouble staying alive long enough to kill other humans, because the bobs will gang up on you. Larger groups should be okay, though...

It's hard to know what to say about this one. It starts out slow, and there are lots of sloppy mistakes-spelling is atrocious, lots of untextured sides, baddies stuck in walls and ceilings...

A simple arena, in principle... but play it for a little while, and you might change your mind. The hill is accessible via 5D passageways from the outer ring... and you come out on the far side from where you started. Big weapons are on the hill, everything else is in the pit surrounding it... and to make matters a bit more complicated, 3x canisters can be found in sort of hidden corners (we found ourselves shooting at them just out of principle... you never knew when someone would be in there). Adds up to serious carnage, with anything more than 2 players.
