Once again proving that Waldo World was Bungie's most popular M1 net level, here's another version of that beautiful arena. This one's outdoors, and sports M2 niceties such as vistas, whistling winds, and shootable lights. Oh, yeah, and a shotgun...
A couple of converted M1 maps. There's an interesting port of Arena (looks like you're going swimming, but you're not), and a port of Halls of Death which is a bit hard to play in low-res due to the texture choices.
A mostly underwater map, which might be boring, except it comes with a physics model which allows firing of weapons. Lots of fun... (I wish the bobs would shoot underwater, too...) This doesn't crash my 68K machine, but it doesn't play, either-it just sits there (all sounds audible) with no visible image until I quit.
