If you host net games at all, you need this pack. (And if you only join others’ net games, you still need this pack to familiarise yourself with one of the most frequently hosted third-party packs on the metaserver.) It’s utterly massive, with (as of this writing) 44 levels from tiny to absolutely gargantuan, all gorgeous, all with fantastic flow, all with impeccable weapon and item placement.

I must confess I haven’t actually played all 44 of these as net games (again, there’s 44 of them!), but I’ve never had a bad experience with any of the ones I have. In my ideal world, we’d see the stock maps hosted on the metaserver a lot less often, replaced by maps from packs like this and Windbreaker’s Imperium.

While I’m at it, Ryoko’s Paradise Lost, Second Quest, and Red Spectrum also hold up really well. (Red Spectrum is quite architecturally simple compared to Ryoko’s later work, but still has great flow and weapon placement.) Grab those too.

Edit: Ryoko added six new maps for version XI that match his expected standard of quality, bringing the total level count to 50. Several other levels also have revisions, expansions, or bug fixes. If you have an old version of this pack, it’s worth getting the new one.
