As one who's made a few Infinity and 3rd party maps before, I've just come from playing the first level and the first part of the next. The level design and texturing looks good so far. I like how you put in secrets right from the start (won't spoil it).
Music is good. As for using existing assets; if the creators don't have a problem, I don't.
Glad you haven't thrown endless perpetually respawning Pfhor at the player; I tossed a scenario into the trash for doing that number on me.
Only suggestion so far is that the environment outdoor lighting (and shadowing) could be a little more detailed.
Its nice to play fun levels, and so far Phoenix has them!
A 35-level single player major conversion.
This scenario is difficult and action-packed; it features a full arsenal of new, powerful weapons, and more threatening enemies than you could ever want.
1.4 has new Lua features like a performance overlay, weapon buffs, a lot of little bug fixes; it also applies ammo capacity limits on Total Carnage. Requires Aleph One 1.5 or newer, probably!
