Forgot to say that for testing d3xp you need to start it with:

doom3 +set fs_game d3xp

Mod doesn't show in the regular doom3 menu.

Talking about d3xp, there's some problem with visual effects specially when using the "hearth" weapon to slow things down: Things look upside down and very slow.

"Grabber" weapon has the effect of being up-side down too but no slowdown. Same happens with the regular "base" mod with doublevision effect. Could be an endian issue but I don't know for now.
