I was checking the Warzone 2100 website, and bumped on a forum post from one of their developers who has made a multi-texture terrain blend render patch. With this patch the maps will have a more realistic and natural feel, instead of tiled patterns. This improvement takes Warzone 2100 a step closer to commercial RTS war games like C&C.

Also, a new version of the game is out, 2.1.1, although not using this patch. Maybe we'll get it on the next one?
Yeah it is a good game, but I've had problems with the mac version, meh.
