New Guide!
The GoldFish (author of Stricken Souls and Droughtwinia) has written the first in what will hopefully be a series of modding guides for Darwinia.
The first guide can be found here, and is titled 'How To make a simple level from start to finish'. It covers all the steps to making a good level instead of just an island with some virii on it, including cutscenes, lighting and textures, and general tips on good practice.
So, for all you budding mod-makers out there, its well worth the read!
