The aim of this mod is to add in the old locations from ShoC and Clear Sky, and to provide an enhanced and extended gameplay experience while (mostly) sticking to the vanilla storyline. At this point, the mod (v0.45 alpha)contains 37 locations total, approx. 200 weapons, lots of new armors, items, artifacts and anomalies.
Since a lot of people don't seem to have the patience to read the mod summary till the end, i'll put it shortly:
This and all the other new mutants are OPTIONAL.
