A collection of 14 printable stl files of biomass environment - not absolutely alien as many games would benefit from biomass scatter terrain as a result of radioactive wastes, mutation or other such themes.
Pricing of the set is essentially less than 1$ per sculpt, so a quite affordable set to cover even a very big gaming surface.
NOTE: People who have already bought my older alien biomass terrain should have all of these already downloaded - everything aside from the biomass mounds which is a separate post.
