Lunar Strain is a new Moon-themed episode megawad for Doom 2 designed for limit removing source ports (complevel 2) made by the various members of Doomer Boards, led by Matador. There are 22 levels plus a credits map but there are also two curiosities in the MAP31/32 slots. MAP31 is a demo map showcasing the new monsters/props. MAP32 is a color swapped version of MAP13.
