To celebrate the 20th anniversary of DOOM 2 in September 2014, Sourcerer compiled his best 32 maps from the last 18 years into a huge map pack released just before DOOM 2's anniversary.
Some Maps like 16 and the secret maps connected to it, 31 and 32, where chosen for their aesthetics, and consequently have pretty boring gameplay, shame to because with some modifications they could have been turned into something good.
