Speed of Doom

Speed of Doom is a 2010 megawad by Josh Sealy (Joshy) and Darkwave0000, which requires a Boom-compatible source port to play. It features 33 levels, including one level accessible only through cheating, inspired by Plutonia, Plutonia 2, Hell Revealed, Hell Revealed II, Alien Vendetta, Kama Sutra, Scythe and Scythe 2.

The bulk of the soundtrack was composed by Stuart Rynn, although five tracks were contributed by James Paddock, and 14 other tracks were taken from various sources.

The end of a map often looks like the beginning of the next one, as if you could copy and paste them all in a giant map.

The Story
You wake up with a sore head inside a cave that you and other marines were checking out after hearing suspicious noises. You look up to the sky and realise it is all green as a result of a foreign bomb that exploded. The aftereffects has consumed the whole planet. Fortunately, you are immune to the chemicals, but not so much for the others. Upon exploration of the infected bases, you confront very familiar enemies that have seemed to spawn or mutate all over the place. Apparently, Hell is back and just wants more and wasted no time initiating more chemical attacks on other bases. Eventually Earth will be hit and it is up to you, the lone marine to slow down and stop the ever-increasing speed of Doom that Hell will unleash.

It is up to you to determine the speed of your doom before the inevitability of time...
