This is an illustration of one of the scenes from my Doom creative writing project, "Day of Wrath." It depicts the prototype "Doomsday" ATLAS mech engaging in warfare on Mars.
ATLAS stands for Armored Terrestrial Logistics and Attack System, and refers to the piloted mechs manufactured by the Amber Sun corporation in my story. Doomsday in particular is a classified project produced by both Amber Sun and the UAC.

"Day of Wrath" is mainly posted on SpaceBattles
