Deviant Art user Elemental79 remastered a screenshot from Doom from 320 x 240 to a whopping 9600 x 7211 resolution in Photoshop. The project took him around 35 hours the complete but it looks really awesome! You can view the full 9600 x 7211 pixel image over here.
It is commonly agreed upon by all of humanity that Doom was the greatest game ever made. Okay, maybe not everyone. Doom was a PC game made in 1993 by id software. It was created by John Carmack, John Romero, Adrian Carmack and Tom Hall as well as many others. This is actually not a direct scene from the game but a composite. The Doom guy has only 1 rocket left and a pinky demon stands between him and freedom. If he shoots he's dead. These were some of the best moments in the game.
Each frame represents ten seconds of work. The image spans across 7 PSD files at a resolution of 9600x7211 pixels. The project took 35 hours to complete over the course of 8 days.
