10 Video Game Moments You Weren't Supposed To See
5. I Suck At Making Maps - Doom 64
During the creation of a game, developers will often include notes only ever intended to be seen by their colleagues during production, who will find the note, address the problem, and in turn remove the note before the game ships.
Yet sometimes these communiqués end up being missed, as was most amusingly the case in Doom 64.
In numerous levels throughout the game, players are able to glitch the environment and discover pieces of geometry which aren't typically visible in conventional play, such as the wall behind an elevator in MAP03: Main Engineering.
In these areas, the expected wall textures are replaced with bright green images which read, "I suck at making maps," seemingly designed to stand out to the game's developers and indicate to them that these areas need to be textured before the game's release.
Yet because these areas also can't be seen when playing the game "properly," they were evidently missed by the devs and only discovered by players who broke the game, whether deliberately or not.
