I’ve never actually played the Friday the 13th NES game, but I am familiar with its legacy, as I’m sure are many of you. If you’re unfamiliar with it, the game was labelled one of the worst of all time. That was 25 years ago, but that substantial amount of time hasn’t kept one fan from doing something that’s as crazy as it is impressive. I’m not sure what the split is, maybe 70/30 favoring the former.

In an effort to salvage at least a small part of the game’s reputation, TripleZeroFilms has gone and made a comprehensive guide for the game. Its 50 pages long and, according to its maker, took over 50 hours to create. Again, this is for a game that is nearly three decades old.

If you’re planning on playing it, this guide has everything you’ll ever need to know about it, including maps of its levels, comprehensive breakdowns of every weapon and enemy, and so much more. You can find it here.
