Legacy of Epstein is a survival horror game about finding a bunch of items and progressing a very engaging story.

There are a ton of hidden easter eggs and a bunch of methods you can use to speedrun.

First thing you have to do is unlock speed boost early. When the game starts, IMMEDIATELY skip the cut scene and get the main character to say his hidden dialog which only happens after being AFK in this game from having it open for 24 consecutive hours. Then when you come back, you have to glitch on top of the beater car, and then you will be able to fling yourself just by standing on top of the roof of the beater to the top of the map, where you will meet "The Great White" who will unlock modifiers for the game using the num pad (not sure how you use these if you don't have a num pad, sorry). The only keys that seem to work are 4, 5 and 6. 4 and 5 are both speed boosts, but 5 makes you go much faster than 4, and 6 gives you god mode. Now that you have these modifiers, they will remain in the game even if you close and re-open the game. Now if you do a run you can start it and immediately use these hidden modifiers!

Have fun!
