New Marksman in a Fantasy World (Fanfic) NMIFW

Welp I'm made a game developer thrown into a death game now the game is a real world. I'm fucking fucked but I got guns, and a boss monster. Just where is my damn sanity?

This is a fanfic of "The New Gate" its under novels because an option broke

**there will be random kinks thrown about but no scat or water sport, I have standards not THAT.**
