A mix of Quake, Doom 3 and Duke 3D with a very unique, personal and genuine premise. It's pretty obvs where the quake influence goes, the author clearly loves Quake's brown textures but knows how to make the game not feel samey visually, it's more brown than Quake ever was but you'll never get tired of it. There's some Doom 3 in the more limited mobility and resources being scarcer than average for the genre. Duke 3D plays a big influence in the level design and soul of the game, levels feel like real places that are also made for a videogame like all good Duke 3D levels do, also the frequent and many elements of interactivity and humor which give a one man feel to game in the best possible way. The gameplay loop isn't as good as other games of it's ilk but it makes with level design and charm, most I can complain is that some projecticles might as well be hitscans but it's not a big issue.
