You Dig 1.0

DOOM is one of the oldest FPSes in existence, and its engine is famously so robust that it can run on pretty much anything and also create pretty much anything.  From FPSes to RPGs to companions to a city living game, it has a ton of different mods that can all do different things. One of the best ones out there is You Dig, a mod that changes so much it may as well be a whole new game.

To install You Dig, you need to have ZDoom and move the WAD file into the GZDoom folder, which is pretty par for the course for DOOM mods.

This is one of the most unique mods out there, as it completely changes the baseline code. The premise of this mod is simple. You're stuck in a cave with a shovel in your hand, and you have to dig your way out. This is the main gameplay loop of the game - you can dig out any of the walls around you within reason. They're coded as enemies and usually have items or enemies on top of them. This makes the map play out like a first person minesweeper.

Each room is divided by walls and are also usually filled with enemies, so the combat in this map is usually separated between incidental dug up enemies and massive rooms full of them. That gives this map a very special pacing. Overall, if you're a DOOM fan, you should definitely give You Dig a download.
