Requiem 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 and maps that can all do different things. Some of these things are compiled together to create a massive user-made campaign called a Megawad. One of the many is Requiem.

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

There is some lip service for a story, but there really isn't anything cohesive. The focus is on gameplay and design. This is designed by some of the biggest stars in the DOOM community, which is an achievement. The gameplay is about as cohesive as you can expect from so many authors that all have their unique styles.

There are maps that are smaller and simpler, focusing on the easy monsters, and then there are maps that focus on heavy encounters in large, wide open areas. There's something for everybody, and you can easily pick and choose which levels you want to play because of how there isn't really a story that you can get lost in.

If you're a DOOM fan, Requiem is a capstone of an era in DOOM map creation. With so many different styles, looks and gameplay scenarios, it's a great experience.
