It's a speedmap. 

Flames designed the map with speedrunning in mind. He's done a great job... And it has a real vanilla feel, he's also done really well to jam all those secrets in such a small map. 

I did play this after seeing GGRC post a video about it. I'm not big on speedrunning or the lack of detail in speedmaps, but this one was alright. I did not get an impressive speed but managed to kill everything after finding all the secrets. 

So what's the deal with speedrunning? 100% kills/secrets as fast as possible? or just find the exit as fast as possible? Do people post their records somewhere? Are there Quake speedrunners who stream?

Is F14m3z on func? 

F14m3z (the author of this map) streams as he runs Quake on Easy skill:

Here is the web page where most of current speedrunning is happening:

In recent years the easy run of full game was getting most of the attention but single Quake levels are being speedrun also:

Check SDA for all the demos and records:

And there is also Quake Done Quick :)

Thanks. I had only really heard of qdq before. I never had any exposure to levels specifically made to speedrun. I might have to make one! I like how the records on speedrun.com are down to the millisecond.
