WARPSPASM is a 5-map Quake episode by ijed released in 2007. It features some of the biggest and most hostile maps I've ever seen in any Quake release. Most of these maps are massive and the monster count in them is insane, and of course it is all very hard. This episode makes use of the Quoth expansion by Kell, necros and Preacher. You can find more information about Quoth on this page: http://www.quaddicted.com/webarchive/...
Harsh-Angled Edge is just a little taste of things to come since it's a relatively small and easy map compared to the rest. This is played on Nightmare skill. Since the following maps are so big, it will take me some time to record/upload them.
