Once upon a time there was a post on the Valve ERC forums that initiated a cooperative single player mapping project. Eventually, that evolved into Project: Quantum Leap, featuring 20 maps by 15 different mappers. Radix was the map I made for this project. It was designed and built as an independent mission, so I have decided to release it as a standalone map.

You assume the role of a yet-to-be-identified character, thrust aboard the Top Secret Research Ship USCTS Chanticleer. Exactly what type of research takes place on the Chanticleer, or if indeed it is even a research ship, is unknown to all but the highest echelon. But you are about to find out first hand what secrets are aboard the Chanticleer, as you set in motion a chain of events the likes of which the post-Black Mesa world has never even imagined.

The ModDB page for Radix is here.

I owe a ton of thanks to the mappers and artists out there that make and distribute custom textures for use in the public domain. About 80% of the textures I used were non-HL textures. Thanks to these makers of the excellent textures I used, in no particular order:

I must also acknowledge the influence of the mod Natural Selection. A lot of the 'look & feel' of Radix are based on the atmosphere that NS is aiming for in its maps, and I was certainly inspired by various excellent screenshots posted on the NS forum.

Thanks to Artbroken, Zypher, EsBe, and Jabyaeye for beta testing, and to Adam Foster for other key pre-release suggestions.
