There is a seemingly unlimited supply of PSP homebrew games running on the Quake engine. What is less widely known, is the existence of a 3D engine that was nearly as successful. And was created specifically for the PSP.

Christoph Arnold (aka charnold) is the name of the German developer who made it. Originally an offshoot of his PSP Dungeons 3D project, it eventually grew to have its own 3D map editor for Windows and Mac.

The original Dungeons game later gave rise to Dungeons: Assault Run, last updated in July 2008. What is most remarkable, though, is that a few other homebrew developers made use of the engine for their own creations.

Serious Dungeons - by Be3f

Icon KillerZ - by VettaCossX

Project Savior - by EinhanderZwei

Radiosi Mod - by Drew Medina

Frack Mod - by Frack

Alien Huntress - by Adriano

Over the years, some of the mods were lost to history:

• Dark Dungeons by Be3f (Update: found and archived here)
• Halo Dungeons Vs by VettaCossX
• The Deadly Castle by BTR711
• Virtual Range Missions by BTR711

Other projects never made it past the concept stage.
