Frictional/Grip's Earlier Work [UNBIRTH/FIEND,etc] + General game dev history thread

[Yuhaney]

Unbirth indeed seems to have vanished, but GamersHell says it had 1 download today. I am guessing it is still available there somehow?

Since you asked about history, I have something little. While messing with Fiend years ago, I found out some Half-Life themed test levels but I cannot remember where they are located at and how I was able to play them. Thomas confirmed that he made them, so they are "official".

For those interested, all of the games mentioned have their own dedicated sites.
Here are the links:

Energetic
Fiend
Penumbra
Unbirth
