RoachQuake: The BFG Turns Opponents into Roaches! — Quake 2 Mod, by David M. Pochron

"After the fall of Shub-Niggurath, the world which was the home of the Elder God Shrine was forgotten and fell into disrepair. Several hundred years later, as man expanded out into the deepest reaches of space, several mining expeditions came across this world and found the ruins of the former shrine. All layed claim to the artifacts at this site, and now battle amongst themselves to see who will get to uncover the secrets of the Elder God Ruins."

Quake and Conquer: a Real-Time Strategy Game set inside the Quake 2 environment

Take all the techniques you know about Quake 2 and throw them away.

Quake and Conquer is all about resource management and strategy. You can't resort to a gung-ho solo charge because - well, you just can't.

Your player is a disembodied essence wandering the levels. You have direct control over your creatures and machines through your crosshair.
