Questionable Research is a third party modification for Half Life 2. The project leader is Lambda
First we wanted to do an exploration through Black Mesa, but we changed it to "Blue Shard Research Facility", and exploring will be optional. The player is in a research facility, most likely on "another planet", and human mutants, clones of yourself and mutated creatures are attacking you. (more story will come)
The mod is in early development stages, and we are recruiting mappers and coders. As soon we found a coder and more mappers, we will start making serious progress.
