by Xanatos. The Gman Squad is a sketch comedy/improv machinima series that takes place in Half-Life's very own Black Mesa. In it you will find the squad's adventures at the doomed complex and also many miscellaneous segments and comedy bits. In this second episode, The Gmen find themselves in the wake of a resonance cascade, stuck right in the middle of the black mesa carnage where they left off. Now they will cross paths with Gordon Freeman and continue to wander aimlessly, eventually hoping for some sort of an escape from headcrabs, zombies, scientists, security guards, bullsquids, vortigaunts, barnacles, and that invincible guy in the blue suit adjusting his tie on that catwalk above. New segments include "Science" and "Gman Squad Trivia".
