Gman is not some stock villain. That's what's great. He's a morally ambiguous character with complex motivations.
You'd take him out of character just for some cheesy boss fight?
Antlion Guards scared the shit out of me until I fought them a few times on Gmod
That sound coming after you in the tunnels...yikes
The Ichthyosaur sucks but you can usually sit outside the water and use the grenades or pistol to kill it.
Gman theorizing has pretty much gotten to the saturation point with the info we've got...it's really vague who he could be, that's why ppl get pissed off at these threads.
There won't be much new stuff about him to discuss until Ep 3 comes out.
Eli's really nice, but he's not a deep character. He's just into helping people, protecting his daughter and Doing Teh Right Thing For Humanity.
He's probably got the purest motives in the whole series.
