Since I didn't find any of those names in the current info_hint from the Source SDK, then they must be included only in the alien swarm dev kit. How come is that possible... I am a bit confused.
And now about speculation.
Given the names
"Ep3 Brain Cover Position", "Ep3 Brain Regenerate Position"I think Valve is going to redefine what combat means by introducing something new. It's somewhat obvious that some advisors will try to fuck up Gordon's brain, or those entities refer to actual advisor entities. Then Gordon will use some kind of weapon to fuck with their minds.
I've gotta tell you guys, I stumbled on this page while reading the ep2 plot again and I am more curious than ever about where the hl story is going.
I really sense Valve is going to make a big announcement this year.
