Too bad there wasn't a fourth ending that allowed you to kill everyone that kept nagging you during the final moments.
Getting through that glitch with noclip wasn't as easy as I thought it would. The problem was that the portal that Gordan supposedly jumps into was the reason why the game kept freezing every time I opened the door. I couldn't stare in its direction, which means I had to walk through the door backwards. What made this situation worse for me was that I was playing this for the first time, so I didn't know you weren't suppose to jump through Gordon's portal, which teleported me to nowhere.
Because I can't beat the game. Every time I enter the "We're Not Alone" chapter, the game freezes up when I try to open up the first door I see. I keep going back to earlier saved games to see if maybe it was a problem with the current autosave that happens a second before this problem, but the same thing happens every time. I could start a new game and play all the way back to where I'm stuck, but I'm not in the mood to replay the game for 2 hours right away...
Edit: I did some quick snooping around the web and found that I'm not the only one experiencing this problem. Apparently, the last Half-Life update screwed up Opposing Force.
A few days ago, I got bored, so I finally decided to download the original Half-Life off of Steam. Beat it yesterday, and it was pretty enjoyable. Though, the final few chapters had a lot of platform jumping that almost destroyed my left hand using the default button layout. Blu said months ago that I'll get used to the keyboard/mouse layout when I was playing another PC game then, but it's still annoying the crap out of me. Love the mouse for aiming and shooting, but the keyboard... ack.
And I finally just figured out how to putt properly....
