There are two LGBT characters in the game.
The only way we know one is gay is through two voice lines you have a chance of hearing if you stand around him long enough in a patrol zone.
The only way we know the other is gay is because of the webcomic, which 90% of people didn't read. Hell, I play this game all the time and I haven't read either. The only reason I even know Ana is gay is because people keep f*cking complaining about it.
[i]"B-but, there aren't any openly [b]straight[/b] characters in the game!"[/i]
So? Who the f*ck cares? Do we need affirmative action for straight people now? Jesus Christ.
