I dunno if you guys have seen this before, but right click your Team Fortress 2 in your Steam Games tab and open up the User's Manual to get a nice easter egg.
Did it while installing.
Pretty nice, especially the advice about not standing in front of your sentry gun.
Now if only there were manuals for the other stuff, mostly for newbies who don't know all the intricacies of the game. Where does it say in-game how to activate uber charge? Or detonate stickies? It's just stuff you find out the hard way.
It's a shame the HL2 manuals don't have more in depth guides. Similar to that of HL1. That would have been nice. The smell of fresh booklet is one of the best of getting a new game.
