So, I haven't found a thread like this, and it's one of the things I'm most curious about.. What do you think the other three perks will be?
Many people say that one will be the Gunslinger who'll inherit Sharpie's pistol bonuses, I personally think there might be an Engineer class, who'll take over Support's welding, and maybe even be able to place turrets.
What do you lot think? What other things could Tripwire feature as a perk?
