Okay, so I'm having one of those annoying anxiety moments where I'm almost 100% certain of something, but I've reached the plateu where I can no longer easily verify my memory (you know, like when you go on vacation and think you left the oven on).

Getting to the point, I recently sold my copy of far cry 4 on eBay. The copy came with 2 codes that I never used, so I advertised as such. Now that its gone, I'm second guessing one of the codes, specifically the hurks redemption dlc. I'm 99% sure I never used that code, but I also recall meeting hurk in the main game: a cutscene where he's in the bed of a pickup truck saying he doesn't understand the guy who's driving it, even though he's speaking perfect English. Was this cutscene a part of the main game, or was it in the dlc and I am now fucked?

your memory is correct, it is part of the main game, I believe that is where you first unlock co-op. I don't think he is in any cutscene after that though
