So i was doing the campaign on Ranger Hardcore and heard a few Red guards talking about the events of the metro 2033 mission "The Bridge" It turned out no matter if you did it in stealth or not, the mission ends up you killing all of the Reich and Red soldiers on both sides. I found kind of odd because every time i did the mission i did it in stealth, but I'm not everyone and the option probably was kill all of the soldiers
Or something killed them when you were already gone. TBH 4A just took the most common approach that 95% of players did and made it canon. @ 8:55 [YOUTUBE]I054eppHcks[/YOUTUBE]
I heard the NPCs talking about that as well, and I was like "YEAH, THAT'S ME THEY'RE TALKIN' 'BOUT!"...
LOL, I didn't even know there was a stealth route for that part. Fortunately I've got a 2033 game started where I left off with Bourbon leading us to that spot.
