Need help gunslinger achivement metro last light?

It sounds impossible but he's right, I'm sorry

-Rep After a good game in csgo, i added him because he seemed like a cool guy. We got chatting, over the next couple of months we became good friends. Lots of banter, lots of great CS and most importantly true friendship.
I invited him to my house for a csgo lan party. He said he was coming so i was looking forward to meeting him in real life.
When he arrived at my house, he pushed me against the wall and started nibbling my ear, i felt his hard ♥♥♥♥ push against my leg. I punched him and then 1 tapped him. Turns out he was gay. Don't trust this guy
