Same here, I suck too hard to play with others and I'd like a mod that lets AI mates follow you.

same me

A dude named Squiders makes several bot mods. Search it in the workshop.

There is a mod called "TROOPERS" in the workshop which says it is PVE, But can i get it to work on my server :( NO

Yes. There are some Aim-Mods on Real maps wirh AI shooting back. But no normal Singelplayer and No campaign, no story, no missions. Just aim training.

Best you get is the Squad Zues and Squidbots mod's by Squidders.

Granted, without a dedicated server running them, damage models are inaccurate.
