Suicide squad: kill the justice league is my most recent co-op. Way better than expected also, it puts the Avengers game to shame.

Vermintide 2 is one of my favourite games of all time though. I've never uninstalled it in the past 5 years or so.

One of the best things about Vermintide is that only 1 person in the party needs to buy DLC and you can all play it together 👌.
