I just started the mid-game and really hit my stride. I tackled the Burger Bot quest and it should have been an even fight, but I absolutely demolished those guys, and I loved it. The chaos and action of that particular set of fights made me really want to share the experience with others.
Unfortunately, multiplayer progression will 100% destroy your single player campaign, and that’s to say nothing of lacking basic amenities like ingame voice chat. Seriously, Team Fortress 2 had comms back in 2008. For a game with so many social features, I’m incredibly surprised that multiplayer is so completely broken.
