Yeah I'm surprised more people aren't making that connection. Especially when people mention not being able to switch characters during the campaign.
People stupid. They saw co-op and zombies and immediately yelled L4D. Which told me those people really don’t even understand what L4D was.
This is Borderlands easily.
Pick a character with specific powers. Co-op, loot, light hearted/comical/stylish presentation.
It’s just got the Arkane emergent gameplay stamp on it.
Sounds absolutely glorious to me
