The developer of Back 4 Blood has said it's discussing ways to address the lack of progression in solo mode after a player backlash.
Back 4 Blood players reacted negatively to a reddit post that revealed a message that pops up when you pick solo campaign (play on your own with bots) in Turtle Rock Studios' Left 4 Dead-style shooter.
"Uses solo decks created in the Fort Hope deck menu. Maps and objectives will be adjusted. Matchmaking and player invites are disabled. Earning Supply Points is disabled. Stat tracking is disabled. Earning progress towards Accomplishments is disabled."
