I am generally suspicious of games that people say are "better with friends," simply because most things are. Wolfenstein: Youngblood isn't really just better with friends; it requires them. That's not a ding against Youngblood. The game has always been positioned as a cooperative experience. It's a co-op shooter. To criticize it for not being something other than that is unreasonable.
Taking a page out of cooperative games such as Left 4 Dead and their own Zombie Army Trilogy, Rebellion is bringing us today 'Strange Brigade', a new co-op third-person shooter that is also part of AMD's "Raise The Game" bundle for those purchasing a Radeon RX Vega, RX 580 or RX 570 graphics card.
