3Back 4 Blood
If you’re a fan of Left 4 Dead, then Back 4 Blood is worth checking out. It’s essentially Left 4 Dead in everything but name – or at least, it tries to be. A few teething problems with its design means it doesn’t quite hit the highs of Left 4 Dead, but there’s no denying that shooting your way through zombie after zombie with your friends by your side is a hell of a lot of fun.
Back 4 Blood sees you make your way through various levels, all with hordes of zombies to mow down, barricades to put up, new weapons and upgrades to be found, and more. In each level, you’ll be seeking out a safe point, where you and your friends will take a short breather before heading out into the next zone. It’s action-packed and bound to get the adrenaline pumping, especially when playing with friends. So if zombie-killing is your thing, this is one of the best online multiplayer games on Xbox Game Pass.
