The first DLC for Borderlands is pretty solid. Coming out in the peak of the 2000's/2010's zombie boom of course borderlands needed a zombie DlC, and so the zombie island of Dr.Ned was born. It's pretty fun, gives you hordes of zombies to shoot through, but it doesn't offer much else on the gameplay side of things. The aesthetic is definitely the highlight, DLC 1 brings in some much needed colour to Borderlands and though it's not much it feels like a breath of fresh air, after the main game.
