The new Leviathan mode in Metal: Hellsinger is a whole lot of fun, though. It lets you jump into the game and engage with the combat in a way that feels less static than playing through one of the story levels again. The randomized boons make every run different and may sometimes push you to play with a different style than you normally would, and that's also a fun aspect of the mode. Meanwhile, the paid Purgatory DLC adds a great new weapon and a solid trio of songs, and between all of this, it's a decent excuse to spend six bucks and have a bunch of new fun with the game. I'm hopeful that the devs will tweak the ability to get those void crystals, though.
