Video games aren't that good at friends. Oh sure, they can be great for making them. Various multiplayer games have facilitated very real and valid friendships, but the games themselves scarcely contain an ounce of the same stuff in their characters. Bonds of friendship in-game are generally left to barks and grunts of command. Vermintide 2, despite taking place in the grimmest, darkest fantasy land there is, somehow manages the impossible and gives us a party of unlikely heroes whose bond feels terribly sincere.
Vermintide 2 does a great job of forcing players to work together no matter which hero you choose to play as. No weapon or class reigns supreme and only a combination will see you survive the hordes of rat-men. This isn't the first co-op game to, well, encourage cooperation. What makes it special though, what makes it so memorable and pleasant on every visit is the banter between characters.
In the fiction of Warhammer pretty much all these characters should be at odds with each other, forced only by circumstance to work together. The first game saw them working out the kinks in their relationship, but this sequel shows them having bonded, veterans of the perpetual apocalypse. Snarky remarks and in-jokes linger, they rib each other plenty as all good friends do. Equally though, they constantly throw compliments to each other. Hearing "Look at the elf go!" from the party's witch as you tear into a horde of baddies is the sincere encouragement that puts a little smile on your face.
