While a Shadow Warrior 2/PAYDAY 2 crossover was probably wasn't predicted by anyone outside the dev teams, it makes a lot of sense. Both are first-person shooters. Both support up to 4-player online co-op. Both have "2" in their names... well, okay maybe that last one is irrelevant. Regardless, the Shadow Warrior 2 x PAYDAY 2 Crossover event is now live.
