Well, it seems like Nicalis, and their "Binding of Isaac" franchise might have some competition, if lightly so. Out of seemingly nowhere "Metal Tales: Overkill" pops up with little to no marketing efforts, and probably for good reason. As it were this Euro-Metal roguelike unabashedly, and unashamedly capitalizes on the procedural dungeon layout, and features of Nicalis's cash cow. With an uncanny resemblance to the obvious source of inspiration it does little to deviate from that beaten path. Whereas Isaac treads his Mum's basement for salvation you are tasked, in "Metal Tales", as Axel or Eve to confront the evil that has consumed the Guitar Gods. All of which is done through dilapidated dungeon-like areas filled with the usual venue staples. Beer kegs, pinball machines, bars, and all that fun stuff plus some hazards to boot.
With blazing electric guitars in hand the two protagonists of the comic book intro story dive head first into these various concert stages, and festivals in order to deal with the manipulated mosher minions, headbangers, groupies, screamers, back-ups, flying beverages, and finally the mutated Guitar Gods themselves. A brutal gauntlet of music heavy scenarios with all the bits and baubles needed to best the baddest baddies. Everything randomly placed in themed rooms to help you on your metal af mission.
