Forget the idea of a Russian BioShock: AtomicHeartis a wild, careening shooter that veers from aggressive silliness to dark horror in the blink of an eye, all of it experienced as a thick-headed Soviet super soldier who has no patience for any of this bullshit. It’s atonal as hell, and genuinely one of the funniest things I’ve played in years: This is Eurojank with a proper budget, and I love it.
