The mad "action-packed first-person shooter" Atomic Heart got a new trailer last week, but unfortunately it's still yet to receive a solid release date, with the window currently sitting at somewhere between September and December.

The good news is that we know it'll be coming to Xbox Game Pass on day one no matter what, and the developers have recently been talking to GamingBolt about what we can expect later this year.

According to studio Mundfish, an average playthrough of Atomic Heart will last around 20 hours. It's described as a game revolving around "high-octane action", reminiscent of DOOM and Wolfenstein, "but way crazier".

"Atomic Heart is an action game first and foremost. It’s very dynamic. You can definitely strategize on the go and pick various playstyles, but the core gameplay revolves around high-octane action. Think Doom, Wolfenstein, but way crazier."

Mundfish describes the "weirdness" of Atomic Heart as one of its creative pillars, teasing that it "features some truly insane concepts". The world concept has actually been in the works for over a decade at this point, and while it is actually an open world, the studio has advised it's going for a "believable and immersive" approach rather than trying to make the world overly large, so it's best to keep expectations in check.

We're keeping a close eye out for Atomic Heart later this year — it's one of our most anticipated Xbox games of 2022.
