Fear the Wolves, a post-apocalyptic battle royale being developed by the ex-Stalker folks at Vostok Games, will go from Early Access to full release on February 6. The launch will be accompanied by a "massive update" featuring a new artifact system, a new Wolf Matriach mutant, "anomalous lockdown areas," two new anomalies, and more. 

One of the new artifacts sounds like an interesting piece: It's actually the Wolf Matriarch's heart. You kill her and cut it out of her chest, and can then use it to summon friendly mutant wolves to help you out in fights. That's an odd way of hooking up with allies, but you can also pick up the hearts in the lockdown areas: They're highly radioactive, but on the other hand you don't have to hack organs out of corpses. The other artifact, "Spore," will enable you to briefly see enemies through walls.
