Altera is a military survival sandbox game set in a Central European landscape, focusing on base-building, crafting, and missions from NPCs. It features ranged combat against lifeless enemies and lacks zombies or competitive elements. The game has introduced "weaponized penguins," where players can equip penguins with military helmets and gun sights to engage in combat. Altera has been in development since 2022, originally conceived as a sci-fi game but evolving to a more realistic aesthetic while retaining the concept of humans and animals fighting together. The game has over 2,000 sign-ups for an upcoming playtest, and while a specific release date is not announced, it will debut in early access on Steam.
