A free, story-driven hardcore survival game for PC VR headsets with crafting, gunplay and mod support, set after an alien artifact crash-lands on Earth.
AB AETERNO is a story-driven survival game in the action and adventure genre from VRKemono. The developer calls it hardcore survival, mixing familiar mechanics with new ones designed for VR, and the listing summary names the STALKER series as an inspiration. It is distributed through SideQuest, though the listing has no first-listed date.
How it plays
You play James Danziger, a quantum engineer back from training on the Moon to join a recon team. Decades earlier, an alien Artifact crashed on Earth, shifted the world back in time and erased the event from almost everyone's memory. Only a few hundred people with experimental temporal implants remember. The Artifact now steers a shadow organization, the Earth Defense Alliance, which is at war with a breakaway faction called the Sons of Cain.
