Amnesia: The Dark Descent is fondly remembered as the terrifying title that changed the indie game industry, re-popularizing Survival Horror and influencing interactive media even a decade later. While there’s no denying the expert craftsmanship behind Frictional Games’ magnum opus, now that there’s a proper sequel on the horizon, I think that it might be a good time to look back on the ambitious games that helped to create the Frictional formula. The Penumbra series might not be as fondly remembered as Amnesia, but there’s no denying that it helped to lay the groundwork for modern horror gaming and is definitely still worth revisiting.
