Fast forward to May 2016 and Dyack has resurfaced, now on YouTube.
He hosts a channel titled The Quantum Tunnel, which claims to offer "an unprecedented look into the making of film, television and video games".
In the latest Quantum Tunnel podcast, Dyack assures his viewers that Shadow of the Eternals is now alive again, although there is nothing yet to show which might back this claim up.
Dyack also commented on why the game's crowdfunding campaigns failed, where at one point he blames "extremely unethical" games journalism.
Back in the real world, we'll wait for more news on Shadow of the Eternals, should it ever materialise.
