Gonarch’s Lair is 3 large maps. Not 1. It’s very close to Release Candidate ready now, as is the Xen chapter.
This leaves us with Interloper as our final major piece to finish. This is why our announcement is exciting.
We project that we can complete Interloper in roughly a similar sort of timeline to Gonarch’s Lair (probably somewhat longer).
Nihilanth and Endgame have been ongoing processes and as each are only one map we consider them separately to everything else - they haven’t been part of our focussed development process in the same way that everything else has. They’ll get finished alongside Interloper, undoubtedly. That, and Endgame is already mostly done, pending a final pass.
