A reference to unannounced future plans from inXile Entertainment are included
in an update from the developer about plans to support their two known games.
They brought this up in a backers-only update, but
Rock,
Paper, Shotgun spills the beans on the revelation (thanks nin), which
suggests another classic game is being revived by the folks behind
Wasteland
2 and
Planescape successor
Tides of Numenera. Along the way
inXile's Chris Keenan says they have "another RPG that has been passionately
demanded of us for a while now! It’s still quite early in the process, but we
will have more news on that in the New Year."
