Coming December 2025
It was first reported to be a third-person spin-off set in the Perfect Dark universe with a male lead but not a direct sequel or a game starring Joanna Dark.
Looks like they've already rebooted it since then like Fable
From what I gathered over the years
Velvet Dark - Rare - cancelled in 2001
[Let's do a prequel first!]
Perfect Dark 2 - Rare - cancelled in 2007
rebooted as...
Perfect Dark Core - Rare - cancelled in 2009 (Seavor leaked the entire script on Twitter)
Perfect Dark - cancelled in 2016
(this was started after the KI reboot was a hit and started around the same time as the new Gears trilogy but we never figured out who actually was the developer behind it but it wasn't Rare)
Perfect Dark TPS spin-off - The Coalition / Rare / The Initiative - cancelled in 2018, rebooted as...
Perfect Dark - The Initiative
<- you are hereConsidering Zero started out as a prequel and not a sequel around the same time they started the sequel/spin-off they've been trying to get a sequel off the ground for 20 years.
