The Season 5 prologue levels, as well as their toned down version The Hunt For Greyhound One were released today as part of the Version 2.3 update. Other features include new characters and perks. To see what information needs to be added to the wiki, keep an eye on the Dalek Pathweb in the main page, and also on Category:Needs Improvement.
In commemoration of the update, TRG has released here a special code to unlock a single time crystal.
Next upcoming batch of content in the game is Season 8, which is set to be released around the same time as the eighth season of the Doctor Who TV show. Instead of releasing a singular pack of levels at once, a few group of levels will be released weekly hours after the original BBC broadcast of the episode.
