Last week someone at Sony made the mistake of updating Guardians of the Galaxy: The Telltale Series' PlayStation Store page so that it claimed the first episode will launch on April 18.
Telltale Games has now officially announced that the first episode, Tangled Up in Blue, is set to launch on everything except Switch (where it will arrive later) on April 18. They've also told us to expect a new trailer and a few details this Thursday, so stay tuned.
