If references are considered to be ties, then Yes. While I only met mention.
Warren even a scar on his head is, as in the first part, and by the way, the rocket that was the cause of the crash, isn't that in one of the endings the protagonist starts?
(Spoiler) the stranger is Warren the story here is not swason 1 there probably is another experimentation about the city government and Warren wants everything to tell the world.
the events of the second part chronologically occurs immediately after the first game of the series. there's even one of the quests you meet the main character of the first surge and audio messages associated with it.
