The developers of the vampire RPG The Blood of Dawnwalker note in the game's description that it is "the beginning of a saga."
Recently, in a conversation with IGN, creative director Mateusz Tomaszkiewicz shared:
"We have ideas for [continuing Cohen's story]. Let's just say, there's a lot of interesting stuff in this IP [intellectual property] besides vampires. There's a whole hidden world that we deliberately don't explore in the first game. We want to leave a lot of material for sequels, etc. However, we will leave hints of these things."
A sequel is not yet guaranteed — Rebel Wolves studio first needs to bring The Blood of Dawnwalker to release and the game needs to be successful.
