Throwback turn-based RPG Sea Of Stars will get the free update that adds a local co-op mode next month, letting up to three players waddle through the game’s story side by side (by side). The update will also include commonly requested features, say developers Sabotage Studio, like tweaks to the combat and a “revamped prologue” that’ll see players able to get stuck into the action quicker. We’d previously heard about this update, but now we know the actual release date.
