Does Undertale need WiFi or Playstation Plus on PS4?
Does the PS4 version of Undertale need wifi or PlayStation Plus?
I made a mistake by buying PvZ: GardenWarfare on PS4, a game which can't be played without PS Plus.
Also, how can I tell if a PS4 game requires PlayStation Plus?
PlayStation Plus is only required for multiplayer games with online functionality.
Undertale is an offline single player RPG, so it does not require PlayStation Plus.
