The game's narrative is heavily influenced by the player's choices, leading to multiple endings based on whether the player chooses to kill or spare the monsters they encounter.

- Web-based Ports and Clones: There are web-based versions and clones of Undertale that can be played directly in a browser. These might not offer the full experience or could be modified versions of the game but can serve as an alternative when the original game is blocked.
- Game Platforms: Undertale is available on multiple platforms, including PC, Mac, Linux, PlayStation 4, PlayStation Vita, and Nintendo Switch. If the game is blocked on a network, accessing it through a personal device or console might be an option.
