About Undertale: Last Corridor
⭐️ Undertale: Last Corridor is a game based on Undertale and its AUs (Alternate Universes). You can play on the Chara Team and work together with your teammates to defeat your enemy — or play on the Sans Team, taking on your numerous foes with varying powers and movesets. 🏆 Win rounds to become stronger, gaining access to more powerful options to play with on both teams. Credit to the creators of all songs / AUs used in-game for their work. Credit to Toby Fox for creating Undertale. 📡 Join the communication server for ULC at the social link below!
