Delta Worlds brings the essence of Undertale to Roblox but spins it into something entirely its own. While the fighting, mercy system, and item mechanics may feel familiar, the game has its own unique story, NPCs, items, and plenty of secrets to uncover. It’s a fully 3D experience where your main goal is to collect shards to stop something called “the event” from happening. Along the way, you’ll encounter side stories that slowly build up to the big moment, keeping you engaged throughout.
