Echo Grotto

Echo Grotto is a virtual reality cave exploration game. You descend through interconnected cave systems, using caving gear and tools to traverse underwater tunnels, huge caverns, crystal caves, ravines, sulfur pools, deep pits and glow-worm-lit grottos. Subtle random generation changes each cave system, while its individual caverns and passages are handmade and uniquely designed.

Explore the caves

Before entering a new cave system, you choose which gear to bring. Options include a grappling hook for movement, a headlamp or lantern for light, a snorkel for underwater areas, and a flare gun for illuminating distant places. You can also move with a teleportation system: throw a small teleporter lamp and travel to where it lands. Each lamp leaves a wire and trail of lights that you can follow back, like a caving string. Alternatively, use a pair of caving hooks to grab and move freely around the environment.

Play modes

In Experience mode, you can choose any gear from the start and explore as you wish. Game mode starts you with basic tools and has you search the caves for more. A simple currency system lets you use gemstones found underground to get better tools.

Scenarios and creatures

Scenarios change the gameplay in different ways. You can explore a flooded cave system, start from an alternative entrance or go in with only glowsticks. Some scenarios set special challenges, such as starting deep in a cave with only a candle that burns down over time.

Cave-dwelling creatures include snails, eels and wetas. You can choose which animals appear in the caves, or set the caves to have none.
