Survive the Bermuda Triangle, explore mysterious islands, gather resources, and uncover a secret that should have remained hidden! Riley Ashford and her brother Jake are treasure hunters who are looking for an adventure deep within the Bermuda Triangle. Along with their pilot, Marcus Reed, they venture into the unknown — but a powerful magnetic storm suddenly strikes their helicopter. Jake disappears during the crash. Riley and Marcus are separated, and Riley wakes up alone on a strange island with no way back. Now she must survive. Explore mysterious islands, break objects, gather valuable resources, and use everything you find to stay alive. Upgrade Riley’s tools to destroy tougher obstacles and unlock new resources, then craft and improve powerful weapons to face the dangerous enemies lurking across the islands. But survival is only the beginning. Build and upgrade your raft to travel between islands and search for a way out of the Triangle. The journey won’t be easy — hostile rafts patrol the waters, and enemy crews will attack when you try to reach new islands. Defeat them in combat and keep moving forward to discover what lies beyond the next horizon. As Riley’s adventure starts, she encounters traces of an ancient tribe, a mysterious Long Fire, and a secret that has kept these islands isolated from the outside world for generations. Gather resources. Upgrade your tools. Craft powerful weapons. Defeat enemies. Explore this adventure game! Can Riley survive the Bermuda Triangle and find a way home?

About

Arcane Spire

Features
Read full description

Hold the last Spire against an endless galaxy of invaders. Arcane Spire is a fast, tactical tower-defense roguelite. Deploy planet-turrets across the lanes, read each incoming fleet, and spend your Power Surges at exactly the right moment. One tower stands between the swarm and the core. How deep can you hold? HOW IT PLAYS • Deploy planet-turrets: lasers, chain arcs, frost, burn, knockback and singularity vortices, each with its own role on the battlefield. • Draft a Power Surge between spawns: more power, crit, fire-rate, a fresh planet, or a screen-clearing Cryo or Gale pulse. • Call in five boosters mid-fight: Overdrive, Crossfire, Cryo Shatter, Ion Storm and Time Dilation. Each has its own window and its own way to turn a losing wave. • Cast potions on cooldown: Firestorm, Frost Nova, Healing Brew, Gale Burst. • Read the fleet. Shielded cruisers, armored juggernauts, fighter swarms and two-phase bosses each demand a different answer. • Clear the boss, bank your coins and shards, upgrade your arsenal, and push one world deeper. FEATURES • 10 handcrafted worlds, from the Astra Belt to the endless Void Abyss. Each world raises the difficulty band, swaps the enemy pool, and ends on a boss. • Roguelite runs. Every attempt earns currency toward stronger planets and permanent upgrades. You always come back sharper. • 28 planet-turrets to unlock, mix and master, from starter blasters to mythic singularities. Then mount moons on them for a second weapon layer. • Orbital Siege: a 150-level radial-defense campaign with its own upgrades, drafts and checkpoints. • Global leaderboard. Submit your best wave and climb the ranks. Optional sign-in keeps your progress across devices. • Snappy one-hand controls, built for quick sessions. • Play offline. The whole campaign is single-player, no connection required. FAIR & FREE • Free to play. Optional rewarded ads and in-app purchases (gem packs and a premium world), never required to progress. • No pay-to-win walls: every planet and upgrade is earnable by playing.
