Design and pilot custom-built vehicles to survive tides of 6,000+ simultaneous enemies. Harness real-time physics to engineer anything from armored rafts to agile flyers in this high-octane voxel roguelike. Your craft is your only sanctuary—arm it to the teeth.

Your perfect fortress against 6,000 reasons it isn't.Bastyrion: Endless Tide is a survival and engineering game where your creativity is the only barrier between you and an enemy scale few games have dared to attempt. Here, building isn't decorative — it's the essential tool to withstand the siege of up to 6,000 simultaneous enemies.In this archipelago, time is your enemy. Nightly skirmishes will test your defenses, but the true tide is unleashed when you challenge the corruption. When a core falls, the Tide — a ravenous mass of enemies flowing with a fluid, lethal pathfinding — will do everything in its power to swallow you whole.Key FeaturesThe Real Tide: Massive, Individual-Scale Pressure Forget small skirmishes. Feel the weight of thousands of individually-processed enemies behaving like a force of nature. Surviving demands a perfect synergy between an automated turret network and your ability to react when it matters most.<video class="bb_img" autoplay muted loop playsinline poster="https://shared.akamai.steamstatic.com/store_item_assets/steam/apps/4610700/extras/898ac03d36e48ade08a2799a6139e637.poster.avif?t=1778078690" width=800 height=450 ><source src="https://shared.akamai.steamstatic.com/store_item_assets/steam/apps/4610700/extras/898ac03d36e48ade08a2799a6139e637.webm?t=1778078690" type="video/webm; codecs=vp9"><source src="https://shared.akamai.steamstatic.com/store_item_assets/steam/apps/4610700/extras/898ac03d36e48ade08a2799a6139e637.mp4?t=1778078690" type="video/mp4"></video>Survival Engineering and Real Physics Design optimized defenses through an agile drag-and-build system. Physics is the heart of the game: every block affects weight, buoyancy, and lift. A poorly balanced design is a tactical vulnerability — your ingenuity will determine whether your fortress holds firm or collapses under pressure.Mobile Fortresses: Land, Sea, and Air Standing still is a death sentence. Connect movement and power modules to transform your base into an ironclad, a hovercraft, or a flying fortress. Link movement modules to escape the most corruption-saturated zones.Roguelike Progression and Upgrade Recycling Loot stackable upgrades for your character and vehicle. Thanks to the recycling system, you can dismantle what you don't use to craft targeted upgrades and optimize your build for the endgame. Progress from basic tools to Cobalt and Titanium technology.Brutal Combat: The Pilot as the Critical Factor Your turrets will handle most of the work — but not always enough. When the Tide breaks through the perimeter, you must step in directly. Melee combat is your last resort to protect vital modules and break enemy lines.<video class="bb_img" autoplay muted loop playsinline poster="https://shared.akamai.steamstatic.com/store_item_assets/steam/apps/4610700/extras/50eedadb33cfa3573e654ed509634f6a.poster.avif?t=1778078690" width=800 height=450 ><source src="https://shared.akamai.steamstatic.com/store_item_assets/steam/apps/4610700/extras/50eedadb33cfa3573e654ed509634f6a.webm?t=1778078690" type="video/webm; codecs=vp9"><source src="https://shared.akamai.steamstatic.com/store_item_assets/steam/apps/4610700/extras/50eedadb33cfa3573e654ed509634f6a.mp4?t=1778078690" type="video/mp4"></video>The Cloning Bay: Build Your Second Life In Bastyrion, respawn isn't automatic — it's a piece of engineering. Craft and integrate a Cloning Bay into your base. If your fortress falls and it isn't active, there is no second chance. Your survival depends on having built it in time.Core Bosses: The Trigger of Chaos Corrupted cores are multi-phase entities with unique mechanics. Destroying them is the only way to obtain progression gems — but beware: their death is the trigger that summons each island's Final Tide.
