Drelvane is a mining tower defense game where you shape the battlefield yourself. Pilot your builder drone across a hostile planet, mine iron, crystal and obsidian, carve routes through the rock, and turn a fragile outpost into a fortress. There are no heroes here: your base is your weapon, and your drone is your lifeline.

Build your fortress

Deploy a standard turret and specialized defenses for splash damage, precision fire, anti-air, chain lightning, frost and mortar strikes. Combine them with tiered walls, gates, repair stations, batteries, Cores and a connected power grid. Placement, coverage and energy management shape every run.

Dig under pressure

Resources do not come to you. Leave the safety of your walls, drill exposed veins, collect fallen meteorites and return before the next attack. Every tunnel you open can become a route, a resource line or a weakness.

Choose your endless strategy

Play Classic for the original challenge. Rush creates two-front pressure with endless veins. Builder gives you more time and lower pressure to develop ambitious bases. Evolution lets you choose powers at hunting milestones and reshape your build as the run grows.

Take on survival missions

Enter handcrafted operations with their own maps, objectives and rules. Defend an HQ under siege, survive multi-front assaults, withstand EMP storms and adapt to new tactical constraints.

Build every run differently

Combine run-defining doctrines and artifacts with permanent Collection modules, a deep upgrade laboratory, an upgradable HQ, elite monsters, wave affixes and colossal bosses. The farther you push, the more demanding your defense becomes.

Compete and customize

Challenge the Google Play leaderboards across the endless modes, beat your own records and unlock new colors and chassis for your drone.

Made for mobile

Drelvane is designed for touch. Core gameplay is available offline; leaderboards and some optional online services require an internet connection.

On Drelvane, survival is something you build.
