THE MISSION

Your fortress is not placed.
It is designed.

Bastion Grid combines tower-defense pressure with deliberate construction and direct command. Every wall, power connection, weapon, and resource structure becomes part of the position you must maintain through the next assault.

Build the grid

Place walls, conduits, resource structures, and weapons to shape a defensible network.

Command the defense

Manage construction, repairs, upgrades, targeting, and the timing of each wave.

Hold the Bastion

Adapt as enemy roles, damaged sectors, and limited resources test the position you built.

CURRENT PUBLIC DEMO

Command the defense from the grid.

Demo 21.0 brings the active battlefield behind the command interface, keeping the Bastion visible while you choose the next move.
