Tesla Bastion is a stationary 360-degree last-stand shooter you can play free in your browser with no download. You command a fixed Aegis Spire planted at the centre of the arena while drones swarm inward from every direction at once. You don't move — you rotate to aim, and the turret auto-fires wherever you point, so survival is pure target-priority and spatial awareness: read the whole ring, swing to the densest threat, and never let anything slip through to the core behind you. Every hit a drone lands on the core drains its HP and shatters your kill combo, so keeping the field clear matters as much as racking up damage. Chaining kills without letting drones through pushes up your score multiplier and charges Overcharge bursts you can unleash to wipe the screen when you're surrounded. Clearing a wave never means safety — it only summons a bigger, faster, tougher one, because the game is endless by design; the run ends only when the core finally falls. What carries between attempts is progress: every run banks Lumen that you spend in the Lumen Forge on permanent upgrades, so each defense starts a little stronger than the last. It's a tense, quick-restart arena survival built for chasing a deeper wave and a higher score.

How to play

You're fixed at the arena centre and the turret auto-fires — you only aim. Desktop: move the mouse to aim, or rotate with the Left/Right arrows or A/D. Mobile: drag anywhere to sweep your aim around the full 360 degrees. Trigger an Overcharge burst by tapping the bolt button, or pressing Space, F or Shift on desktop, to clear the field when overwhelmed. Don't let drones reach the core — each hit drains core HP and breaks your combo. Tips: 1) Always pivot toward the thickest cluster first; auto-fire chews through a line of drones, so facing density kills more per second than picking off strays. 2) Bank Overcharge for the moment you're ringed on multiple sides rather than firing it early — it's a panic-wipe, not an opener. 3) Protecting your combo raises your score multiplier, so a slightly defensive, no-leaks run often out-scores an aggressive one. Spend banked Lumen in the Lumen Forge between runs to start stronger.
