Iron Bastion

Overview

Iron Bastion is a top-down tank defense arcade game built around one tense question: can you intercept twelve-plus raiders before they shell the golden eagle at the bottom of the map? You drive a single defender tank through a maze of brick, steel, water, and bush tiles. Bricks shatter under any shell — yours included — so every shot reshapes the maze. Steel is permanent, water blocks tanks but not shells, and bushes hide whatever sits inside them. Raiders stream in from three spawn points along the top edge in three weight classes: fast light scouts worth 100 points, standard raiders worth 200, and heavy armor that takes three hits but pays 400. Clearing a wave earns a 500-point bonus and opens the next sector; eight sectors make the full campaign, and each one spawns more enemies, faster, on a denser map. Three lives, one bastion, no continues — but your best score persists between visits.

How to Play

Press Start Game, then drive with the arrow keys — the tank turns to face the direction it drives. Space fires a shell in the facing direction, with a short reload between shots. On touch devices, hold the on-screen direction pad to move and tap FIRE to shoot. P pauses and R restarts the run at any moment. Shells destroy brick tiles on contact, which opens firing lanes for both sides, so treat every wall as temporary. You respawn with a brief shield after losing a life; use those two seconds to reposition rather than charge. The run ends when the bastion is destroyed, when your third tank dies, or — in your favor — when sector eight is clear.

Tips & Strategy

Fight from the middle of the map, not the nest: the eagle's brick shell buys you time precisely because raiders stop to chew through it, and that chewing is audible progress you can count on while you hunt. Learn the three spawn lanes along the top edge and pre-aim them — a shell already in flight when a raider materializes is a free kill, and spawn-killing keeps the four-enemy field cap working in your favor. Heavies take three shells, so never duel one in the open while scouts slip past; the little ones are the real threat to the bastion because they arrive first. Resist carving shortcuts through the brick ring around your own base — every tile you remove is one less second of warning later. On water-heavy maps, remember that shells fly over water even though tanks cannot cross it, so you can snipe across a pond that forces raiders into a long detour. Finally, when the wave counter gets low, stop chasing points and body-block the approach lanes; a living tank parked in front of the nest beats a greedy one across the map.

What Makes It Distinct

Most browser tank games treat the maze as scenery. Iron Bastion makes the maze the strategy: destructible brick means the map you defend in wave eight is the one your own missed shots created. Combined with the spawn-cap pressure system — at most four raiders on the field, always replaced — every decision trades map control against interception time, which is the same tension that made the 1980s originals classics.
