Thunder Tank: Iron Shield

Thunder Tank: Iron Shield is a casual game set in a post-apocalyptic wasteland. You pilot a battle vehicle through waves of enemies, collect weapon fragments, unlock gear and build a mobile steel fortress. Its combat combines bullet-hell action with a grid-based weapon arrangement system and idle progression.

Configure your weapons

Your vehicle has a limited number of grid slots, and each weapon takes up a different amount of space. You can unlock 13 weapons and combine them to suit each fight, balancing firepower and defense or choosing between single-target damage and area attacks. Loadouts matter when facing different enemy formations and level mechanics.

The weapons include machine guns for sustained damage and crowd clearing, flamethrowers for area burn damage against melee enemies, toolboxes for repairs, rockets for high burst damage, heavy cannons for long-range bombardment, shock towers that chain lightning for crowd control, and laser cannons that pierce in a line.

Vehicles and progression

New vehicles unlock after Chapter 4. Each has a distinct appearance, skill tree and upgrade path, with some focused on firepower, others on defense and survival, and others on resource acquisition.

Battles earn resources that you can use for equipment draws, which randomly provide weapons or accessories; coins to speed up weapon and vehicle upgrades; and fragments that permanently improve weapon attributes. This idle progression lets you build strength over time.

The wasteland

You drive across a post-apocalyptic wasteland of ruined cities, abandoned factories and dust storms. Along the way, you battle mutated creatures and mechanical enemies while seeking hope for survival.

Difficulty levels

The game has 20 difficulty levels, from easier introductory challenges to hardcore tests of your weapon combinations and resource management.
