Iron Caravan

Iron Caravan is a free tower defense on wheels: bolt turrets onto an armoured war-wagon, merge identical turrets into stronger ones, and hold the road through 20 raider waves to reach Haven. Play it in your browser on PC or phone.

Raiders swarm the wagon from every side. Between waves you stop at a station and pick one of three upgrades. Every few waves a boss blocks the road, and each one needs a different answer. Runs that fall short still earn blueprints for the Workshop, so every attempt makes the next one stronger.

Features

• Seven turret types (Gunner, Frost, Cannon, Tesla, Flamer, Railgun and Mortar) that merge up to level 5, then fork into one of two mastery paths
• Four boss checkpoints: Ram Juggernaut, Shield Hauler, Iron Juggernaut and the Warlord
• Station upgrades and road choices: every run builds differently
• Workshop meta-progression, twelve medals, Hard and Brutal difficulty, endless mode after Haven
• Guided first-run tutorial; plays on PC and mobile; progress saves automatically

How to play

Tap or drag a shop card onto the deck to buy a turret. Drag a turret onto an identical one to merge it. Fill the horn with kills, then press it (or Space) for Overdrive. Keys 1-7 buy turrets, P or Esc pauses.
