Steel Frontier: Turret Merge

Robots are advancing on the steel frontier, and your mission is to hold the defensive wall. Buy turrets, merge matching units, and move your strongest cannons into the active firing row. Place and upgrade mines, survive increasingly dangerous waves, and prepare for a slow heavy boss every fifth stage. The campaign contains 50 waves, 50 enemy types, 12 turret levels, and 6 mine levels. Defeat restarts the current wave without erasing your assembled defense or progression. Reach the final assault and secure the frontier!

How to play

Buy turrets with the cannon button. Drag two turrets of the same level onto each other to create a stronger unit. The two left columns are inactive merge storage and do not fire. Move completed turrets into the active row beside the wall; only this row attacks enemies within range. Use the mine button to place traps on the battlefield, and merge matching mines to improve them. Start each wave manually or wait for the automatic launch after 20 seconds. Keep the robots away from the wall and clear all 50 waves.
