Iron Brigade is a hybrid tower defense and third-person shooter developed by Double Fine Productions. Players command mobile trenches in an alternate post-World War I setting to defend against waves of robotic Monovision enemies known as Tubes. The core experience blends real-time movement and shooting with strategic placement of defensive emplacements, all while protecting a central base called the USS McKinley.
Gameplay
Each mission places the player in control of a customizable trench, a large mechanized walker that can move freely across the battlefield or anchor in place for focused fire. The trench carries a selection of weapons mounted on its hull, and players also deploy stationary emplacements that provide additional firepower or defensive effects such as repelling enemies. Scrap collected from defeated foes funds repairs, upgrades, and new emplacements during combat.
Before each mission, extensive customization occurs at the base. Different hulls determine weapon capacity and types, while collected parts unlock new options as the player gains experience. Both personal levels and regiment-wide progress unlock further equipment. The system encourages experimentation with loadouts that balance mobility, damage output, and defensive coverage. Up to four players can cooperate in the same mission, sharing scrap and coordinating emplacements and trench positioning.
Enemies advance in structured waves, with later threats requiring specific counters from both mobile weapons and placed defenses. The objective centers on preventing the Monovision forces from overrunning the base, though some missions shift the goal to destroying a key target. Repairing a disabled trench keeps the player in the fight without ending the mission.
Game Modes
The primary experience unfolds through a campaign of defense missions set across Europe, Africa, and the Pacific. These missions increase in complexity as new enemy types appear and environmental factors influence placement strategies. A separate Survival mode requires holding out against escalating waves for as long as possible, with one variant extending to 100 waves.
The Rise of the Martian Bear expansion continues the story on Mars and adds four new defense missions plus one dedicated boss mission. It also introduces two additional Survival maps, three new enemy variants, over eighty new equipment pieces, and a higher level cap. All of these elements integrate directly into the existing customization and co-op systems without altering the fundamental loop of movement, shooting, and emplacement placement.
Customization and Progression
Progression rewards players with new weapons, hulls, and cosmetic items after successful missions. Experience points accumulate toward both individual advancement and shared regiment goals that reflect recent cooperative play. This dual system keeps long-term engagement focused on refining trench builds rather than simple stat increases. Emplacements range from offensive turrets to utility options that alter enemy paths or provide area control, giving each mission a distinct tactical layer once players understand enemy behaviors.
Is It Worth Playing?
Iron Brigade delivers a focused hybrid of action and strategy that rewards coordinated play and thoughtful loadout choices. Its campaign and Survival modes provide clear structure for both solo runs and group sessions, with the Martian Bear content extending the experience into new environments and challenges. The game remains available on PC and continues to appeal to players who enjoy blending shooter mechanics with tower defense planning. Those seeking a polished co-op title with meaningful customization and wave-based combat will find consistent value in its systems, while the absence of ongoing seasonal content means the experience stays exactly as released.
