Iron Marines+ Great Balls of Ice Veteran Guide

To beat the Great Balls of Ice Special Operation on Veteran difficulty in Iron Marines+, time unit movements between rolling ice boulder cycles, lure hostile squads into the hazard paths, and fortify your forward resource node before assaulting the northern base.

Surviving Rolling Ice Boulder Paths

Massive ice spheres spawn from elevated chutes and roll down designated lanes across the central map corridors. A direct hit deals lethal or catastrophic damage to friendly squads and heroes, but the hazard inflicts identical damage on Frostellian enemies.

• Never queue long-distance move commands across the frozen corridors, as pathfinding can trap squads directly in the line of an incoming sphere.
• Bait enemy units into the runway using your hero, then pull back to safety so the boulder wipes out enemy melee units and vanguard mechs.
• Advance immediately behind a rolling sphere once it passes your position to maximize your transit window before the next ball drops.
• Seek intermediate high-ground alcoves along the corridor edges, which remain completely immune to rolling damage and provide firing perches against native defenders.

Recommended Squad Composition and Hero Micro

Veteran difficulty waves combine ranged Frostellian gunners with armored melee brawlers. Assemble a force that balances front-line durability, structural siege range, and automated maintenance.

Keep your hero mobile rather than stationing them as a static tank. Use your hero to scout ahead, draw aggressive skirmishers into boulder paths, and deploy active abilities to eliminate surviving long-range riflemen. If individual squad members fall behind during a crossing, deselect the unit immediately to prevent the rest of the fireteam from doubling back into the danger zone.

Securing the Forward Ether Harvester

The primary resource bottleneck occurs at the first Ether Harvester node outside your main command center. Secondary lanes funnel regular enemy counterattacks toward this node, making mobile defense inefficient.

1. Deploy defensive turrets directly beside the harvester platform.
2. Select weapon modules based on incoming wave threats: autocannon gatlings shred fast assault units, while missile arrays eliminate grouped infantry clusters before they close distance.
3. Station an Engineer squad next to the turrets to automatically repair plating between attack waves.

This automated perimeter frees your hero and mobile army to focus entirely on advancing through the rolling hazard zones.

Assaulting the Northern Fortifications

The northern sector contains heavily fortified Frostellian bunkers, elite heavy units, and long-range mortar emplacements.

Begin your assault by inching your hero forward to grant line of sight on the outer perimeter without entering mortar range. Call in orbital strikes or support bombs directly onto clustered defensive structures to eliminate outer turrets.

Once the outer layer is weakened, push your armored mechs up the ramp to draw fire while snipers destroy remaining bunkers from maximum range. Spread your forces in a wide semi-circle across the northern platform; tightly packed formations take heavy splash damage from mortar shells and risk being forced backward into the boulder corridors during a retreat. Eliminate the remaining structures and defensive units to complete the mission.
