Grow Empire: Rome: How to Upgrade and Deploy Spartan Troops

To maximize Spartan troops in Grow Empire: Rome, prioritize gold investments into their health and armor before expanding squad size, and delay deployment until the enemy vanguard reaches the middle of the battlefield. Spartans function as heavy defensive anchors designed to stall enemy infantry and cavalry directly within range of your fortress wall, allowing archers, catapults, and heroes to eliminate incoming waves safely.

Spartan Upgrade Priority

Spartan upgrade costs escalate quickly per level. Investing in offensive power or larger squads before hardening base survival drains resources without improving holding power. Fragile, high-capacity squads deplete deployment horn gauges while falling quickly to enemy cavalry charges and elite commanders.

Allocate upgrade gold using the following priorities:

Ensure your existing Spartan squad can survive initial collisions with enemy vanguards before spending gold on additional troop slots.

Deployment Timing and Field Placement

Do not deploy Spartan units the moment an assault wave begins. Spawning infantry immediately causes them to march too far toward the enemy side of the map, isolating them beyond the protective firing arc of your wall defenses.

To position your frontline properly:

1. Watch the incoming wave and hold your deployment horn while the enemy approaches.
2. Summon your Spartan squad when the enemy vanguard crosses the halfway mark of the battlefield.
3. Form the shield wall directly beneath your wall-mounted archers and siege artillery.
4. Reserve leftover deployment horn gauge to summon a replacement squad if an elite reinforcement wave appears.

Engaging at mid-field keeps your Spartans in position to receive defensive hero support while concentrating opposing units inside your main kill zone.

Supporting Spartans with Artillery and Colony Income

Spartan units excel at absorbing physical damage, but their lack of burst offense leaves them vulnerable to attrition if enemy formations remain clustered indefinitely. Additionally, concentrated enemy archer lines can whittle down Spartans from outside melee range.

Support your defensive line through these operational steps:

• Trigger Hero Abilities on Clustered Waves: Use heroes with crowd-control, stuns, or area-of-effect damage while the Spartan shield wall pins enemy commanders and cavalry in place.
• Maintain Wall-Mounted Artillery: Keep catapults and ballistas upgraded to deliver continuous splash damage into the packed enemy ranks stalled against your shields.
• Conquer Map Colonies for Gold: Spartan upgrades require more gold than standard defensive wave rewards provide. Conquer cities across the campaign map to establish passive gold tribute, providing the recurring capital needed to fund continuous Spartan defensive enhancements.
