To reach 60% map conquest in Grow Empire: Rome, conquer weaker peripheral settlements before attacking central barbarian strongholds, deploy dedicated siege units to tear down fortified colony gates, and immediately suppress rebellions to preserve your territorial percentage and tribute stream.

Selecting Campaign Targets

Do not advance directly into high-tier Germanic territories. Rushing fortified central provinces results in heavy casualties against high-level garrisons. Instead, expand across softer peripheral regions such as coastal Gaul and Iberia to build steady map completion.

Before launching an attack, review the target settlement on the campaign screen:

  • Defender Rating: Avoid settlements that significantly out-level your current frontline troops.
  • Wall Tier: Target settlements with wooden palisades first; heavily reinforced stone barriers require dedicated siege investment.
  • Archer Tower Count: High tower density quickly decimates unprotected assault waves.

Completing regional clusters of easier settlements expands your empire's map percentage quickly and establishes the steady gold tribute required to finance higher-tier sieges.

Assembling an Invasion Army

Unlike standard wave defense, colony invasions require troops to cross open ground under relentless tower fire. Reaching the 60% mark requires transitioning away from basic infantry rushes to a balanced roster built around structural demolition and damage mitigation.

Roman ArchersRanged suppressionWall garrisonsClears enemy archers and spear throwers from palisades
Shock CavalryFlanking speedBackline reinforcementsIntercepts enemy counter-charges outside gates

Heavy Legionaries and Spearmen absorb incoming missile fire, while Battering Rams and Catapults dismantle gates and towers. Roman Archers remove defending marksmen to prevent continuous attrition during the approach.

Timing Tactical Skills at Colony Gates

The choke point at the colony gate is the highest-risk phase of an invasion. Units bunching up against an intact gate take severe area-of-effect damage from defending towers.

  • Hold offensive bombardments: Save high-damage abilities, such as boulder strikes and archer volleys, until the gate collapses. Firing them against stone walls wastes their damage, whereas dropping them on the defending garrison as it charges through the breached entrance wipes out the counter-attack immediately.
  • Trigger combat banners on impact: Activate combat buffs the moment your Battering Rams contact the gate to accelerate demolition and minimize the time your frontline spends under tower bombardment.

Reinvesting Tribute Gold

As you approach 60% map control, passive tribute income from conquered settlements surpasses defensive wave gold. Funneling this revenue back into your assault capabilities keeps your army ahead of rising colony difficulty:

  1. Frontline Health: Upgrades the survivability of infantry against concentrated tower fire.
  2. Siege Engine Damage: Increases gate demolition speed to reduce choke-point exposure.
  3. Hero Abilities: Enhances the area damage and control needed when breaching inner garrisons.
  4. Colony Administration: Raises base tribute output across conquered cities to fund ongoing military upgrades.

Suppressing Colony Rebellions

Subjugated provinces periodically rebel. If a rebellion succeeds, that colony is removed from your territorial roster, reducing your conquest percentage and halting its tribute payments until recaptured.

To prevent rebellions from stalling your campaign progress:

  • Prioritize high-yield settlements: Retake high-tribute provinces first to protect your economy.
  • Counter-attack immediately: Use your upgraded invasion roster to retake rebellious towns in a single assault before they disrupt forward progress.
  • Treat suppression as maintenance: Monitor the campaign map between invasions to ensure your territory remains secure and fully productive.
