Age of Empires Mobile City Zeroing and Siege Guide

To completely deplete an enemy city's defenses and troop reserves—a process known as zeroing—in Age of Empires Mobile, alliance members must coordinate continuous rallies against a verified target. Executing a successful siege requires scouting the target's garrison readiness beforehand, breaking the primary defense with an initial main rally, and landing follow-up attacks before the defender can heal units, reset skills, or activate a shield.

Scouting the Target City

Before committing alliance rally slots to a high-ranked enemy, scout the city to confirm if its garrison can be broken through sustained attacks. Launching solo strikes against a target receiving heavy alliance support usually results in high-tier troop losses for the attacker.

Check the following metrics during intelligence gathering:

• Garrison Hero Synergy: Look for defensive hero pairings that mitigate incoming burst damage.
• Troop Tier Disparity: Confirm that your rally leaders possess a technological or troop tier advantage over the defending forces.
• Alliance Support Status: Check whether alliance members are actively reinforcing the target, as active defense significantly increases the damage required to achieve a zeroing breach.
• Anti-Scout Buffs: Account for items that hide true troop numbers, which can make fortified players appear less defended than they are.

Executing Coordinated Alliance Rallies

Depleting a top-ranked city's forces relies on momentum to prevent the defender from healing or adjusting defenses between strikes. Organize alliance assaults in structured waves:

1. Launch the Main Rally: Direct your strongest rally leader to strike first to break wall durability and defeat the primary garrison.
2. Time Secondary and Tertiary Waves: Schedule follow-up rallies to hit immediately after the primary battle concludes.
3. Sustain Pressure: Maintain rapid, consecutive hits so the defender cannot trigger shielding items, utilize defense skills that require reset periods, or port the city away.

Managing Siege Attrition and Retaliation Risk

Large-scale city zeroing demands significant resource expenditure and leaves participating attackers open to counter-attacks. To maintain army strength while taking down a high-value target, apply these operational controls:

• Rotate Rally Commanders: Alternate lead heroes between rally waves to prevent top commanders from becoming exhausted in a single push.
• Target Production Structures: If the defender cannot be fully zeroed in one offensive run, focus attacks on production and storage buildings to delay their troop rebuilding capability.
• Retain Home Base Reserves: Keep sufficient troop reserves in your own city while main forces are engaged in the siege to defend against sudden retaliation strikes.
