Command an Army Update 3 Guide: New Units, Map, and Skill Tree

What's New in Command an Army Update 3

The latest update for Command an Army on Roblox has brought a wave of fresh content, heavily themed around the Mongol expansion. Players can now explore a brand-new map that introduces unique verticality and strategic capture points, which significantly changes how battles unfold.

Beyond the map, the developer has introduced a new Battle Pass, an AFK server for passive resource gathering, and critical gameplay adjustments. The AFK server, in particular, is a game-changer, allowing players to farm Gems and Skill Crystals while idle—with a small chance to hit rare rewards like 500 Gems or extra crystals.

New Units and Evolutions

This update focuses on expanding your tactical options with new units and evolution paths. If you are looking to shake up your army composition, here is what you need to know:

New Units

• Meridons: These units are proving to be excellent shield breakers. Community reports suggest they are highly effective at countering Spartan formations, as they can break through defensive lines that previously held strong.
• Laestrygonian Giants: As a five-star unit, these giants boast massive HP and damage potential. However, they are slow and have a slower attack interval. While they look intimidating, some players find them situational compared to more agile units.

Unit Evolutions

Evolution is essential for staying competitive in the current meta:

• Mace to Morning Star: This evolution grants your units more armor and damage output, making them a more reliable frontline choice.
• Pikeman to Phalange (Palang-guides): This is a significant upgrade for anti-cavalry strategies. The Phalange units feature long shafts that devastate mounted enemies. If you are struggling against cavalry-heavy opponents, prioritize this evolution.

Mastering the Skill Tree System

The Skill Tree feature is arguably the most complex addition in Update 3. It allows you to further customize your units with specific perks like "Reckless" for increased damage, "Parry" chances, or "Last Stand" for better survivability.

Important Tip: Based on player experience, the Skill Tree upgrades are not universal. When you spend Skill Crystals to unlock a node, that upgrade is bound to that specific unit card. If you evolve a unit or get a better version later, you may have to start over or reset. Avoid spending your limited crystals on low-star units; save them for your endgame four or five-star units to ensure you aren't wasting resources.

New Map and Tactical Changes

The new map introduces a layout that favors those who control the high ground. With multiple capture points, the map forces attackers to move quickly, often leaving them vulnerable to archers stationed on elevated terrain.

Defenders have a distinct advantage here. By placing archers on the mountain areas, you can cover multiple points simultaneously, making it very difficult for the opposing team to push through. When playing on this map, focus on securing these elevated positions early, as they provide the best line of sight and defensive coverage.

FAQ

Are Laestrygonian Giants worth using? They are powerful due to their high HP, but they are very slow. Many players find them overrated compared to cheaper, faster units. Use them if you need a tanky frontline, but don't rely on them as your sole damage dealer.

How do I get more Skill Crystals? Aside from using the codes listed above, you can earn them through daily rewards, rank wins, and by using the new AFK server, which offers a small chance to drop crystals while you are away.

Why shouldn't I spend Skill Crystals on low-star units? Because Skill Tree upgrades are bound to the specific unit card, spending crystals on a one-star or two-star unit is a waste of resources. Save your crystals for your best five-star units to maximize your army's potential.
