Unit Pathing & AI

Mastering unit pathing and understanding the AI's behavior is crucial for success in Age of Empires IV. While the game's AI has seen significant improvements over previous iterations, there are still nuances and strategies you can employ to optimize your unit movements and exploit enemy weaknesses. This section will delve into detailed tactics for controlling your forces effectively, minimizing wasted movement, and leveraging AI quirks to your advantage.

Optimizing Unit Movement

Efficient pathing ensures your units arrive at their destination quickly and safely, preserving their health and maximizing their impact. Poor pathing can lead to units getting stuck, taking unnecessary damage, or arriving late to a critical engagement.

  • Direct Pathing vs. Waypoints: For short, unobstructed distances, a direct right-click command is usually sufficient. However, for navigating complex terrain, dense forests, or enemy-controlled areas, utilize waypoints (Shift + Right-Click). This allows you to meticulously plan a route, avoiding choke points, enemy watchtowers, or dangerous patrols.
  • Formations: Always consider your unit's formation.
    • Line Formation: Ideal for ranged units like Longbowmen or Crossbowmen to maximize their firing arc.
    • Staggered Formation: Useful for cavalry charges to minimize splash damage from siege weapons or area-of-effect abilities.
    • Box Formation: Excellent for protecting vulnerable units (e.g., Monks, Villagers) by surrounding them with more resilient units like Men-at-Arms or Knights.
    You can set formations by selecting your units and clicking the formation icons on the bottom-left UI panel, or by using hotkeys (default: F1-F4).
  • Terrain Awareness:
    • Hills and Elevation: Units attacking from higher ground gain a combat bonus. Always try to position your ranged units on hills overlooking enemy positions. Conversely, avoid sending melee units uphill into a fortified enemy.
    • Forests: Forests provide line-of-sight blocking and can be used for ambushes. Hidden units within forests will not be revealed until they attack or an enemy unit gets very close. Use this to your advantage with units like Spearmen or Scouts for surprise attacks.
    • Rivers and Bridges: Bridges are often choke points. Be wary of sending large armies across narrow bridges without scouting ahead, as they can be easily bottlenecked and destroyed by siege weapons or powerful defensive structures.
  • Garrisoning: When units are low on health or you need to protect them from immediate threats, garrison them in Town Centers, Keeps, or Outposts. Garrisoned units gain protection and can fire arrows at nearby enemies. Remember to ungarrison them when the threat has passed or they are needed elsewhere.

Understanding and Exploiting AI

The AI in Age of Empires IV, while competent, has predictable patterns and weaknesses that can be exploited by a savvy player.

  • Aggression Levels: The AI's aggression often scales with its perceived strength and the difficulty setting. On higher difficulties, expect more frequent and coordinated attacks. On lower difficulties, the AI may be slower to react or less efficient in its resource gathering.
  • Target Prioritization: The AI generally prioritizes certain targets:
    • Siege Weapons: Enemy units will often prioritize your siege units (Mangonels, Trebuchets, Bombards) due to their high damage potential against buildings and groups of units. Protect your siege with melee units.
    • Monks/Religious Units: Conversion attempts are a high priority for the AI to interrupt. Keep your Monks well-protected.
    • Villagers: Raiding enemy Villagers is a common AI tactic to cripple your economy. Likewise, the AI will defend its own Villagers fiercely.
    • Key Buildings: Town Centers, Keeps, and Landmarks are high-value targets for the AI.
    Use this knowledge to your advantage. For instance, if you want to draw enemy forces away from a specific area, send a small raiding party to attack their Villagers, forcing them to divert resources.
  • Flanking and Encirclement: The AI can be susceptible to flanking maneuvers. Instead of a head-on assault, try to split your forces and attack from multiple directions. This can confuse the AI's pathing and force it to divide its attention, making it easier to overwhelm smaller groups of its units.
  • Scouting and Information: The AI often reacts to what it "sees." Extensive scouting with Scouts or even individual Spearmen can reveal enemy army compositions, building locations, and resource gathering points. This information is invaluable for planning your attacks and defenses. For example, if you see the AI massing cavalry, you know to prepare Spearmen and Pikemen.
  • Feints and Diversions: A small, aggressive force attacking a less critical part of the enemy base can draw AI units away from your main assault. This "feint" can create openings for your primary army to strike at a more vulnerable target, such as a Landmark or a key resource node.
  • Resource Depletion: The AI, like players, relies on resources. If you can effectively raid its resource gatherers (Villagers on gold mines, woodlines, or farms), you can significantly slow its production and research, giving you a long-term advantage.
