Age of Empires II: Definitive Edition is the remaster that kept a 1999 classic alive and thriving into competitive esports. You guide a civilization from the Dark Age to the Imperial Age, balancing economy, military, and timing against a clock that never stops. The skill ceiling is enormous, but the core loop of build, boom, and attack is easy to learn.

This guide ranks the units that matter, explains what makes each one strong, and tells you which builds they pair best with.

Progression Path

The order you should acquire equipment as you progress:

  1. Starting gear → Enough to clear Arabia
  2. Arbalester → Your first real upgrade, available early
  3. Halberdier → Mid-game upgrade with good scaling
  4. Paladin → Best-in-slot, aim for this by late game
  5. Upgrade to max → The power spike from max upgrades is enormous

Practical Tips

  • Always upgrade your primary equipment before diversifying.
  • Match your equipment to your build's stat priorities for maximum scaling.
  • Keep your Town Center making villagers nonstop until you hit your economy cap.
  • Check our tier list for how equipment rankings affect overall build effectiveness.
