Couriers is always worth getting, as it greatly increases the durability of all of the three Inca units who form the core of any well-organized Inca army. It should be treated as a Blacksmith upgrade, and considering its cost, it should be researched after Plate Mail Armor and Ring Archer Armor, since its cost is higher than both Blacksmith technologies combined.
Also in The Forgotten, where Couriers gives speed instead of armor, researching Couriers is a must, since it increases the fighting abilities of all affected units at a low cost.
Team bonuses Edit
The Forgotten Edit
The African Kingdoms Edit
- Couriers now gives +1/+2 armor instead of +10% movement speed.
Rise of the Rajas Edit
- Prior to The African Kingdoms, Couriers gives additional speed to three different Incas units. This is probably inspired from chasquis, the runners in Inca Empire who were known for their ability to travel at long distance to deliver messages.
