How to Rush Effectively in Age of Empires 3

Steps

Gather starting resource crates, beginning with food, then wood

Use all starting food to create Settlers.

Put all Settlers on hunts and set the gather point for the TC to hunts

Continue queuing Settlers until you have approximately 10-11 queued

Ship 3 Settlers as your first shipment, or with Eastern civilizations, ship 300 food

While aging, shift about 7 Settlers to wood and the rest to food

Once in the Colonial Age, build 1-2 barracks close to your opponent's base (depending on civilization) and begin queuing up both heavy infantry (like Pikeman) and light infantry (like Crossbowmen)

Ship 700 wood for a more powerful rush or ship infantry for a faster rush

Continue training Settlers whenever possible, and put all new Settlers on food

Attack at 5-6 minutes with your army and continue to train heavy and light infantry

Add all new soldiers to your current army and have fun destroying your opponent's town

Musketeers Rush

Collect all Crates fast. Put all villagers to food (hunting using the hunt technique). Build one house and Market.

Try to advance to 2nd Age(200 Gold and an Outpost). You can do this as soon as you have 11+3 Villagers.

Send all the Villagers to wood. During aging, send a villager close to your enemy's base and put him on wood.

Continue collecting wood till you have 450 wood.

Collect Crates. Build Barracks, take the Fencing School Card, and build the outpost near Barracks.

Build houses. Put 4 on gold, 11 on food, and 3 on wood. Keep making Villagers and Musketeers.

Crush your enemy!
