In Open Beta you are able to drive a barouche carriage. As of Update 4, you are able to both drive and ride as a passenger in a carriage. The current barouche can seat two passengers and one driver.
In the village of Tyrehampton you will find carriages available in two locations. The main location is just outside of Mrs. Hatch's cottage, where you start the game. A carriage can also be found at the end of this road near the church. If there is no carriage in either of these locations, you must "Whistle" to call a new carriage over. Click the Carriage button in the Action Bar to call a carriage.
When you see a carriage you wish to drive left click on the carriage near the wheels. A new window will appear allowing you to select "Drive", "Enter" or "Send Home". If you click on "Drive" you will be seated as the driver, ready to go. If you click on "Send Home" the carriage will disappear back to the coach house. "Send Home" is useful if your carriage gets stuck in an unfortunate location or the carriage is otherwise not functioning correctly. If you would like to ride in a carriage with an available seat choose "Enter".
Click on the carriage wheels to bring up the window and left click on "Drive". As with walking, you control the movement of the carriage with the W, A, S and D keys. Press "w" to move forward. "Press "s" to move backward. Press "a" to turn left and press "d" to turn right. To effectively steer your carriage you will need to sometimes press the key to turn at the same time as the key to go forward or backward.
Note: As of Update 4 you must click the carriage button again to exit the carriage.
(There is now an "Enter" option between "Drive" and "Send Home".)
It is not necessary for driving, but you can look up and down by holding down the right mouse button and moving the mouse. You cannot look to the sides while driving a carriage.
If you are unfamiliar with this type of video game control driving a carriage might prove a bit frustrating at first. But please persist! With some practice you'll be trotting around the village streets in no time.
