Be Quick or Be Dead

 Be Quick or Be Dead: Complete "The Outlaws" mission on Hard difficulty in less than 10 minutes. Worth 10 achievement points.

The mission time ends when the last enemy unit is destroyed. Highly recommended to start pushing forward early and build 2 barracks at the main base. Together with the 3rd barrack at the freed rebel camp it will provide enough forces to finish the mission in time. Do not forget to take advantage of the scattered resource crates, this will allow you to focus less on the base economy.
