Drake Hollow

The fastest way to do this achievement is by starting a classic sandbox match. As soon as you load into the game manually save. After it saves move towards the camp and save the first two drakes. As soon as you save them wait a second and then quit to the main menu. At the main menu load the manual save of the last game. You must manually save every time you load into the map otherwise you will have to start a new sandbox match. Rinse and repeat the steps.
