@Snickkers : if there's too much content for one sitting, you can always stop and play it again later. You don't need to sit down and play it all at once. :)
The trick to The Bowl is to move your base to the lip of the trench, to the right or left of the Drone upgrade. From there, you can quickly set up some collectors along the ridge, two or three blasters, then some generators. With this base in place, the rest of the level is pretty easy.
