- The entire scheme revolves around a context-sensitive reticule that rests in the center of the screen.

- You'll use the two analog sticks to move around the maps--the left stick moves you around the field of battle while the right stick zooms you in and out.

- The reticule will change function depending on where it is and let you move, attack, or build with units.

- The main action button in the game will be the A button, which will let you select single units or structures by pressing it when your reticule is in position. Holding down the button will let you "paint" over units and add them to a group on the fly.

- When you've got a unit or structure selected, you'll use the right trigger to call up action or build menus depending on what you've selected. Once you have those fundamentals down, the game features an intuitive array of modifiers you can access that give you more functionality.

-The right bumper will let you sort units by type, while the left bumper will let you add and subtract individual units.

- The left trigger will let you select all units onscreen with the exception of builders.

-  The X button will let you return to a selected unit if you've moved to another part of the map with that unit still selected.

- The Y button is a very smart hotkey that lets you jump to events, such as attacks on your camps, instantly. If you find that the situation is in hand when you get there, you can simply tap it again to go back to where you were on the map.
