Similar to a pure RTS game, players can move their camera around the entire map and see what is happening in different locations of the map. However, the Fog of War will prevent the player from seeing most areas of the map, and will only be revealed when allied units are nearby, or with abilities that provide vision.
The camera can be controlled in 4 different ways:
- Moving the mouse to the edges or corners of the screen causes the camera to move in the direction of the edge or corner. This way, the camera can be moved into the 8 cardinal directions.
- Holding the middle mouse key and dragging the mouse grips and moves the game camera. The camera moves into the opposite direction in which the mouse moving. This way, the camera can be moved freely into any direction.
- Holding the assigned Camera Grip Hotkey + left mouse key and dragging the mouse. Functions the same way as dragging the camera with the middle mouse key, as an alternative (hotkey not assigned by default).
- Using the assigned hotkeys which are commonly assigned to the arrow keys or W,A,S,D. This way, the camera can be moved into the 8 cardinal directions.
Besides moving the camera, it is also possible to zoom in and out. However, this has no great use in matches, since the camera is by default at maximum distance and can only be zoomed in a bit. In spectatore mode, the camera is by default at the same distance as the camera is when playing. However, this distance is the minimum distance for spectators. As a spectator, the camera can be zoomed out by a lot, granting a better view of the map.
- Scrolling mousewheel causes the camera to zoom in when scrolling up, and zooming out when scrolling down.
