Warhammer 40,000: Inquisitor - Martyr is presented as a top-down, slightly angled view which allows you to see your surroundings well.
With Mouse and Keyboard
If you want to change your point of view to better oversee the situation, you can rotate the camera by pressing down the mouse wheel and moving your mouse to the left or right.
You can also zoom on your character by scrolling the mouse wheel forward, and zoom out by scrolling backward.
Sometimes solid objects will get between the camera and your character. When this happens, the object is deliberately faded by the game so they don’t block your view.
