Gears of War 3
The large, hulking soldiers from the Gears of War franchise are practically knock-off 40K Space Marines. Both groups of soldiers are covered in armor, fight hordes of aliens, and use chainsaw-like weapons during combat. Any Gears of War game is a solid choice to play after finishing Space Marine 2, but I’d personally recommend Gears 3. It plays a lot like Space Marine 2, still looks nice, and is backward compatible on Xbox One and Series X/S with FPS boost.
