Scud can be played with a lightgun or a controller, and having only played it with a controller, I think both peripherals would provide a similar experience. Playing this with a gun though, due to the long levels would probably end up giving the player a sore arm by the end of it. It is mostly a run and gun/side scrolling shooter, however with bosses and during the levels the gameplay switches to a first person shooter. It is a difficult game from the word go, with enemies entering the screen and shooting right away which makes it hard to avoid getting shot. The visuals aren't bad for a console which at times lacked in this department, as isn't the animation, but overall while fun for awhile, the repetitive action may not keep many playing until the end.
