Not sure where to put this, so I'll put it here... It's been said somewhere (I think) that the 'bullet' guns do the same damage and only change fire rate and bullet pattern. The wiki lists them as being the same damage as well (but then, it is a wiki). Anyway... when playing with default settings and such, I notice it takes the default gun two shots to break bricks and three to kill Goombas. The machine gun and spread gun break bricks with one bullet and kill Goombas with two. Likewise, the laser takes two hits to break a brick and three hits to kill a Goomba.. that is, two and three hits of one full beam, which can provide up to four.. meaning it's weaker than the machine gun and spread gun, which seems like an odd choice given the laser's limitations.
