   Arcade game programming.
  hi,any one know any good sites / tutorials 4 programming arcade shoot ''em ups like Alien 3 The Gun?Thanx in advance. 
  So, you mean making a rail shooter?  Like Area 51, Time Crisis, etc.  As far as I know there are no tutorials on how to make this specific type of game, although the basic gameplay isn''t that hard.  If you''re making the game on for a PC you''re basically doing a bunch of mouse-hitbox collision checks. For graphics you could use 2D sprites (like in a 2D side scroller) or 3D graphics (like in a first person shooter.)  There are plenty of tutorials on graphics out there.  I suggest you look at the articles and resources section of gamedev.
