This thing is addic­tive. Dis­cov­ery Chan­nel orig­i­nal­ly had this game devel­oped to help mar­ket and dri­ve traf­fic to its Future Weapons show.1 It was then port­ed over to the iPhone just a cou­ple of days ago.

I myself down­loaded it right before tak­ing the bus home from work. I usu­al­ly take a nap on the short-ride home but I just could­n’t put this down. I would def­i­nite­ly rec­om­mend this game as its free from the App Store. Here’s the direct link to the Can­non Chal­lenge’s App Store prod­uct page.2

The only down­side to the game was prob­a­bly its easy learn­ing curve (lit­er­al­ly). I fin­ished it in less than an hour…

I’ll see if I can post up some tip(s)/screenshots of my strat­e­gy and tech­nique lat­er =)
