This game is just so good. Endless hours could be spent playing it. You get a full list of characters to pick from. Will you go with Samus, Link, Mega Man, or Luigi? Or maybe Bill from Contra, Ryu from Ninja Gaiden, or Simon Belmont from Castlevania? Whoever you choose, you will get their attacks and weaponry so Mega Man will shoot his arm cannon, Link can fire arrows or stab with his sword. The possibilities are salivating and the options and customization are second to none. This is one of the greatest flash games on the web today.
