Mega Man Zero 3 is basically a refined version of Mega Man Zero 2. Most systems are modified to be friendlier and more customizable, like the new Cyber Elf system that finally lets you use them without being penalized. In terms of gameplay, Zero 3 is basically the same as its predecessors. New to the game is the Recoil Rod (replacing the Chain Rod) and the ability to equip different parts with new abilities (double jump is a fun one).

Overall, this is an excellent game. Completely recommended.
