Rockman X 3Free
Rockman X3 follows in the tradition of both the original Mega Man series and the Mega Man X series as a standard action-platform game. The player traverses a series of eight stages in an order while gaining various power-ups and taking the special weapon of each stage's end boss. Mega Man X3 is the first game in the series in which Zero is a playable character in addition to X. Like its predecessor, Mega Man X2, Capcom included the CX4 chip to allow for some limited 3D vector graphics and transparency effects.
