preview for MM10 the other day, but now we have some visuals to coincide with it):
The top left image shows off the new fire-based stage, said to contain conveyor belts that push you down, lava pits, and enemies that duplicate themselves.
Top right, the computer-themed stage. Mega Man faces off against the new mouse-pointer enemy who draws boxes and uses them as projectiles.
Bottom left, the desert-themed stage. Sandstorms make this stage a pain as they obscure your vision and push you into unseen spikes and traps.
The final screen, bottom right, the sewer stage features new slug-like Mets (not pictured).
