Mega Man 4/Adapters, items, and weapons

Adapters and items
Rush Coil: You start the game with this. Identical to its incarnation in the previous game. Jump on Rush's back and a springboard emerges, allowing you to reach new heights with your jump.

Rush Marine: Get from Toad Man. Again, just like its previous incarnation. Can only be used underwater, in two stages only: Dive Man's and the first Skull Fortress stage.

Rush Jet: Get from Drill Man. Unfortunately, it has gotten a massive downgrade from the previous game, and Rush automatically goes in one direction when you board, rather than you having precision control over him. Still he can be useful in a number of situations.

Wire Adapter: Found in the Dive Man stage. By looking up, Mega Man can fire a grappling hook to pull himself to heights even greater than those reachable with the Rush Coil.

Balloon Adapter: Found in Pharaoh Man stage. Mega Man creates inflated platforms that can be used to reach new heights. Very useful in situations when you might need more than one jump or foot hold to clear an obstacle.
