Darkwing Duck/The Bridge

"Quacker Jack and his henchmen are blocking the construction of the new bridge! You'd better stop him before someone gets hurt!" - Launchpad

Area 1
Run to the right and grab the Thunder Gas. Drop down into the pit, ignoring the pistol duck guy above, and grab the Gem. Jump onto the lever to drop a small I-beam and then jump on it. Kill the pistol duck guy just above, and then continue right.

Jump onto the hook, kill the pistol duck guy from there, then jump onto the platform and grab the Gem. Fall off the right side and grab hold of the lever. Use the I-beam to cross the gap, then jump onto the hook on the left. Head right, leaping from hook to hook. Remember that you can easily position yourself by jump straight up, then adjusting slightly so that you are closer to the next hook (it helps minimize the distance you have to leap). Once you reach the extra life, wait for the turtle racer to speed off to the left then drop down.

Hop over the two small gaps onto the first platform on brick background. Continue up, grab the Gem, kill the first bat by jumping straight up, then kill the second by holding onto the bottom of the beam the first bat hung on and just jump up and fire in mid-air.
