Bionic Commando (1988) is a platform game with a hero who can't jump, but can quickly latch onto objects with his bionic arm. The name of the original (Japanese) version of the game literally translates to The Resurrection of Hitler: Top Secret. Nintendo censored the Nazi references for the North American version.
Author nEilfox's second contribution to Bionic Commando features inhumanly fast grappling and swinging. This run is an improvement of 00:03.33 seconds over the previous run due to better optimization and a new trick in area 7.
For more swinging goodness, check out these runs of the Game Boy and arcade versions. There is also an "all items" run which completes the optional stages as well.
