1up.com has another entry in its 'Crucial Classics' series, and this one features a truly excellent NES title, Bionic Commando. From the article: "Most of Bionic Commando's innovations came in its hero's bionic arm. While the lead-footed character could not jump, a tap of the A button sent a moderate length of cable zipping out at a 45-degree angle, in hopes of attaching to anything vaguely resembling a platform. From there the player could perform a Tarzan-like swing to cross distances or simply retract the slack, allowing their commando to hang from the ceiling or even climb up to the next tier. The arm could also be sent straight up or horizontally, but Capcom's designers wisely made the useful angled shot the default."
