It's been nearly 30 years since the NES classic Mike Tyson's Punch-Out!! was released, and today a Reddit user has found a secret that's been kept hidden all these years.
Reddit user midwesternhousewives discovered that, during the second fight against Piston Honda, as well as the second Bald Bull fight, a bearded man in the crowd will duck as a visual cue. These fighters can be instantly knocked out if you time Little Mac to punch at that exact moment.
Punch-Out!! is all about precise timing and keeping a look out for visual cues such as this one, and it's interesting that this particular secret has been largely undiscovered until now.
