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. While it's possible some gamers are already aware of this visual cue, it's a secret that has largely remained undiscovered until now.
