The Heartbeat mechanic will apply to Ellie and the enemies and as characters sprint around or engage in combat-, their heartbeat will increase which will result in heavy breathing, which can expose both Ellie's and enemies' position.
As we get closer to the official release date of Naughty Dog's action-adventure The Last of Us Part 2, the developers have been sharing a lot of new details about the game and we also got new gameplay video, showcasing some of the biggest changes in the sequel.
Today, we have a look at the brand new mechanic in The Last of Us Part 2. In the latest interview with Polygon, co-director Anthony Newman revealed Heartbeat system. According to Newman, every character in The Last of Us Part 2 has this new mechanic including Ellie, her allies, enemies, the infected creatures and animals.
It works just as you expect it to work - when characters are performing strenuous actions like jumping, sprinting or engaging in melee combat, their heartbeat will increase just like in real life. This leads to heavier breathing and panting, which adds another layer to the game's stealth gameplay.
"I'm not sure if you noticed it, but as Ellie sprints around and then she settles, she’ll kind of [mimics heavy breathing] catch her breath," Newman explains. "What’s happening behind the scenes is that [Ellie] has a heart rate that is oscillating up and down. It goes up when you sprint, it goes up when you melee, it goes up when you take damage, and goes up into the presence of enemies. And that modulates the bucket of breathing sounds that she’s able to use."
As already mentioned, this same system applies to the enemies as well. For example, if their heart rate is too high, you can hear the opponents sneaking up on you and use that to your advantage, especially if they're already totally knackered.
"It’s been incredible because I found myself able to play cat and mouse with Clickers better than ever before because I can kind of understand them by the noises that they’re making," Newman explained his creepy playstyle.
