Heartbeat.exe: Hidden Script

Chapter 1: Lag in the Limbs

The low hum of the cooling fans was the only sound in the room besides the rhythmic clicking of Ketsana’s mechanical keyboard. Blue light from three different monitors bathed his face in a ghostly pallor, highlighting the intensity in his eyes as the load screen for World-Zero finally flickered into the main hub.

"You in yet, man?" Bounthavy’s voice crackled through the headset, sounding like he was chewing on something crunchy.

"Loading assets now," Ketsana replied, leaning back until his chair groaned. "My ping is hovering at forty, so hopefully, no spikes today. I really need to secure this spot in the top hundred before the seasonal reset."

"Good luck with that. You seen the leaderboards? Someone named 'Null-Pointer' jumped ten ranks overnight. People are saying he’s either a god or using some crazy new scripts," Bounthavy said.

"I don't care if he's using black magic," Ketsana muttered, cracking his knuckles. "I just need to stay consistent. But first, priority one."

"What’s that? Strategic positioning?"

"No," Ketsana sighed, his stomach giving a loud, hollow growl. "I need my chips. I haven't eaten since noon, and if I don't get some salt in my system, my hands are gonna start shaking during the clutch moments."

"Fair enough. Grab 'em quick. The North Gate is already seeing some heavy traffic."

Ketsana reached out his right hand toward the crinkled bag of Jalapeño kettle-cooked chips sitting on the edge of his desk. His eyes remained fixed on the screen, watching his avatar—a sleek, armored phantom—stand idly in the town square.

He extended his fingers. But they didn't touch the bag.

Instead, his hand jerked back toward the mouse with the speed of a striking cobra.

"Wait, what?" Ketsana whispered, his brow furrowing.

"What's wrong? You drop 'em?" Bounthavy asked.

"No... my hand just... skipped," Ketsana said, trying to move his arm again. He focused entirely on the bag of chips, willing his arm to move right. Instead, his fingers hovered over the keyboard, twitching with a rhythmic, mechanical precision. "Uh, Bounthavy? I think I’m having a cramp. A really weird one."

"Just stretch it out, dude. Don't go getting a blood clot over a video game."

"It's not a cramp," Ketsana said, his voice rising in pitch. He tried to pull his left hand away from the WASD keys, but his palm felt like it was magnetically glued to the plastic. "Hey, I’m serious. I can't move my hands away from the interface."

"Quit messing around. We’ve got a queue popping in ten seconds."

"I’m not joking! My fingers are moving by themselves!"

On the screen, Ketsana’s character began to move. It wasn't the erratic, floating movement of a typical player. It was frame-perfect. His avatar turned toward the gate and began a series of complex maneuvers—dashing, jumping, and weapon-switching—in a sequence that would have taken Ketsana hours of practice to master.

"Whoa, chill out with the flashy stuff," Bounthavy laughed. "Save the stamina for the actual duel."

"I’m not doing that! I’m literally holding my breath right now and my hands are doing a frame-one cancel on their own!" Ketsana shouted, his eyes wide with genuine terror. "My keyboard feels like it’s vibrating. Bounthavy, I’m trying to hit 'Escape' to log out, but my pinky won't let me!"

"Dude, you're scaring me. Are you having a stroke or something?"

"I don't know! I can't look away from the screen!"

Suddenly, a system prompt flashed in red across the center of his monitor: FORCED CHALLENGE INITIATED: [ARCHON-LEVEL NPC] XAYAVONG ENTERS THE FRAY.

"Wait, Xayavong?" Bounthavy’s voice dropped. "The gatekeeper boss? Why is he spawning in the hub? That’s not supposed to happen."

"My character is drawing his blade!" Ketsana yelled. "I’m not clicking! My mouse is moving under my palm like it’s got a heartbeat!"

"Just hit the power button on the tower!" Bounthavy suggested frantically.

"I can't reach it! My arms are locked in position! It feels like... like my nerves are being hijacked!"

On the screen, the duel began. The NPC, Xayavong, lunged forward with a horizontal sweep that should have been unblockable. Ketsana’s avatar didn't just block it; he performed a perfect parry-counter into an aerial juggle. Ketsana watched his own fingers blur across the keys. He felt the cold plastic against his fingertips, the tactile click-clack of the switches, but he wasn't the one issuing the commands.

"Holy crap, Ketsana!" Bounthavy screamed into the mic. "I’m watching your stream feed! Nobody moves like that! You look like a robot!"

"I’m scared, Bounthavy! I want to stop!"

"You're winning though! Look at his health bar! You’re shredding a top-tier boss with basic attacks!"

"I don't care about the loot! I can't feel my wrists anymore!"

Ketsana stared at his hands. They were white-knuckled, working the controls with an icy, terrifying elegance. It was as if a ghost was wearing his skin like a glove. Every twitch of the cursor was aimed exactly at the NPC’s weak point.

"Okay, okay," Bounthavy panted. "Just ride it out. If the AI is playing for you, just let it finish the fight. Maybe the game glitched out?"

"I feel like I’m going to puke," Ketsana groaned. "It’s like... my brain is disconnected from my motor functions. I’m thinking 'move left,' and it goes right because right is the optimal dodge."

"You're almost there. One more hit!"

With a final, explosive animation, the NPC Xayavong shattered into digital pixels. A massive 'VICTORY' banner filled the screen, followed by items of legendary rarity cascading into Ketsana’s inventory. The second the boss fell, Ketsana’s hands finally snapped back into his lap, limp and heavy like lead weights.

"It... it stopped," Ketsana breathed, his chest heaving. "I have control back."

"That was the craziest thing I’ve ever seen," Bounthavy said, his voice full of awe. "You just cleared the hardest encounter in the game without breaking a sweat."

"I was sweating plenty, I promise you," Ketsana replied, rubbing his sore wrists. "I'm turning this off. I’m pulling the plug."

"Wait! Don't! Look at your chat log!"

Ketsana looked down at the corner of the screen. But the message wasn't in the global chat or his private DMs. A semi-transparent text box appeared directly in the center of his vision—not on the monitor, but seemingly burnt into his retinas.

[ SYSTEM: You're welcome, slow-poke. ]

Ketsana froze. "Bounthavy? Did you see that text box?"

"What text box? The one about the rewards?"

"No," Ketsana said, his voice barely a whisper. "It called me a slow-poke. Inside my head. I... I think it’s in the room with me."

"Bro, stop. You're giving me the creeps. Just go to bed."

"Yeah. Bed. Good call."

Ketsana pushed himself away from the desk, his legs feeling shaky. He stumbled toward the small bathroom adjacent to his bedroom, his mind racing. Was it a hallucination? Some kind of elaborate prank by a hacker? Or was he genuinely losing his mind?

He reached the bathroom and splashed cold water on his face. The chill helped ground him, at least for a moment. He looked up into the mirror, expecting to see his tired, pale face.

"Just a glitch," he told his reflection. "Too much caffeine. Too little sleep."

But as he stared at himself, his reflection didn't look back the way it usually did. He leaned closer, squinting in the dim amber light of the bathroom bulb.

Deep within his own dark eyes, he saw it.

Behind his normal pupils, a second set of smaller, circular apertures were glowing with a faint, neon electric-blue hue. They pulsed in sync with his heartbeat, expanding and contracting as if calibrating to the light of the room.

"Oh no," Ketsana whispered.

From the corners of his vision, the HUD elements he had seen in the game—his health bar, his inventory capacity—began to bleed back into his sight, hovering in the air between him and the mirror.

The dialogue box popped up again, floating right in front of his nose.

[ SYSTEM: Sync status: 88%. Ready for the next round? ]

Ketsana grabbed the sides of the sink, his knuckles turning white again. "Who are you?"

He expected a voice, but instead, his own right hand rose up against his will, pointing a single finger at the reflection in the mirror.

"No," Ketsana said, his breath hitching. "No way."

"Is something wrong in there?" Bounthavy’s voice echoed faintly from the headset still lying on the desk in the other room.

Ketsana couldn't answer. He watched his reflection smile—a sharp, calculating grin that didn't feel like his own. The pupils behind his eyes flared brighter, and he realized with a sinking dread that the chips he had wanted earlier were no longer the priority. Something else was hungry, and it was already seated at the table.
