The year was 2003, and for teenage Leo, the bedroom was a digital battlefield. The air smelled of dusty electronics and cooling fans. On the flickering monitor, the Global Liberation Army was mounting a sneak attack, and Leo was one well-placed "Particle Cannon" strike away from total victory.
Then, the world ended. Not with a bang, but with a system crash.
The Blue Screen of Death stared him down like a cold, digital tombstone. Leo sighed, reached for his PC tower, and performed the ritualistic hard reboot. He waited for the familiar whir of the disc drive to kick in, but as the desktop loaded and he double-clicked the golden Command & Conquer: Generals – Zero Hour icon, a dreaded dialogue box appeared:
"Please insert the correct CD-ROM, select OK and restart application."
"It’s in there," Leo muttered. He pressed the eject button. The tray slid out, smooth and empty.
He checked the second drive. Empty. He checked the jewel case on his desk. It held the manual, the registration code, and a scratched copy of the original Generals—but the Zero Hour expansion disc was gone.
The hunt began. He checked under the keyboard. He checked the floor, wading through a sea of PC Gamer magazines and empty soda cans. He even checked the freezer, because once, in a fit of sleep-deprived delirium, he’d put his TV remote there.
"Mom! Have you seen my game disc?" he yelled down the hallway.
"The shiny one?" her voice drifted back. "I saw it on the coffee table this morning. I thought it was a coaster, so I moved it to the media cabinet."
Leo sprinted to the living room. The media cabinet was a graveyard of VHS tapes and scratched Disney DVDs. He dug through The Lion King and Independence Day, his heart hammering. If the disc was scratched, his career as a five-star General was over.
Finally, wedged behind a copy of Titanic, he found it. No case. Just the silver disc, face down on the wood.
He picked it up with the reverence of an archaeologist handling a relic. He blew off a stray piece of lint, polished it against his shirt, and ran back to his room. He slid the tray shut. The drive spun up—a high-pitched whine that sounded like a jet engine taking off.
The screen went black. The EA Games logo roared to life. The iconic, distorted guitar riff of the soundtrack filled the room. "Constructing," the narrator's voice purred.
Leo cracked his knuckles, the blue light of the monitor reflecting in his eyes. The GLA wouldn't know what hit them.
