Challenge Name: You are my Special 0
Category: Special CTF: CyberSummit V4.0 CTF
Description: Yuji swapped Inumaki’s onigiri. Big mistake. Inumaki just stared, then pulled down his collar and rasped three commands: “YouTube. Old game. Search.” Then he zipped his collar back up and walked away. No explanation. No hints. Just a mission. Yuji spent hours scrolling—past midnight, past 3 AM, past the point of sanity. Thumbnails blurred. Titles made no sense. He chased dead ends, clicked grainy uploads, and fought the YouTube algorithm like it was a cursed spirit. Just before dawn, he found it. He sent the link with trembling hands. A second later, his door slid open. Inumaki stood there, holding a fresh tuna mayo onigiri. He looked at Yuji’s exhausted face, gave a small nod, and whispered: “…Salmon.” Yuji took the onigiri. “Worth it,” he yawned.

Can you retrieve the name of the old game?

Flag Format: CyberTrace{gameFirstName_gameLastName}


The Challenge
#

We’ve got a pixelated game image and need to figure out what old game it is. That’s it. The flag format is CyberTrace{gameFirstName_gameLastName}.


Solving It
#

First Look: What Are We Looking At?
#

You open the image and… it’s super pixelated. Classic retro vibes, but honestly hard to make out at first. The art style screams early 2000s gaming, definitely a shooter of some kind based on the character models and military aesthetic.

Zooming In
#

After staring at it for a bit and zooming in, a few things become clear:

  • Definitely military/soldier-themed
  • Character models with that early 2000s FPS look
  • The whole vibe is unmistakably Wolfenstein franchise

The “Aha!” Moment
#

Search for “Wolfenstein games” and you’ll quickly land on Wolfenstein Enemy Territory from 2003. That’s it. That’s the game. Everything clicks when you see it - the character models, the UI, the art style. Classic multiplayer FPS that was free-to-play.

Getting the Flag
#

The format wants it as CyberTrace{gameFirstName_gameLastName}, so:

CyberTrace{wolfenstein_enemyTerritory}

Done. Flag captured.
