DC34 CTF vs Impulse Arena

DC34 CTF is a capture-the-flag game built for DEF CON 34. Fourteen channels are dark. Your job is to light them up. Download before the con. The app locks until the convention opens. When the doors open at LVCC West Hall in Las Vegas on August 7, it unlocks and the game begins. FOURTEEN CHANNELS. ONE FINAL TARGET. Every channel is a different kind of puzzle. Some are cryptographic. Some are physical. Some require hardware your phone didn't know it would be using. No hints. No walkthrough. Figure it out. The challenges span XOR ciphers, steganography, DTMF tone analysis, radio direction finding, Bluetooth beacon hunting, geolocation, reverse image search, physical navigation, NFC, speech recognition, and more. Your phone's full sensor suite is in play — camera, microphone, GPS, accelerometer, compass, Bluetooth, NFC. PRIZES The first three players to complete all fourteen channels and claim the final flag receive physical prizes: gold, silver, and copper coins. Finishers four through thirteen get pins. Your rank is permanent — logged to the live leaderboard the moment you scan the hand. THE LEADERBOARD A live in-app finishers board tracks every player who completes the game, ranked by completion time. Watch it fill up in real time. THERE IS MORE The app has secrets that have nothing to do with the flags. Some people will find them. Most won't. REQUIREMENTS iOS 17 or later. Game Center must be enabled — the app authenticates silently at launch. Several challenges require network access, Bluetooth, NFC, location services, camera, and microphone. Grant permissions as the game asks for them or miss the challenges that need them. The app is locked until August 7, 2026 at 9:00 AM PT. Show up at DEF CON 34, LVCC West Hall, Las Vegas. You can play anywhere, but final flag unlocking prizes is only available in-person.

Welcome to Impulse Arena, a fast-paced arcade battle where every collision matters. Take control of a powerful combat drone, enter dynamic arenas, and use precision, timing, and momentum to push every rival beyond the boundary before they do the same to you. Each battle takes place inside a circular arena surrounded by a dangerous outer edge. Your mission is straightforward but highly challenging: remain inside the arena while forcing every opposing drone across the red boundary. Smooth touch controls allow you to guide your drone with precision, making every movement an opportunity to outmaneuver your opponents and gain the perfect position for a decisive impact. Every completed level introduces stronger enemies, larger battles, and new tactical situations. Early stages begin with a single rival, while later arenas fill with multiple upgraded opponents that require increasingly careful movement and smarter positioning. Powerful boss drones eventually appear, offering a completely different challenge thanks to their increased size and resistance. Victories reward coins based on the number of defeated opponents, allowing you to continuously improve your drone inside the Garage. Unlock increasingly powerful upgrades to strengthen your impact force and prepare for more demanding battles. Additional boosts provide even more tactical possibilities. Freeze slows nearby enemies, Lightning releases a powerful shockwave that pushes rivals away, and Destroy instantly removes standard opponents while delivering a massive impact against boss drones. Return to earlier arenas whenever you need additional coins to unlock new upgrades and continue building the ultimate combat machine. Every improvement brings you closer to conquering stronger enemies and completing all thirty unique stages. Featuring responsive controls, satisfying physics, colorful visual effects, and action-packed gameplay, Impulse Arena delivers an exciting experience that rewards skill, strategy, and persistence. Every arena presents a fresh challenge where a single well-timed collision can completely change the outcome of the battle. Enter the arena, upgrade your drone, master every collision, and prove that only one champion deserves to remain inside the ring.
