DC34 CTF vs Vibe Tower Defense

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.

Defend your base against five waves of increasingly dangerous invaders in Vibe Tower Defense — a hand-tuned, elemental tower defense game built for real strategic depth. STRATEGIC TOWER BUILDING Place and upgrade four distinct tower types — Arrow, Cannon, Frost, and Arcane — each with its own strengths against different enemy types. Manage your coin economy across waves that only get harder, and adapt your build as new threats appear. FIVE BOSSES, FIVE DIFFERENT FIGHTS Every boss wave is a genuinely different challenge, not just a bigger health bar: a Brute that destroys towers outright, a Stone Titan that ground-slams your defenses, a Plague Queen that silences your towers instead, a flying Iron Warden that shields off incoming damage on a timer, and an Ooze Tyrant that splits into more (and smaller) copies of itself the more you damage it. A GROWING ABILITY LOADOUT Unlock powerful base abilities by beating each difficulty tier and by pushing deep into Endless mode — Teleport Ray, Typhoon, War Horn, Bulwark, Toxic Cloud, Shatter, and the capstone Meteor Storm. Equip your favorites into limited loadout slots and fire them manually at exactly the right moment. UPGRADE GEMS Earn permanent upgrade gems by conquering Endless mode's deepest boss waves, and spend them to reduce ability cooldowns or add extra Teleport Ray targets — a long-term progression system for players who want to keep pushing past their last run. FIVE DIFFICULTY TIERS, PLUS TRUE ENDLESS Climb from Easy through Insane, then take on Endless mode, where the board itself changes at wave 50 — paths widen, the danger compounds, and "Endless: Unbound" lets you jump straight back into that late-game challenge once you've earned it. GAME CENTER LEADERBOARDS Compete for the best wave reached and the most enemies killed in Endless mode, and track your progress with Game Center achievements. No ads. Just tower defense, tuned deep.
