DC34 CTF vs CodeBastion

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.

Build a city from its first camp into a lasting bastion in Code Bastion, a strategic idle clicker and incremental city-builder. Begin in Summary, where every tap matters. Gather wood, stone, food, and science through quick actions, manage your energy, watch your population, and keep your city moving even while you are away. Your resources continue to grow through citizen jobs and buildings, while seasons, incidents, and storage limits keep every plan under pressure. Move to Development to unlock a large skill tree across economy, construction, society, and expeditions. Each research choice opens new buildings, improves production, increases storage, strengthens manual gathering, expands your population, and prepares your city for the frontier. Turn a fragile settlement into a reliable system of farms, sawmills, quarries, mines, warehouses, markets, universities, barracks, walls, and more. Use the Resources screen to assign citizens to the jobs that matter most. Balance food, wood, stone, iron, coal, steel, gold, science, and influence. Build capacity before production overflows, keep enough workers in essential buildings, and adapt to changing seasons. Missions give every stage of the city a direction. Complete daily tasks, pursue a weekly campaign, and progress through a five-chapter city legacy: found the settlement, grow it into a city, open the frontier, endure its threats, and build a lasting legacy. When the city is ready, enter Expeditions. Train citizens, assign roles, craft preparation items, reveal a procedural map tile by tile, recruit from camps, discover points of interest, and research a catalogue of hidden treasures. Beyond the walls, every expedition can bring resources, experience, discoveries, and risks. Prepare for incursions with passive defenders and a timed defense challenge. Gather temporary materials, build defenses, create weapons, and decide how to hold the line when the frontier strikes back.
