THE GRID IS DARK. YOU ARE THE REPAIR CREW. Circuit Resistance turns foundational electronics into a tactile story-puzzle adventure. Unity AI has taken the grid offline. To bring the Resistance back, you must learn how real components behave, assemble working circuits, run diagnostics, and restore energy one sector at a time. BUILD TO UNDERSTAND Each mission begins with a field briefing and introduces the parts needed for the job. Place components into the correct sockets, study polarity and current flow, then run the circuit. Clear diagnostics explain what is missing or wrong, so every attempt teaches you something useful instead of ending at “incorrect.” A HANDS-ON ELECTRONICS FIELD GUIDE Learn batteries, switches, resistors, LEDs, relays, diodes, capacitors, coils, transistors, sensors, antennas, amplifiers, comparators, fuses, solar cells, potentiometers, regulators, supercapacitors, and more. Open the Component Glossary at any time for terminal diagrams, plain-language explanations, current-flow behavior, and interactive demonstrations. 49 STORY MISSIONS Begin with the Field Kit campaign, then continue through six optional expansion packs: • Power Foundry — generate, store, and regulate energy • Listening Post — turn light, heat, water, and sound into signals • Defense Grid — build alarms, latches, and wired logic • Iron Limb — control motion and protect motors • Comms & Signals — tune, detect, amplify, and transmit • Neural Core — construct analog decision-making circuits FREE-BUILD PLAYGROUND Step outside the campaign and experiment with every component in an open circuit playground. Reset, rearrange, and run your own combinations without risking mission progress. PROGRESSION WITH PURPOSE Complete missions to restore joules, raise your Resistance rank, and unlock achievements. Joules can also be spent on optional circuit hints when you need a hand. Progress is saved on your device. OPTIONAL GAME CENTER Submit restored energy to the leaderboard and earn an achievement for every completed mission. Game Center can be disabled at any time; local play and progression continue offline. DESIGNED FOR FOCUS • Cinematic story sequences with still-image fallbacks • Original music, responsive circuit effects, and separate audio controls • Haptic feedback and a Reduce Flashing Effects option • VoiceOver labels for core controls and circuit interactions • No ads and no account required • Includes a Resistance sticker pack for Messages The first Field Kit missions are included. Six expansion packs and Resistance All-Access are available as one-time, non-consumable purchases. Restore Purchases is available from both Settings and the expansion store. Learn the circuit. Rebuild the grid. Become the Resistance.
