Orbital Defense Protocol is a fast, focused, portrait-mode tower defense for iPhone and iPad. Place turrets, set traps, call orbital strikes, and hold the line through 10 sections of escalating hostile waves. CORE LOOP • Drag turrets onto the grid during prep. Tap to upgrade, sell, or specialise. • 6 archetypes: Pulse, Railgun, Frost, Blast, Gatling, and Command. Each upgrades in three channels (Damage / Range / Rate) and forks into a permanent specialisation at tier 6. • 5 trap and ability cards: Spike Strip, Slow Goo, Knockback Plate, Orbital Strike, and Stasis Field. Drag to deploy. • Tap MONSTERS to see the next wave's hostile profile — HP, speed, armor, shield resist — and pick the right damage type. DESTRUCTIBLE BATTLEFIELD • Walling off the path is legal.
