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. Hostiles will pound your turrets to rubble — every tower has hull HP, every enemy has melee DPS. • Rocks blocking your line of fire? Tap them. Spend $50, clear the tile, reroute the enemy path. • 7 hostile archetypes: BASIC, FAST, TANK, FLIER, SHIELDED, HEALER, BOSS. Each has its own counter. CAMPAIGN • 10 sections × 20 waves = 200 levels. • 5 difficulties from Easy to Extreme — adjustable per run. • Persistent top-scores leaderboard tracks your best clears and wipes. NO FRICTION • No ads. • No in-app purchases. • No network required — plays anywhere. • No data collected, no analytics, no tracking. Built for one-handed portrait play. Boots in seconds, drops you straight into the build phase. Set a difficulty, tap ENGAGE HOSTILES, and defend.
