Orbit Merge TD

Game Overview:
Orbit Merge TD is an innovative strategy tower defense game that seamlessly fuses minimalist grid-merging with orbital ring defense. Breaking away from the tedious construction of traditional TD games, players will forge high-tech weaponry in the central tactical zone while deploying devastating firepower on the outer orbit to crush endless waves of alien invaders.
Core Gameplay Mechanics:
【Grid Merging & Infinite Upgrades】
The 3 x 3 grid in the center of the screen is your ""Firepower Forge."" Consume energy to purchase base turrets, then drag and merge two turrets of the same level to upgrade them instantly. Level 1 + Level 1 = Level 2, Level 2 + Level 2 = Level 3... The higher the merge level, the more menacing the turret's appearance and the more cataclysmic its damage!
【Orbital Deployment & Crossfire】
Surrounding the grid is a loop-shaped defensive orbit where enemies march. Drag your high-tier turrets cooked up from the center grid onto the orbital slots. Once positioned, they will automatically lock onto and shred any intergalactic creeps entering their firing range.
【Strategic Unlocks & Tech Leap】
As you progress through stages, more locked orbital slots will become available. You will also unlock brand-new tactical turrets featuring freeze, splash, or high-frequency rapid-fire mechanics. Use resources earned from Giftboxes to upgrade your global Tech Tree, creating an impenetrable orbital fortress!
