## What is Protocell Defender?

Protocell Defender - Cellular Tower Defense

Zoom in to the microscopic scale and defend your cellular nucleus against waves of pathogens: bacteria, viruses, camouflaged prions, life-stealing parasites, and worse.

GAMEPLAY
• 12 unique maps, from simple gut paths to the 3-lane final stand
• 7 specialized towers: Spike Cell, Membrane Wall, Mitochondria, Lysosome, Ribosome, Flagellum, Antibody
• Each tower evolves on 2 distinct paths (Path A / Path B) with cross-path mutations
• 20 waves per game, boss every 4 waves
• 3 difficulty modes: Normal, Hard, Impossible

ENEMIES
16+ types with unique mechanics: regenerating armor, camouflage, death-split, tower disabling, life-stealing, damage-reduction auras.

STRATEGY
• Synergies between adjacent towers (Supercharged, Acid Trap, Hunter, Efficient)
• 4 targeting modes per tower: First, Closest, Strongest, Weakest
• Punishing ATP economy: every placement counts

IN-APP PURCHASES (optional)
• ATP Boost +50%, +5 Starting Lives, Quick Save, 5x Speed
• All toggleable in-game and disabled in Impossible mode to preserve the challenge

No ads. No pay-to-win. Just a demanding tower defense that respects your time.
