Invaders - Games

Invaders represent a foundational game design archetype, typically featuring waves of hostile entities descending upon the player's territory. This mechanic creates tension through escalating difficulty and spatial pressure, often requiring precise timing and strategic positioning to survive. Symbolically, invaders embody external threats that must be systematically eliminated, reflecting themes of defense, resistance, and resource management. The concept has evolved from simple pixelated foes to complex AI-driven adversaries across genres, maintaining its core appeal through clear objectives and satisfying progression systems.
