About Alpha TD

Alpha TD - about the game
THE SEARCH FOR A NEW HOME

Resources on Earth are exhausted. Humanity is preparing a generation ship, but they have nowhere to send it. You are the vanguard—a proto-sentient AI integrated into a deep-space probe. Your mission: traverse the void, survive the silence, and find a habitable planet for the remnants of mankind.

CLASSIC DEFENSE, COSMIC SCALE

Parsec TD combines classic tower defense strategy with atmospheric space exploration. You are not defending a static base; you are defending your ability to keep moving.

  • Build & Defend: Humans teleport modular blocks to your location, assembling a mining platform near distant stars. Plan your maze, place your turrets, and protect the Energy Core at all costs.

  • Matter Harvest: Every enemy you destroy provides the raw Matter needed to build more turrets. Aggressive defense fuels your expansion.

EXPLORE THE UNKNOWN

Defending the platform is only half the battle. You must gather Dark Energy from the core to power your engines and jump to the next sector.

  • Pilot the Probe: Take direct control of your probe in Exploration Mode. Burn Dark Energy to navigate star systems and scan planets.

  • The "Princess" is in Another System: Most star systems are dead ends—hostile, barren, or unstable. But every planet you discover, habitable or not, yields Development Points.

  • Evolve: Use your data to research advanced turret upgrades and unlock new AI abilities.

KEY FEATURES
  • Cycle of Survival:

    • Defend the platform

    • Mine Dark Energy

    • Jump to a new system

  • Resource Management: Balance your Matter for defense and your Dark Energy for travel. Running out of energy means stranded in the void.

  • Tech Tree: Scan planets to earn research data. Turn your exploration efforts into firepower.

  • The Lonely Voyage: Experience the "silence of space" as you search for the one true "New Earth" among countless false leads.
