About Astral Guardian
Astral Guardian is a tower-defense game set in the year 3200, where humans on Noahstar fight invading monsters with towers combining high technology and magic. You build, upgrade and delete towers that fire weapons and spells such as rockets and magic lightning, while upgrading your own skills to face increasingly powerful enemies.
The human struggle
People on Noahstar take on different roles: some manufacture towers, research magic or manage resources, while others fight. They work together to improve the towers’ abilities and efficiency. After years of battle, humans defeat the invading monsters and recognize that protecting the planet’s ecological balance is the ongoing challenge.
Waves and victory
In wave-based play, monsters appear within a specified time. The game is lost if your castle’s life reaches 0; you win if the maximum number of waves is completed while your castle still has life remaining.
Multiplayer modes
The game supports LAN connections, cooperative multiplayer and battles. In battle mode, the player whose castle’s life reaches 0 loses, and the other player wins.
