You are the first line of defense against an invasion of baddies that threaten your civilization's very existence. Armed with only your trusty laser and elemental weaponry, you must destroy as many enemies as you can before it's too late... Make no mistake, you will die on this mission as a member of the Vanguard. The question is how long will you last?

This game is a space shooter that allows the player to move along the x-axis freely. The player can fire lasers at oncoming enemies or choose to use cooldown-restricted elemental weaponry for advanced effects.

The purpose of the game is to survive as long as possible, while accruing the the highest score. There is no distinct win condition, only death and legacy.

Elemental Weapons

In addition to the standard, unlimited laser projectile, the player also has access to elemental weaponry that can only be used every 20 seconds. These weapons accrue no points when they destroy, or contribute to the destruction of, enemies. The purpose of these weapons is crowd control to buy you time to survive. The cooldown timer on the right-hand side of the HUD will let you know both progress of the global cooldown as well as the timed effect durations.

  • Earth

  • Water
    • Slows all enemies for 10 seconds.
  • Air
