About This Game

The invasion comes from every direction.

You pilot a fighter locked to a circular arena. On the outer lane you fire inward at the swarm closing on the core. Drop to the inner lane and you fire outward, catching the crawlers climbing over the rim. Switching lanes at the right moment is the whole game.

TWO WAYS TO PLAY

ARCADE: A classic score-attack campaign. Fight through 4 sectors of 6 stages each, grab weapon letters and power-ups, and take down a colossal boss at the end of every sector. Chase high scores, and use a continue when it all goes wrong.

SURVIVAL: Stay alive for 10 minutes. Collect crystals to level up, pick 1 of 3 upgrade cards each time, and turn a single gun into a screen-filling storm. Max out a weapon, pair it with the right passive, and crack open an elite's supply cache to evolve it into something absurd.
