GunDeck[100] is a twin-stick shooter where the aim of the game is to conquer 100 levels of bullet hell.

Amass a ring of guns and blow off fireworks of elemental crystals that come in your choice of corrosive acid, freezing ice, eagle-eye homing, replicating magic, and sledge-hammer blight.

After each wave, choose from three dealt cards to add to your growing deck. But choose wisely! These cards will grant you new weapons, power up your shots, earn you companions, curse your enemies— or even curse you! (For a fair trade, of course…) Build yourself a powerful gun deck, or regret it when you meet…

…the ten big bad bosses that stand between you and the eponymous level. Not only do you get your pick of extra special cards for defeating them, you’ll earn yourself new ships with built-in features that change the way you play entirely. (One Gun Run, anyone?)
