## Description
_Upgrade Complete!_ is an action game which satirizes the trend of paid
upgrades in computer games. The game itself is a simple, vertically scrolling
shooter where your indestructible ship must go through 20 waves; completing
each wave requires destroying all enemies in your way. In between the waves,
the player can buy additional weapons and equipment for the ship and then
upgrade these elements, paying with virtual money earned by catching the coins
falling from destroyed enemies.
However, the upgrade system reaches further than that. For one, at the very
beginning, you have to pay to see the menu screen. Then you have to buy the
preloader and the menu buttons in order to begin the game proper. You can also
buy music, better graphics, the game logo, a background for the menus… There
is a simple achievement system. Of course, you have to pay for it, too.
