In Upgrade Complete, you have to upgrade everything! You have to buy everything in the game, from a menu to a shop and buttons. The game loans you $1000 to start, but you need to earn that back in the game to pay it back. To start, you have to buy a preloader, menu buttons, and a save system. When you are done buying things, you can click Back to Game to return to the game. When did you start the game, you can move your ship by pushing the left and right arrow keys. You need to shoot the oncoming attackers by pushing the space bar.
