    • Basics
      • This game has you defeat alien spacecraft one at a time using a combination of your own power and a computer allied forces player.
      • You can upgrade your shot power, the allied forces shot power, the strength of cannons, and the speed of the allied forces shots.
        • Your shot power translates into how many galactic coins you earn each time one of your shots hits the enemy.
        • The allied forces power translates into how many galactic coins you earn time one of their shots hit the enemy, and purchasing the speed upgrade makes their shots faster.
        • The cannon strength upgrade determines how much health is taken off the enemy when they are hit.
      • When you click on the enemy to shot, multiple shots are fired at once.
      • The allied forces only shoot a single shot a time, but shoot automatically even if you do not click.
    • Enemies
      • This game has 7 different enemies which you fight one at a time.
        • After you beat one enemy you unlock the next.
      • You start the first enemy with 0 Galactic Coins.
        • Each subsequent enemy starts off with more initial coins: 10,000, 100,000, 1,000,000, 100,000,000, 1,000,000,000, & 10,000,000,000.
    • Tips
      • When you first start fighting early enemies in the game it is usually best to use the cheapest upgrades available to get the most bang for your buck.
        • There is slippage in the upgrade price to where if the first item costs $150 the second item that is 15x stronger can cost $4,500, meaning the cost per upgrade unit is twice as high.
        • Later into the game when you start off with more coins at the beginning of your fights it can make sense to purchase some of the higher powered upgrades to start generating more income faster.
      • As you earn more money it will be hard to spend it all without purchasing more expensive upgrades.
        • Increasing earnings dictate you buy the higher power upgrades.
        • As your income grows you’ll unlock higher power options.
        • It makes sense to alternate between your power and allied forces as you power up.
      • Wait to upgrade the cannons until you are earning income at a great clip, as you won’t do much damage to the enemy until you are highly powered.
      • Be sure to quickly respond to the notification messages in the upper left to unlock free cash and boost your damage to the alien spaceship.
  • Target Audience
    • The game is suited for players who like idle clicker games.
    • The game has no adult themed content.
