It's the year 1861. You are a soldier in the Civil War, and you have to defend against the enemy side, as your country is under attack. Press the X key to shoot at enemy soldiers. The different types of soldiers represent how different soldiers may have fought. How you progress in the game is by defeating all the soldiers in the wave. How you win is you have to beat all waves, and then you have won the war. (This game is not yet complete, so up to Wave 12 is done.)
I was not intending on people viewing this, this was just for a school project.
