Run Soldier Run is a side-scrolling game of survival. Missiles and balls drop on you and you have to avoid them and keep your soldiers alive.

You get more soldiers if you lose them, but you don’t want to lose them. For the most part keep your soldiers together, especially at the beginning. The balls always jump the same distance each bounce so use that to anticipate where the ball will land and make sure you don’t have a soldier there. This prediction becomes vital later in the game.
It’s not that hard, and it’s not that fun, but the soundtrack is great.
