Battle Squadron is a classic arcade style shooter for 1 or 2 players. It's a spiritual successor to Hybris. You take a space ship and fly it over a high tech hostile surface, and then into an organic setting.
You can control the number of 'credits' you have from 1 to 3. You choose how many lives you get. You also get to choose the max number of enemy bullets and their speed.
You get power-ups along the way that modify your weapons, and also the "Nova Smart Bomb".
