Particle Wars Extreme
Your task in this cool retro shooting game is to destroy waves of pixelated enemies and take down the endboss. Defeating end level bosses will make you cry tears of happiness, and you will want to play with a friend in the co-op mode. Use the ARROW KEYS to move your ship. Hold SPACEBAR to fire. Destroy 4 of the same colored enemies in a row to get a power up. Good luck!
