Arcade-y artillery game where the sound effects are as impressive as they are massive and your character is a hero unit capable of feats like catching enemy artillery rounds and throwing them back at the enemy with a huge buff applied or personally reloading and firing a cannon to increase range and damage. Also things like possessing a round mid-air to personally guide it where it needs to go or ripping off a Bofors type cannon to fire in-person.
Windows on your screen show the devasting effects of your attacks up close to the enemy.

Primary challenge is destroying huge waves of enemies at long, medium and short range before they overrun and destroy your base. Tower defense like elements included.
