When Ethan Nicolas’ iShoot hit #1 on the App Store list, he quit his day job to further develop applications. That meant he was making about $21,000 a day from 10,000+ downloads after Apple’s cut. Although it has dropped to #6, the $2.99 artillery game seems to still be making the bucks. There can be up to 4 players at a time, either human or computer, to see who can be the last tank standing. There are 25 weapons, including a mega mortar, dirt ball, stinger missiles and planet buster, realistic sound effects and authentic landscapes for destroying the planet, piece by piece.
