Explosive shmup RPG Gemini Strike brings bassy shooting to iOS on September 4th

Everything feels good in Gemini Strike. Best of all are the explosions, which sound like the torrential bass warbles heard in Michael Bay's Transformers films.

Played with a single finger, Gemini Strike seems to throb at your touch, like a machine kicking into action.

Other spaceships try to attack you in formations but are as good as debris. They're the red barrels in first-person shooters; they exist simply to blow up.

It gets even better when you pick up one of the single-use weapons. With a double tap you send out fiery spirals and purple lasers that you can barely control.

Until one of the darting asteroids hits you square on, or one of the elite ships gives you as good as you dish out, you feel invincible.

Your job is to clear the screen and you move on. You do, with panache and bravura.

Aside from shooting everything, Gemini Strike also lets you swap out and upgrade modules on your ship. The modules you find are procedurally generated, so it works a lot like the weapons systems in Borderlands.

It's a lite RPG element that's much appreciated in what is otherwise a straight-forward pew-pew (with added BANG) space shooter.

Nothing else matters in Gemini Strike. The satisfaction of shooting things in this game is the ruler.

It even excuses the scripted banter between characters that must have been yanked from a Saturday morning cartoon.

You'll be able to download Gemini Strike for iOS on September 4th. Yes, it's a free to play game with IAPs - you'll have to earn those modules or pay up for them.
