Ether Cannon - shooting game

Ether Cannon is a free online flash game of the category shooting games.

Defend earth from gaseous beasts! Rage your way through 21 levels of non-stop action! Be sure to stick around at the end for some cinematic goodies. Also, there’s an unlockable Hard Mode if you beat the game. I finished it, so YES, it is possible!

WASD or ARROWS to move. MOUSE to aim and shoot. M will mute the sounds, but you’re crazy if you do. (Yeah, I’m a DnB fan...)

A context menu should be shown when right-clicking or, on touch devices, long-pressing in the game. This menu especially allows to play in full screen and control the volume.
