So here is a unique game that managed to find its way into my inbox. It’s actually an HTML5 Chrome web store game, but beyond even that it’s a unique PC-equivalent of the twin stick shooter that has you killing a multitude of monsters in an arena like setting.

Anybody who has played a game like Geometry Wars will be instantly familiar with the high concept of Onslaught! Arena. Essentially the game is just a twin stick shooter played on a PC. Except instead of using a left and right thumbstick, you’ll use WASD and the mouse. Not that that’s a bad thing as the control method actually works fairly well.

Aside from that everything else seems to be fairly standard affair for the genre. You’ll fight off waves of enemies, acquiring weapons as they drop with each successive wave being more and more challenging that the one that preceded it. It’s not entirely unique, but it sure is fun.

The game is available right now for $5, whch kind of seems like a steep price when Steam is practically giving games away. Still, if you’re looking for a fun browser-based game to play, I can’t argue against you checking out Onslaught! Arena, it even comes with a lengthy demo for you to play should you want to try before you buy.

Also, word to the wise, I would not play this game on Firefox. It was slow, sluggish and overwhelmingly a poor experience. I don’t believe this is the developers fault, but rather Firefox’s lack of strong HTML5 support. Google Chrome worked great.
