Searching for a specific space game

[Kungfujoe1110]

A few years back, I played an online flash or shockwave game, and I can't remember what it was called. This is what I remember:
It felt like asteroids; you were a ship that spun around and shot using the spacebar
It was Multiplayer, but you didn't shoot directly at each other. Each person was in a grid that had a wormhole or vortex in it or whatever.
As you picked up powerups, you'd shoot into the wormhole, and a big badguy would spawn in one of the enemies grids, and they had to try to destroy them. Enemies would do the same to you.

I think that's everything. Please please please please help me find it. In the words of Mr. Pink, "I'm completely...tortured."

Thank you for the help
