Browser tank game

Hi does anyone know how was online mmo tank game called. You could choose light/medium/heavy tank, you could collect weapons on a map. There were maps with grass, on some sort of planet with purple grass, vulcan ground. That game looks very similar to the game called tank ball (you can see it on youtube)

But it was much better as you could shoot from the hill even from very long range. The website that the game was had few other very decent 3d games like fps or some flight simulator and I tried to find it on google but I couldn't find it for 1 hour now..
