Once upon a time I played some kind of space strategy on this site. I remember that there were 2 parts, and the name began with O. There were also two resources in the game: electricity and materials. The power plants looked like a spinning multi-level disk. In the first part there were 3 parts of 6 or 8 levels. And the second one had 100 levels. I also remember that in the first part, infected opponents appeared who, upon death, released units that could infect all your buildings, units, and so on.
Please help me remember the name.
