The game in question is fron around 2010. It was a strategy game around defeting a race of alien squids who want to exterminate humans while utilising ships, lasers, wormholes, gravity waves and gravity bombs. Wiyh gravity weapons you can shov planets and stars into each other or out of the habitable zone. As well as with wormholes. With ships and lasers you colonise and lower the pop og enemy planets. There are missions. I found this game 3 years ago but forgot its name again.
Any help is welcome it was a true classic
