Build tons of halleys in sandbox but couldn't figure out how to attack a planet. In the past it showed how many halleys you need next to the planet in the ui in top right but i don't see that now.
If oyu played on the randomly generated default system then the planets were too big to halley. You need to go into the system manager and create a planet with a radius 249 or smaller moon to be able to smash. Also visit Brianpurkisses (how to English, derp ) PA matches for useful tutorials, one of them being how to smash a planet.
