hey guys, so today i lost a game because i couldnt destroy the halley an enemy had. it would be nice if you could nuke/do other stuff to the halley while its moving whos with me?
You can. You just have to get there in time. Nukes, orbital lasers, shoot it out of the sky with an AnniLazor, bomb bots, bombers, built an anchor over it, you name it. You just have to do it before it smashes into you, which probably means you sent some guys there before it started moving. Now, if I recall correctly during the kickstarter there was some kind of probably-prerendered video where a bunch of nuke-looking missiles shot up at an asteroid as it came crashing down in an attempt to destroy it, so maybe you're talking about something like that? But I think that would ruin the whole point of cataclysmic destruction like planet smashing in the first place.
I've lost a round like this before too. Once that planet starts moving you can no longer order a nuke launcher to attack anything on the planet. You used to be able to do that and hope the missile made it in time.
