ExtraPlanets is pretty much just a grind, not sure what kind of tips you are looking for. The most obnoxious part is probably getting the shield generator from Venus - the corrosive atmosphere destroys your space suits so fast you really gotta rely on other mods to figure out some way to survive. Once you get past that hurdle it’s really just the same loop: mine hundreds of each planet specific ore, make one million heavy duty plates, upgrade your space suit and thermals whenever possible. Repeat till you die of boredom or get to Kepler. One thing I will say is that the Extra Planets experience is made a lot less unpleasant when you have a ton of other mods to streamline things lol Answer from the_kedart on reddit.com
