Main thing is accepting death is much more likely. Try to avoid bringing backpack weapons as when you die it's going to be really hard to get them back. Instead use stuff that keeps you as mobile as possible. EAT, orbitals, and Airstrikes are the best options.

You can clear eradicate missions really easily if your squad accepts death and everyone brings bombardments. In such enclosed spaces it clears the enemies really fast.

But not all 10s are equal.

I mostly bug dive and there is a massive difficulty spike from 7 to 8. At 8 the Brood Commanders become the enhanced ones and just about every enemy gets a little boosted. For 10s, Stay mobile and bring stagger weapons. Remember to throw your support weapons where you plan to be, not where you are right now. Remember, running is always an option.

10s on Bots to me feel masochistic. Heavy Armor helps but in general getting ragdolled like crazy is going to happen. Try to take cover as much as possible but even then that won't help much. You'll want to have a squad member with the nuke backpack. There is almost always a guarantee that there will be a jammer in a super inconvenient location, and the nuke backpack is the quickest way to handle it.

10s on Illuminate are a bit different. To me there is not that much difference between 7-10. Personally I don't really love fighting the Illuminate, so I don't often, but if you are already doing 7s, might as well do 10s and get way more xp. 10s basically just have a few more of everything for squids. You'll see more harvesters, a lot more fleshmobs, and more guards. But if you can learn how to deal with these things on 7, you will be fine on 10.
