Punching tachyon guardians isn't exactly hard to do with most ships, and you could always quickly pause when the lab arrives if you needed to check before the lab gets shot at.
I like the idea but I have to agree with the others.
Yap. Me too. Bad idea at first, indeed.
The Science Deep Dive Lab gathers an additional 500 knowledge from an already tapped out planet.
Do you mean 500K more per human planet? On a 12 planets human empire (which is few in late game, I often end up with 15 or 20 human planets) it mean 6,000K, two planets worth, 40 AIP not increased. Let see what you proposed to balance it.
However, the AI reacts with moderately increasing exo waves and/or special forces in the area to stop you from revealing it's hidden secrets.
So the AI send special forces in deep fortified human territory. It doesn't seem balanced to me. It doesn't even seem a threat. Exo wave? Well, could be... but not for a global 6,000K or so.
I love the idea of digging K down too. (Heck, I even noted it as a possible reward for an expansion-lite I'm planning under the hood, but shhh)
Yeah, MkII Lab doing ARS scout is fine. I just wanted... I don't know, sort of easing the process. I feel like looking what's in an ARS should be as easy as scouting the planet. But MkII lab special scouting as it is now is fine; it spice things up without being big matter. Forget about it, I just needed to ear "your idea sucks" to realize it actually sucks. Sorry for that.
EDIT:
While I'm thinking about it: the hacker already do a "more K for no AIP", and its deal is pretty balanced.
