Start by naming any country that France borders. Then name any country that borders any of those countries. Then keep going until there are no more countries left to name.
Hi! This quiz is nearly flawless, but 1-x-x bomb shooter and 2-x-x bomb shooter should be switched around. Heavy bombs is actually after bigger bombs. :-)
I posted me getting 100% on r/btd6 and a lot of people in the comments went to try the quiz! I personally think this one is a lot better formatted than the one ISAB did, so I think it's deserved.
