Thanks a lot for the detailed feedback!
Some of these ideas are actually very close to things we're thinking about, especially more varied enemy weapons, bunkers, mortars and expanding the tank/garage system.
Tank Breach has its own fictional universe, so we probably won't turn it into a strictly WWII or Vietnam game, but I really like the idea of giving some missions stronger identities: snow, desert, fortified areas, etc.
And 8-player Mega Drive Tank Breach with two adapters would be completely insane 😂
Thanks for taking the time to play and write all this!
