>How would a 40K total war work?
Solar System map where you land on the planets for battles and planets and moons also count as your bases and "cities"
>How are the battles supposed to be in that setting
For the top tiers, it's a mix of Napoleon era warfare where thousands upon thousands of men fight in land formation, except everyone is faster than a bullet and they whip out their anime tier swords that can cut through armor when they run out of bullets.
There are gigantic skyscraper sized mecha and demons that prowl the battlefield until they get taken out by the top tiers of the setting.
For fodder tier soldiers though like normal humans, it would be more like trench warfare where soldiers stay huddled together too scared to march forward because they'll be instagibbed the moment they poke their head out of their trench.
The scale should be massive because there's quadrillions of every race and millions of people are dying everyday in battle. There are also unironically battles where hundreds of thousands of soldiers are deployed on both sides.
Oh, and there's lightspeed travel, but no one can spam it because going into lightspeed puts you in a dimension where demons can gangrape you to death if you're not properly prepared. As a result, travel between planets is slow, and logistics are a big fucking deal.
