Made an update:
A preset of the first mission was made. Models, tools, and cards for each faction were also grouped (models are grouped by class - Elder Predators together, Elite Predators together, Alien Warriors together, Stalkers together, Marines grouped by squads, and so on). A separate copy of the rule book has been added to each faction, as well as a personal copy of the player-aid. That is, it turns out that each corner of the table is grouped by a faction + a corner of a conditional "game master" with tiles, doors, shared tokens and the main rule book.
I hope it will be even more convenient this way. Have fun.
