it seems to have worked. except for the select all part.
"/c game.map_settings.pollution.aeging = 0.5"
and
"/c game.map_settings.unit_group.max_unit_group_size = 30"
made the game respond, i just don't know how to do the select all part if thats important.

I want to change the "Absorption modifier" from 100% to 50% and if possible the "Maximum group size" for the enemies to 30 midgame using the console.
Is that possible and what would be the commands to do that?
