i'm trying to figure out the difference between soloing a level and doing it w/ 4 players. seems like
money and heat stays the same
minerals solo player gets 1/4 as much (although not exactly because the solo can choose the large mineral)
materials solo player gets 4x as much
enemy hp - is it linear? i.e. 4 player enemies have exactly 4 times as much hp as solo enemies? in other games enemy hp scaled up faster (e.g. diablo 2, in an 8 person party the enemies had 10x the hp)
I don't think enemy hp is doubled for two players, usually it adds around one more strike (4 instead of 3) for me to kill something in t3 if i have a partner.
Also a team of four taking turns can open 4 energy gates for the same price as a solo player opening one.
