First of all sorry if this topic was created before but i was unable to find something similar.
I found that different missions are scored in very different way. Some of them use same score value with some modifiers, some without and some are hardcoded. It wasn't easy to collect this information and few items were quite surprising.
Is this a temporary / target solution from technical point of view and from gameplay point of view ??
last UFO infiltration mission = sign alien pact for 150 points + build new base
last UFO alien base mission = build new base = mission score
ignore terror mission = 100 * mission score
terror UFO lands = starts terror mission = mission score
any UFO landed = 2 point per 30 minutes
any UFO flying = 1 point per 30 minutes
any UFO other then alien base lift the ground = mission score
each day of existing alien base = mission score / 10
