ONE -- RAIDERS ACTUALLY DOING RAIDING
I always thought the purpose of the Raiders was to some raiding and steal our stuff, not kill us.
They should break into our base and steal our Food/Silver/Metal etc...
Like y'know.... raiders
Perhaps the purpose of the siege is to break your defenses, then they assault your colony and start thieving, OR they could have some sort of weapon/battering ram to attack your walls to get through faster.
TWO --COLONY LEADER
Have a specific Colony Leader, gives people around him a morale / skill boost (much needed in the current alpha), although they might take a morale hit if he dies.
THREE -- STEALTH
Special raider units, dressed in black, they come at night - maybe they have no name-plate so they are really hard to see?
Maybe they could be THIEVES or ASSASSINS - come to steal specific things, silver, AI core etc. or come to kill the Colony Leader
thoughts?
I like these ideas- similar to the "more mechanoids?" Post about the different "classes"
I like the ideal of a leader. Maybe choose how you leader rules, such as a slave-driver, militaristic, friend to all, corrupt. That was mostly negative types but I'd love to have a person all my colonist look up to.
