Hi folks

I could use some advice for defence. I am playing Cassandra Classic, Difficulty: Adventure Story. Permadeath.
My colony (containing 12 colonists so far, 3 of them incapable of violence) was attacked by 58 manhunting guinea pigs.
I have 8 colonists in armour with heavy weapons (6x miniguns, 1x chain shotgun, 1x legendary sword). No chance!

How do you deal with something like that? Doomsday rocket launcher (I don't have one)?

I don't really know but i've seen some videos where they trap them in a room and burn them by overheating the room. Also cassandras raids always gets increased raids. Maybe you also have too much wealth.
Didn't have such a big raid before. But i didn't play the game that far yet

The only way I know to deal with large raids like that directly is a lot of traps.

Seriously, traps are your friend and they are stupid.

Those beasts also should have Scaria and after 3 to 5 days they will all die to Scaria. So if you have a wall around the entire base they will end up all dying.
