I play with Marvins "Sometimes Raids Go Wrong!" and sometimes they go wrong in a spectacular fashion, so spectacular infact - that they basically gave me a free colonist when i accepted "Suppy" who was running from tribals, if youre wondering what happened ; when Marvs mod rolls a 2 on a boarder attack raid, they can arrive under attack by manhunters, mechanoids or meteorites will drop on/around them - its sheer RNG, especially with the latter as the rocks may land too early to cause damage, manhunters and mechanoids can and will remain a problem for you, so its not entirely one-sided.
This particular time, the rocks landed so well that a good 75% or more of the raid was wiped out.
