Of course, this is only useful advice for ranged colonists, but still keep your melee users in cover until they’re needed. Cover can be trees, walls, mountain and stone chunks, though walls and mountains are best. If you have plenty of cover around that area, position some colonists behind it in the direction of the attack. Raiders’ tactics vary, but to begin with they usually head straight for your base.
No mountains or walls nearby? Trees and stone chunks still make effective cover. How many arrive is based upon your colony’s points - a cumulative score of skills, numbers and items within your local map. Every now and then, people will come to steal your stuff (even if you only have a stick to share between your colonists) steal your people (even if they’re suffering from malaria) or just outright burn your base to the ground (even if it’s already on fire). The Rim isn’t a great place to set up shop.
What’s that you’re saying? We’re missing out something important? The cook’s got drunk and run off into the wilderness brandishing a rifle? Timmy’s stuck down the well? Welcome to the sixth of our RimWorld guide topics, which gets into the gritty business of combat and taking prisoners - if you want to.
