Rimworld Tips

[Lerxst]

If you're not using or can't afford turrets, give your colonists plenty of cover to hide behind while shooting (place 1x1 walls, sandbags, or debris) also clear a nice open space in front of them so the enemy can't hide either.

Don't let your batteries get wet.

Power runs down conduits form power plants to the devices. Place switches on conduits to shut down everything connected to the other end of the conduit. Layout your power grid so you can compartmentalize areas and shut down unneeded areas with a flick of a switch.

Coolers work best when the area they are vented into (the hot side) is either to the outside or a very large, open area - the smaller the area they vent into, the less cool the other end gets.

Food will rot. Refrigerators extend the lifespan. Freezers will extend it indefinitely.

Specialized medical beds (research screen) increase the odds of effective treatment. Herbal meds (made from plants you grow) are needed to perform surgery.

Keep an eye on the "Needs" tab for the colonists and do what you can to take care of them before they break. Some effects don't give you an alert until all Hell breaks loose. Sleeping in the cold, observing a corpse and an ugly environment are tolerable until a psychic drone passes over and causes anarchy.

Clear rubble and slag from around your base so your colonists have a clear line of sight to raiders, but provide some cover for your colonists with guns to use.
