Rimworld Hardest Challenge

[James Talbot]

Pleasenote: This guide was made with version 1.0.2096 on Cassandra on Merciless difficulty - equivalent to Losing is Fun difficulty as of 1.1.2647. Gameplay changes after point may not be represented.

This guide details how to survive in the most hostile environment in RimWorld - sea ice. We focus on the Lost Tribe start because it's the hardest to thrive in in barren environments, since you have more people to feed and less technology to help you.

The tribal start in sea ice is the ultimate survival challenge in RimWorld and very close to being impossible, therefore there is not much room for different strategies here You have to stick closely to the guide.

The Sea Ice biome is one of the coldest biomes in the game. There is almost no animal life and no plants. In fact, you shouldn't expect to find anything more than three snowhares in your start. You also shouldn't expect to see more than one new snowhare every week.

In addition to that, there is no kind of soil available and moisture pumps will only generate more ice. It is literally impossible to grow anything in the ground.You will struggle a lot until you get a heater and a hydroponics basin, then you can plant something indoors.

Even worse is that there are no ruins, geothermal vents or minerals to mine. Also, deep drills don't provide rock chunks at all and won't even provide other resources without a ground penetrating scanner. There is literally nothing here to even build a base with. You'll have to rely on trading, quests and random events to get any material to build a base.

Even on the warmest sea ice tiles, it's still really cold. The average varies from -20 C (-4 F) to -30 C (-22 F) and they never have growing periods due to the temperature. You still need to eventually make a freezer though, because the summer temperature can be hot enough to spoil your food. Expect to have problems with hypothermia during fall, winter, spring and during cold snaps in summers.

They are particularly bad for travel by caravan. They do not have roads and are always placed in the poles of the world, so they have a big penalty to caravan speed due to winter, which is most of if not the whole year. But caravans are more important here than in any other biome, so you'll have to do it anyway whenever you can, because you don't have other reliable options to get the resources your colony needs.

In all maps you should choose your landing site carefully to increase the resources available. Landing in the wrong spot not only makes your start harder, but also makes your mid-late game frustrating, as it severely limits your use of the whole caravan and quest system. Sea ice is always in bad locations, but there is one thing that makes some areas better:

Go and visit your nearby friendly base to trade your merchandise colonists, your animals and some useless weapons. You should get somewhere between 1500 and 2000 silver for three colonists and three animals in addition to your starting 200 silver.

Now you have to buy some food, clothes and materials. Since you can't carry all the materials you need, you need to come back to trade many times. Food should be the cheapest option available. Nutrient paste meals, insect meat, human meat and vegetables are the best options. Meat is more expensive but it's better to cook that than buy fancy meals.

Clothes are just a little insulation to save you in the first season, the cheapest tuque is enough. After that, you need to either make your own clothes or strip clothes from raiders, even if they are tainted.

You need at least 25 steel to make your research bench and some wood to use for cooking. Try to build two research benches if you can, otherwise your other colonist will often be idle. Later, you will need more materials to actually build a base. First you want wood and steel because they are lighter, but later you want stone blocks, which are cheaper and do not catch fire.

It will more than triple your carry capacity and eventually give you wool. Unfortunately, there is no guarantee that a faction base will have a Muffalo for sale, unless you keep reloading before you trade until they have it. If you don't want to do this, you can keep three colonists with you and use two colonists for trading instead. But remember, a colonist eats more and carry less than a Muffalo, so it's going to slow down your progress.

Now the fun starts. You will harvest the organs, eat the meat and wear the skin of your enemies. If anyone tries to join your colony, you will sell or harvest them too because you can't currently afford more people. People who you will harvest include:

By butchering your enemies you will get food and leather, which you can make into tribalwears and sell, but that won't be enough. Everything you get is through trading, so you should also harvest and sell the organs of anyone you capture alive before eating them. It's worth buying medicine just for that. You don't need to do this every time, but it gets you a lot of money and will greatly speed up your colony building.

Make sure to buy some decent guns since your researcher colonist will likely have to defend themself alone while your other colonist is outside trading. Fortunately, you'll be so poor that even on the hardest difficulty, it's likely you'll only face raids of one single melee enemy for the whole first year.

Once your colonists have parkas and tuques you should take every opportunity available to go to another map. Your trading colonist should always be either trading or doing quests. Do not forget to take a bedroll with them on quests. Quests that matter now include:

You'll have more things to care about here than you normally would. It's important that you butcher every animal you find and every raider you kill on the quest locations. You might find your previous colonists (which you sold before) on those quests. If your human leather clothes and organs business is doing well, you can afford to bring one more person to your colony. Don't forget that you'll have to buy more meals for each person you save. Anyone you don't like can be sold or harvested once you return home.

Your research is really slow, since you only have one person at home taking care of everything and doing research at the same time. So another thing to focus on is furniture that you can carry home, since it will take a while for you to be able to make them. Heaters, batteries and turrets are also great to bring home. You don't have electricity yet, but once you do, you're going to have lots of things to plug in.

Make sure you have good clothes before winter starts. It's also about the right time to get rid of tainted clothes and make your own. Go buy cloth and make some decent parkas and tuques with it. Most importantly, make and sell lots of human leather dusters because they are worth a lot.

Time to make improvements. If you have at least two rooms and all the necessary workbenches, you can start replacing your walls with stone so raiders won't try to set them on fire Alternatively you can put a second layer over your walls made of stone. Replace your bedrolls with beds. If you want, you can also make some comfortable human leather armchairs and human leather animal beds.

You probably already learned to live from trading and quests by now, and may add another colonist. You should not expect to finish electricity before the end of the second year. So unfortunately, your food will spoil in the second summer. You can try to keep the stocks low to avoid loses or turn your food into pemmican.

Now however, you've got more people so you've got to set up some kind of defense, because raiders will be more numerous. This place is wide open, so you want to make an enclosed environment where you can shoot raiders from behind sandbags without getting outranged. In other words, you want a killbox. Once you finish electricity, you can finally use those turrets that you got from enemy outposts. If you could not bring any batterys home from quests, you'll have to research them now.

Your first priority after electricity is air conditioning, so you stop losing all your food in summer. Once you're done researching it, make a freezer. That will even allow you to accept more people in your colony since your food now lasts forever.

Then you want to make the almighty nutrient paste dispenser. It frees your cooker to do other stuff, completely prevents food poisoning and reduces your food consumption by 40%. You may even buy another Muffalo now to speed up trading.

You might have noticed by now that your worst enemy isn't the hunger or the raiders, but the mood penalties that come with harvesting and eating people. Still, you can't stop it, since without that you'd lose your main source of food and your two main sources of silver (human leather dusters and organs).

Now that you have a little extra silver, you can buy a solution: the Joywire. Overall, in such a stressful colony this implant is well worth it. The drawbacks of the Joywire can later be offset with bionics.

A greenhouse will require a lot of power, which means you will have to defend a larger area to put extra wind turbines in. You will also want to add a lot more batteries to store power at night so it may be used during the day. Make sure that your greenhouse is as small as possible to take less power, and is covered by double walls to increase insulation.

The greenhouse will allow you to stop buying food to survive and stop the cannibalism. Of course, it will also allow you to have more colonists. But first, you should plant some healroot so you can harvest organs without using good medicine. Also plant smokeleaf and psychoid plant, so you can make smokeleaf joints and psychite tea to reduce the overall stress in your colony. Then you may plant some food.

The scanner works normally on sea ice. If you set a colonist to work on it full-time, it can pick up locations of minerals faster than you can retrieve them. Which means you can endlessly make quests for minerals to greatly increase the amount of materials available for you to build your base.
