Rimworld Zombie Apocalypse is a mod that adds Zombies to the sci-fi colony sim "Rimworld". Zombies are mindless killers who attack anyone, whether friend or foe. They have an infectious bite which is fatal to anyone unlucky enough to let themselves get bitten, and anyone who dies to a zombie bite will be reanimated as a zombie themselves and add to the ranks of the zombie hoard. If that doesn't sound bad enough, in the Zombie Apocalypse incident the zombie virus goes airborne, infecting everybody. Once the virus goes airborne all corpses, regardless of their cause of death, will eventually be reanimated as zombies. These things add up to make zombies an interesting and unique challenge to face in the Rimworld universe.

With this update the mod finally resembles the original image I had of it in my head way back in May. I now consider Zombie Apocalypse mostly feature-complete, and because of this I am calling the Alpha 7 release version 1.0. I will continue adding new features to the mod, but from this point on I will be expanding on my original vision of the mod instead of building up to it.

Rinworld Zombie Apocalypse [Alpha 7] (v. 1.0)

RimWorld Alpha 7

Tynan has gifted us with yet another impressive update to RimWorld. There are many more features in the new RimWorld update than I am going to cover here, so I'd recommend heading over to Tynan's blog post to watch his Alpha 7 release video and get the full list of new features.

The major features for this release include: melee weapons and melee combat related skills and traits; expansions to the medical system in the form of diseases, organ harvesting/transplants, amputations and prosthetic limbs; a new material system that allows you to make many things, such as walls, furniture and clothing, out of arbitrary materials (also known as the "Stuff" system). And of course this includes new kinds of materials like leather harvested from animals and new minerals that can be mined; a new trade system; and many, many more changes.

Zombie Apocalypse v 1.0

With the new Alpha 7 features I was finally able to implement a feature which I think we can all agree has been absent from the mod for far too long. I'm talking, of course, about Zombie Leather Cowboy Hats!

Zombie Leather Cowboy Hats are now a thing.

Thanks to the new Stuff system you can now skin animals and people for leather. That means your colonists will be able to hunt zombies while wearing their fallen zombie friends and family. And of course all clothing made out of zombies will have that nice familiar zombie-green color!

I'm sure Zombie Leather Cowboy Hats is more than enough to get you excited, but just to be thorough let's talk about the many less exciting features of the Zombie Apocalypse 1.0 release:

Melee Combat

With the addition of Melee weapons and Melee skills I really wanted to support and encourage Melee combat in Zombie Apocalypse. After all, while guns are extremely effective for crowd control if you have to take out many zombies at once, if you only have one or two to deal with the most efficient way is always just to knife them in the brain. But there is an obvious risk involved in letting your colonists get too close to zombies, so I have made some changes to give you ways of mitigating those risks a bit.

Now, if you're a zombie hunting pro who spends all day stabbing zombies repeatedly in the face, obviously you are going to be extremely skilled at making sure your favorite limbs and extremities don't get too close to the mouths of your victims. With the addition of the Melee skill the game now tracks your colonists' zombie-mouth avoidance abilities, which now reduces their chance of being bitten.

- The base chance of a pawn being bitten when struck by a zombie has been raised from 16% to 21%.
- Melee skill level now reduces the infection chance by 1% per level. So a colonist with a Melee skill of 0 will have the base 21% chance of being bitten and a colonist with a maxed Melee skill of 20 will have a 1% chance of being bitten.

Of course colonists with little or no Melee capabilities are going to be significantly more likely to be bitten, even than in previous versions of the mod. The base chance of being bitten has been raised to 21% for colonists with a Melee skill of 0, but a colonist with a maxed out Melee skill of 20 will only have a 1% chance of being bitten.

- Zombies no longer take reduced Melee damage.
- Cutting weapons now deal a base 200% damage to zombies, plus an extra 0-300% depending on Melee skill level.
- Cutting weapons now have a base 25% chance to one-shot Zombies, plus an extra 0-40% chance depending on Melee skill level.

On top of that, Melee weapons and attacks are now far more effective against zombies. I removed the 50% resistance to blunt damage mostly because now that damage type applies to more than just bare fists, but also because I felt that with the 50% resistance to certain types of melee damage the zombies could be just a bit too difficult to deal with when you accidentally let them get in close.

I also wanted to make things like Knives and Swords far more effective against zombies than anything else. All Cutting weapons, which includes Knives, Shivs and Swords, now get a base 200% damage bonus to zombies as well as extra damage based on Melee skill, and an extra chance at instantly killing them with a swift stab to the brain. The base chance of a kill shot with a cutting weapon is 25% for a colonist with a Melee skill of 0, and it goes up to 65% for a colonist with a maxed out Melee skill.

So hopefully these changes are enough to make Melee combat against zombies much more appealing than it used to be.

Zombie Infection

Zombie Infections now show up in the Health tab.

- There is now a "Zombie Infection" disease that infects the area of zombie bites. This disease will have various detrimental effects on a colonist's health, in addition to the usual damage that the infection deals. The Zombie Infection will be visible in the Health tab of any bitten colonist.
- The damage done to colonists by zombie infections has been slowed considerably to compensate for the added health debuffs.

I was able to take advantage of the new disease system to make zombie infections apply only to the part of the body that has been bitten. This means you can now see the zombie infection listed in the health tab. It also means that there are now certain health debuffs that your colonist will get from having the disease, depending on the severity of it.

And because of those debuffs I have decided to slow the damage that is done by the disease. Your colonists will live much longer after being bitten, but eventually they will no longer be able to function and they will slip into unconsciousness until they die.

- The red blink damage effect for bitten humans has been removed.

The blink was no longer needed since the zombie infection now shows in the health tab.

- Any bitten limb can now be amputated, curing the colonist of the infection, but leaving them with a permanent disability. This only applies to infections on limbs and parts that can be removed.

And of course with the new amputation system I had to add what is easily the most requested feature to date! If your colonist has been bitten on a limb or body part that they can live without, that part can now be amputated, saving them from the infection. It will leave them with a permanent disability, of course, but that is better than being dead. And you can always replace lost limbs with robot limbs later anyway.

Amputation of an infected limb removes the zombie infection.

Of course this only applies to certain limbs. Your colonists can still be bitten on the torso and head which will be fatal. But at least now you have a chance at being able to save your colonists, and I think that will make many people very, very happy.

Thanks for your support!

As always if you like the mod and appreciate all the work that has gone into it you can show your support by following, reviewing or rating the mod, or leaving some feedback in my thread on the Ludeon forums.

Not sure why, I wasn't getting any Zombie Raids so I decided to try and spawn one manually just to make sure it was working and turns out it wasn't. I got this Error, not sure what the problem is.

Make sure you create a new world after you start the mod, and then start a new game using the new world. That's most likely the problem you are having.

The game generates the factions when the world is created, so if you try and use an old world the hidden zombie faction that is needed to spawn zombies won't exist.

Oh, I know that. I generated a whole new whole world and new saves MULTIPLE times. Still can't get it to work, I can't spawn Zombie pawns either, I can spawn Zombie Leather & Meat though.

Some zombies will have a smaller range that they search for targets. This means for every wave of zombies a portion will stay behind until you kill them. If you don't deal with the zombie stragglers they can potentially turn a group of travelers into a zombie hoard when you aren't paying attention. This lessens the immediate threat of a zombie hoard, but makes them more threatening overall.

If you want to amputate a limb you need a bed that is set as a medical bed, some medicine, and a colonist with the "Doctoring" role. Then after you schedule the operation the colonist will need to lie in the medical bed before the doctor will perform the operation. You can select them and force them to lie down to get operated on.

The frequency of zombie raids depends on your difficulty setting, and there is some randomness to it. It could just be that you have a particularly long waiting period between your last zombie attack and the next. I can't really know what the problem is without having more information.
