Update:
RimWorld - Biotech is now available! Hey all - Tynan here. This is the first of our Biotech preview blog posts, where we lay out the features of the Biotech expansion, and the thought behind them, in more detail. You can look forward to more posts on the way. (If you missed the
Biotech announcement, you probably want to start there. You can
wishlist RimWorld - Biotech here.)
Today’s preview post covers mechanitor core concepts, mechanoid infrastructure, and labor mechanoids. The next post is in a few days, and will cover combat mechanoids, enemy super-mechanoids, and other mechanitor-related features, and there will be many more after that.
Check out the other blog posts:
The mechanitor
A mechlink is a new implant that allows a person to form a direct mental link to mechanoids and control them via electromagnetic signals and psychic influence. Someone who has a mechlink is called a
mechanitor.
Mechanoids aren’t controlled independently, but through a human - this design intentionally keeps the mechanoid systems focused on a human being, which is critical to building an emotional story.
Mechanoids can perform in both work and combat. Some mechanoids are workers that will politely harvest crops or haul items as long as their little power cells are charged. Some can work or fight, crushing rock and bone with equal ease. Finally, there are a wide array of pure combat mechanoids with very diverse abilities. Incendiary beam weapons, movable projectile shields, long-range charge lances, blade-covered scythers, flame-spitters and more can be deployed in many combinations to defeat any threat via interlocking tactics.
There are a few ways to become a mechanitor, and all involve looting technology from an ancient dead mechanitor. If you can dig a datacore out of an ancient ruined super-mechanoid, you can use it to call an ancient mechanitor’s ship to land at your colony and harvest the mechlink from his body. Alternatively, you might be able to learn about an ancient mechanitor’s command complex, go there, penetrate inside through the security systems and grab the mechlink from him. You can also start the game with the new mechanitor scenario, where you begin the game as a solitary mechanitor with a mechanoid buddy.
It’s possible to do a single-person mechanitor run, where one mad scientist type lives alone in a grand base surrounded by walking, semi-thinking machines. Making this possible was a design goal from day one, because exotic play paths are so fun to explore. However, we expect mechanitors to most often live more normally among other colonists, commanding mechanoids to work and fight alongside human allies. If you really want to scale up, it is possible to collect multiple mechlinks and turn several colonists into mechanitors, though this takes a long time.
All our game mechanics interact freely. It’s possible for your mechanitor to also be a high noble with the
Royalty expansion, a religious prophet with the
Ideology expansion, and a deathless blood-drinker with this
Biotech expansion, because why not?
Mechanitors start out with the ability to command just a few small mechs. Over time, they can grow a grand swarm. They do this by gaining more
bandwidth and
control groups:
-
Bandwidth determines how many mechs a mechanitor can gestate and control at once. A mechanitor who loses bandwidth will temporarily disconnect from some of their mechanoids. If a mech is left disconnected for too long, it may reconnect with the wild mech hive and leave - or attack.
-
Control groups are groups of mechs who can be controlled as a unit. A mechanitor with more control groups can send mechanoids to do more separate tasks at the same time. A more advanced mechanitor can have combat mechs patrolling a colony, labor mechs toiling in the field, and bodyguard mechs escorting them around, all at the same time.
Mechanoid challenges
A basic game design principle is to
push things as far as they can go without breaking the game - that means make tools more powerful, enemies more dangerous, changes more overwhelming than seems safe at first. The idea is to ensure you’re exploring the full range of experience that’s possible in your game systems.
So we wanted mechanoids to be very powerful in order to create more extreme situations and distinct playstyles. The more impact they have, the more they can transform your game. However, in order to not unbalance the game, this meant that they needed to come with serious challenges as well. But what?
Existing costs in the game are things like consuming food, chemfuel, or steel over time. But simply making mechanoids consume resources wouldn’t feel transformative, and wouldn’t substantially alter gameplay since the mechanoids can pay for themselves by producing the resources they consume. The collect/spend loop is too simple and has almost no side-effects on the world, story, or characters.
So we decided to emphasize two new challenges that would come with mechanoids: Infrastructure and pollution. We cover infrastructure below - A future post will cover pollution, its causes, consequences, aspects, uses, and solutions.
Mechanoid infrastructure
Mechanoids require heavy infrastructure that takes up a lot of space and burns a lot of electricity. Big sections of your colony can turn into mechanoid maintenance, production, and control centers. You’ll feel your plucky wooden village transforming into a grand integrated machine of generators, chargers, control nodes, and gestators. Your base will tend to grow large with a lot of mechanoids, and have a lot of things moving and consuming.
Each mechanoid must contain a mechanoid brain known as a
subcore (short for subpersona core - the psychic substrate on which a dim, sub-human-level intelligence can be hosted). There are several tiers of subcores, with more advanced mechanoids requiring more advanced subcores.
Basic-level subcores can be produced by a mechanitor with just some resources and time at the
subcore encoder.
More advanced subcores require scanning the psychic pattern from human minds. A person can be placed in a
subcore softscanner and scanned to produce a subcore. This causes temporary mental effects but is ultimately harmless.
The most advanced mechanoids need extremely high-fidelity psychic patterns to work, and these can only be readily produced using the
subcore ripscanner, which scans the brain quickly at ultra-high energy, destroying it in the process.
Once a subcore and resources are ready, mechanoids can be produced in
mech gestators. Instead of being built like normal machines, mechanoids are gestated in a mechanite-rich solution that accretes the mechanoid molecule-by-molecule in a quasi-biological process. Gestation takes time, electricity, resources, and occasional guidance by your mechanitor.
Only a mechanitor can guide the gestation process, since it requires a psychic link to the growing mechanoid. As always, everything about the mechanoids links back to the human whom they serve.
The gestator can also resurrect some types of mechanoids. This makes your mechanoids more expendable in combat, which makes using them in combat give more distinct strategies compared to using human fighters.
There are several sizes of gestators. Small gestators are used for smaller mechs, while larger gestators are needed to produce ultra-heavy war machines. Little mechs gestate quickly, while big bosses take a long time to grow.
Mechanoids consume their onboard energy supply over time and must recharge at
mech rechargers. Mechanoids will automatically seek out available rechargers so they don’t run out of energy. If they do run out of energy they’ll enter a self-shutdown state and recover energy very slowly - it’s much better to have a mech recharger available to keep your mechs working hard. There are several sizes of mech rechargers appropriate to different tiers of mechanoids. They consume a lot of electricity, and produce pollution as well - the characteristic cost of mechanoids.
Band nodes are signal amplifiers that can increase a mechanitors total bandwidth. They can be quickly tuned to a specific mechanitor. However, returning a band node to a different mechanitor is a complex task and requires a long time. There is no limit to how many band nodes a mechanitor can build, so a mechanitor can have a huge swarm, though it will require heavy infrastructure to control.
Mech boosters are enhancer buildings that boost the speed and work ability of mechanoids nearby. Great for powering up mechanoid-based factories.
Mech signallers are a set of single-use structures that can be used by a mechanitor to call in fearsome super-mechanoid enemies to attack you. You need to call these enemies so you can loot their corpses for special high-tech mechanoid chips. These chips are core to the mechanitor’s progression since they are needed to advance to the next tier of mechanoid technology. This structure of “choose your enemy and be ready” is a little bit new for RimWorld, and creates a new kind of self-directed game pace for the player (as opposed to being blindsided by raids at any time).
We’ll explore these super-mechanoids in more detail in the next blog post.
Labor mechs
Labor mechs can perform a variety of work tasks (but not absolutely everything - some things still need a human touch). Some are plucky little worker bois who are best kept away from danger, while others are hulking crusher machines that tank damage with ease.
Paramedic mechs are designed to aid in emergency situations. They can rescue the wounded, fight fires and even perform surgery. The paramedic has a built-in jump launcher for quickly getting into and out of emergency situations, making it excellent for extracting downed colonists from battle. It also has a built-in firefoam popper which it can use to extinguish fires. It also has basic medical skills - it can tend the wounded and sick, and even perform surgery when a skilled human isn’t available.
Lifters are there to move things where they need to go. They’re small, weak, pretty easy to get and always useful. They will haul a corpse to a grave or rearm a turret. They lack a real weapon.
Constructoids can perform an array of construction tasks, from building roofs to repairing buildings and even hauling resources to blueprints. The constructoid is equipped with a small slug gun for light defense and built-in cutting blades, but is not a good frontline fighter.
Agrihands are small mechanoids designed to sow and harvest crops and can perform a blunt melee attack.
Cleansweepers are light mechanoids that clean filth and do blunt melee attacks.
Fabricors will craft all manner of manufactured objects at your work benches (though they can’t do the same quality of work as a skilled human). Like the constructoid, the fabricor has a small slug gun.
Tunnelers are massive, heavily-armored mechs equipped with gigantic crusher claws. The tunneler can dig tunnels and mine resources tirelessly. In combat, it is slow but its very strong armor makes it an excellent tank for absorbing enemy fire while your other fighters deal damage. The tunneler has a small built-in smokepop pack which can activate to spread smoke and shield itself from incoming fire. It also has a shield pack that recharges over time. Its weakness is that each time it takes damage, it slows for a few seconds - this means that when tunnelers attack you, even if you can’t kill them quickly, you can intelligently kite them by falling back from your position to escape the blocking smoke, maintain distance and slowly whittle the tunnelers down. (More on mech combat in the next post.)
