Extinction does not have a large body of water. As you can imagine, the surface of the Earth has undergone some dramatic changes, one of which is that most of the water has dried up. That said, we did build the Extinction creatures with water in mind, and there should be a few surprises waiting for you when you take them to other maps!
We think that Cryopods coming in Extinction should help with this problem directly. When a creature has been captured into a Cryopod, it does not count against the tame cap of the server. In addition, Cryopods can be kept forever in a Cryofridge with power, arming players with a powerful tool to work around the limitations of the cap.
Our hope is that Titans bring a new type of PVE encounter to the game with in-world boss fights and interesting new mechanics that are interesting in themselves. Once tamed, Titans are very powerful. They can clear space and take down lots of dinos quickly making them good for area cleanup or meat runs. In addition, we’ve worked to make each of them fun to ride. I enjoy exploring the various maps on them for that reason.
The Defense Units found within Extinction are part of the automated force that served and defended the city before it fell into disarray. These days they like to roll around and punch Dodos. They aren’t craftable like the other Robots found within the city (such as the Scout or Enforcer), but we felt like they brought a missing piece to the ecosystem there, namely punching Dodos.
There are a number of creatures that make their return in Extinction, and they exist in biomes/environments that you’d expect to find them in. In addition, a number of existing creatures have been corrupted by Element and they roam the wasteland. These creatures will not behave as they would traditionally, instead destroying anything that gets in the way of their hunt for additional Element to consume.

Undermeshing refers to the ability to get to where you aren't supposed to by moving outside of the playable space. Almost every game is susceptible to undermeshing in some form. Most speed runs rely on undermeshing, for example. It's effectively impossible to solve completely, at least automatically. The approaches taken to prevent it are usually a tradeoff between how much freedom you want the player to have, how complex your world is, and how much processing time you can afford to spend on physics. Generally, when there's an instance of meshing, it's caused by bad collision setup, improper level geometry (holes), or a problem with the algorithm used to move the character through the world. In some instances, you place kill volumes in locations that you want to guarantee that the player doesn't end up, but that isn’t a global solution.
The collision setup for our objects varies based on their complexity. For very simple objects, we use a basic primitive shape (box, sphere, capsule) that matches the shape of the object. It's very good if you're able to take this approach, because natively the physics system can treat that individual object as water tight - ensuring that another physical object will never end up inside of it, and that you'll always detect it if you're already inside. When constructing a modern game, however, it's very likely that you need to use shapes that are more interesting to look at and interact with than a simple box or sphere - so you use mesh based collision. Mesh collision treats the surface of the mesh as the collideable surface, but it cannot be treated as watertight, and the physics system cannot guarantee that you don't pass through it. You might ask why, then, don't you try to represent that larger object as a bunch of smaller watertight ones? We do that in a small number of instances, but quantity of primitives is also a major concern, so it is not feasible to do this for the entire world. Take the ground under your feet, for example, at any given moment you'd be surrounded by thousands of primitives to approximate the surface of a natural looking ground, and yet it'd be less smooth than the pure mesh shape. In addition, a guarantee to not end up inside of a single body isn’t a guarantee that you won’t end up between them even if they’re tightly clumped, leading to more instances of getting stuck.
When we lay out our levels - we construct them in the way that is interesting and optimize them for efficiency so that we can maximize quality and quantity. What that means is generally the world outside of the space you're meant to play in is empty - we spend our resources on the spaces where players are at. In addition - we reuse assets many, many times - rotating a rock different ways to make it look different before shoving it into the terrain at various depths to mask the reuse and keep it visually pleasing. Technically, the physics for these objects overlaps, and if you get past the surface of one, you'll stand on the next one down. While that sounds like it would help, it’s actually the meat of the problem. Adding more meshes doesn’t help, because once you can get past one, you can get past the next one. That said, there have been many instances where we’ve flagged the collision on an object incorrectly, or left a minute hole that we can and do address through Level Design.
Nearly every game uses custom physics for characters. Much of ours is built on the out of the box simulation that you get from UE4. Fortunately for our players, our game is one where the world is vast and complex, and players have the freedom to build many objects and have many dinos. Unfortunately for us, this pushes all of these algorithms to their breaking point. We've had to augment, rework, and add additional tests in many places that affect the simulation to improve our core player experience. In addition, we've built many gameplay mechanics that don't exist out of the box. Wall climbing, for example, requires a completely new set of physics tests to understand and hug the wall surface. When we set these up, we build them to be as flexible as possible, but it can be difficult to predict how the player base will use something when they get it in their hands. In many cases, this is a good thing - we’re delighted with the creative things that our players do, but sometimes they’re able to abuse mechanics in unintended ways. When we find problems with them, we have to find solutions that won't break the mechanic completely for the many other use cases, sometimes an impossible feat! This is also why we aren’t quick to completely disable a feature - we evaluate how much harm versus good it is doing across the entire experience.
We do use kill volumes at a broad scale - usually high in the air, or far below the surface. Far outside of the playspace, to segment specific areas. The reality, though, is that when someone is meshing, they're usually not out in that empty space around the world, they're running around on the insides of overlapping shapes or physical surfaces that are just below the real surface. In order to implement kill boxes in these places, we'd have to go back to every location in the map and place a kill volume just below the surface that will kill someone that touches it. As with the terrain example above, it would require entirely too many objects to cover the entire world in these accurately. In addition, a major downside to this approach is also the fact that it will detect and kill something that may have a good reason to be below the mesh - on a Basilisk? You just got killed by the kill volumes. Misjudge where the surface is, and a bunch of players are being killed erroneously and losing their stuff.
As with all aspects of making a game, it's all a balancing act. We try to spend our time on the things that are most valuable to as many of our players as possible - which means attacking holes in the world in waves and making algorithm changes when it's become obvious that they're having a large enough negative effect on the experience for our players. The reality is that there is no silver bullet, no automatic solution - so it continues to be a problem that our game (and many others) continue to fight throughout their lifetimes. Recently, we’ve fixed a bunch of holes across all of the maps and did a pass at removing Climbing Pick exploits. Going forward, our best bet is to remain diligent about resolving issues as they arise and improving the experience over time. The good news is that we like solving hard problems - and exploits like these are some of the more interesting ones to try and tackle!

Hello Survivors! Today, I'd like to talk today about what goes into designing and building new gameplay mechanics. For brevity, I'll focus on the Scout, a creature that we've revealed as part of our upcoming Extinction expansion.
When we approach designing gameplay mechanics we start by brainstorming interesting ideas that would make a compelling addition to our sandbox. The Scout started as a desire for the ability to fly around the battlefield with a drone. We have several members of the team who enjoy flying drones, so collectively we fell in love with the idea of remote piloting early. We also had another gameplay mechanic that we were interested in that finds its origins in another franchise - the ability to tag enemies to reveal them to your allies. This idea was also high on our list, and through further brainstorming, we found it was a natural fit for the Scout, so they came together in the brainstorming phase.
From there we seek to match those abilities up with concepts that fit well into the world we're building. This one was pretty easy. We knew that we were building a futuristic city for Extinction, and immediately we latched onto the idea of some kind of automated security force that patrols it. It took several more sessions to land on the idea of the interplay between Scouts and Enforcers, and the way that the Scout is deployed, but we're happy with where it landed.
Next, we'll build the mechanic and iterate numerous times, using multiple weekly gameplay review sessions to nail the fine details. The Scout was deployable from a grenade and had remote viewing baked in pretty early on. Originally it's tagging mechanism was a projectile that it fired. This was very difficult to use, so we switched to more of a raygun. The tags originally lasted a very short time, so they weren't very useful. We've since upped the time that they last - making the Scout a key target for the other team to take out. In addition, we didn't originally allow the tagging of allies, but this slotted in naturally as a way to give a more complete view of the battlefield.
Finally, we turn our experienced set of player testers loose to hammer on the mechanics until they fit well. This process is underway for the Scout and for Extinction as a whole as I write this. We've got nearly all of the mechanics playable and we're iterating on the roles that they play individually and collectively within Extinction and within the larger game. As such, the abilities described above represent a snapshot of where they are as I'm writing this. These can and likely will change before launch! This is part of the reason that often times when we talk about something early on it doesn't match up with what the final product becomes. However this iteration process is necessary to deliver the best playing experience that we can.
Thanks for reading, survivors!
Fliers are allowed on Extinction! There will be a number of existing fliers that spawn in Extinction, and we’re working on a few more to add to your collection. That said, there will be new challenges for fliers on this map that we’re excited for you to discover and contend with.
While imperfect, a lot of thought and work went into building the kibble tree as it stands now. A number of us internally would like to make major changes to this, potentially rebuilding it from the ground up. The reality is that this represents a significant undertaking, and would be very disruptive to the game. If we decide to tackle this, it will be post Extinction.
We’re still hammering out the exact summoning mechanics, but the Titan battles in Extinction will take place on the live map. There will not be separate boss fight arenas for them.
S+ is a shining example of the benefits of releasing mod tools to the community. It contains a number of improvements to the building system that we’d like to integrate. That said, it also contains a number of features and mechanics that circumvent systems in the game. Given this, we aren’t planning to integrate the mod wholesale. We are, however, examining and tracking individual improvements that would make sense to integrate. Any improvements in this area would come after Extinction launches.
When we set out to build an expansion, we seek to add gameplay that adds to the core experience. Our goal, then, is to allow those mechanics to be used in all the places that make sense. Cliff Platforms work on all maps, for example. A number of the features we’re adding in Extinction are meant to be used across all of the other maps. They’re meant to change things up on multiple levels.
Unfortunately, no. When we set out earlier this year to rebuild the event system in a way that they would persist, we decided not to ensure compatibility between them. Largely they modify many of the same bits, so making them fully compatible would take a significant amount of work and lower the likelihood that we could implement cool things like the bone pile spawning in the ARKaeology event.
A number of our previous creatures will inhabit the Extinction map. As with our other expansions, we’ll bring across the ones that make the most sense and incorporate them. In addition, we’re adding the highly aggressive corrupted versions of a number of creatures to provide new challenges.
We like creating new and interesting events for our players. Unfortunately, most of our effort at that time will be focused on ensuring a smooth and enjoyable launch for Extinction. Doing a Halloween event and wrapping the expansion at the same time would have a negative impact on both, so we’ll be skipping Halloween this year.
We’re aware that our console players would like to see more in this space. We don’t have anything specific to announce at the moment, but stay tuned.
Prodigious, challenging, fresh. The Titans bring a number of new elements to the core experience through public boss fights and taming of even larger creatures. The new in-world event system we’re building will bring new gameplay to both PVE and PVP servers. Finally, the introduction of the city brings a whole new dynamic to exploration and building. I’m really excited about these new elements.
