I’ve made a topic about this before, and it went on for a while, and by the end, the possibility still remained ambiguous/non-existent. However, I recently had an epiphany about how to add the general gimmick of a burrowing monster.
The idea of diving into the ground and moving about with part of the monster sticking out or whatever is out the window. The devs have stated it’s not a technical possibility because the game’s engine can’t handle it when the monster actually goes into and moves around in the ground. Hypothetically, you could give the monster what Behemoth has, and make it have a separate model for its traversal; but what happens on rooftops or bridges? What happens when the monster interacts with walls? It’s too many questions for such a thing to be added.
How, then, could a burrowing monster enter the game? Well, let’s look at a different type of traversal that could use a burrowing gimmick.
Let’s say that the monster dives into the ground, completely submerging itself; then reappears at another location. While the monster is actually moving, dust rises from the ground where its presence is meant to be suggested; this would probably be possible, since it would be similar to how Fissure’s visual effect works. The problem of the monster having to move in the ground is non-existent, since it just dives, disappears, then emerges again. If this still screw with the engine, then the monster doesn’t have to actually go in the ground. It could appear to nosedive, be surrounded by dust, and then vanish; its emergence would be a reverse of this process.
This traversal would differ from Goliath’s leap in a couple of ways. For one, it offers damage mitigation because the monster momentarily disappears. Depending on what would have to be determined by the devs in actually play-testing the thing, different interactions with walls could occur; i.e. if the monster emerges from a wall, it cannot turn around and climb it, instead jumping out. This could be annoying or impractical, though, so it could stand to not be a thing. One more distinction of this traversal is, should the monster be on a bridge or rooftop and use the traversal, it simply falls through the bridge/roof. Again, this could have problems for actual gameplay/balance, though.
So would this actually be feasible? I’d kinda like to hear from the devs on this.
