Behemoth V2 - Complete Rework by lKiseki · Pull Request #18481 · tgstation/TerraGov-Marine-Corps

lKiseki · 2025-11-28T01:41:24Z

About The Pull Request

Check out the design document here.

⠀
Completely reworks Behemoth from the ground up. Its role in a hive has been redesigned, and its abilities have been changed to better accommodate for what is intended and expected of it. Visual and sound effects have also been changed here and there in lieu of changes and additions. Lastly, this PR also refactors most of the coding related to this caste.

To do:

(OPTIONAL) Replace Earth Pillar's icon with a basketball for Silly Mode.
(OPTIONAL) Complete resprite of Behemoth (commissioned GregorMN for this).

Why It's Good For The Game

Behemoth has been in a weird spot ever since its introduction into the game. It tried to do various things at once, and it failed to compete with marines and most other castes. This PR aims to properly define its identity and reflect that in its kit, while also making it an attractive pick for our players.

Changelog

🆑 Lewdcifer
add: Behemoth has been COMPLETELY reworked from the ground up.
spellcheck: The changelog only offers a very brief overview, so if you're interested in specifics, refer to the pull request.
add: Added a new ability, Seize. Fast movement option that requires Earth Pillars to function.
add: Added a new ability, Geocrush. Heavy melee damage.
del: Rolling ability removed.
del: Seismic Fracture removed.
balance: Redesigned Earth Riser, as well as Earth Pillars, to be faster, resilient, and versatile, but more limited in access, damage, and range.
balance: You can now climb and jump over Earth Pillars.
balance: Landslide redesigned to be much faster in execution, similarly to its now deprecated Primordial variant, at the expense of damage and reach.
balance: Primal Wrath, the Behemoth's primordial ability, has been completely redesigned. Instead of upgrading all of your abilities, it will now restore all damage taken in a time window, while providing a few seconds of invulnerability, in exchange for a stacking temporary debuff.
balance: Allied xenos can no longer ride the Behemoth.
add: Added various statistic trackers for several Behemoth actions.
soundadd: Added a few new sounds for Earth Pillars, Landslide, and Geocrush.
sounddel: Removed unused sounds related to Behemoth.
imageadd: Added some new sprites for Earth Pillars, Landslide, and Geocrush. Also reorganized Behemoth's stuff.
imagedel: Removed unused sprites related to Behemoth.
fix: Squashed some bugs and fixed some glitches or unintended behavior related to Behemoth.
refactor: Refactored most, if not all, coding related to Behemoth.

I hope it's bigger defender 🥹🙏

First pass. Lots more but a whole bunch of this stuff is just repeated minor issues for you to sort out

Yeah, I do need sprites for Earth Pillar. I'll see if I can get those sometime soon.

some review on the updates

 /// Applies various effects to a selection of tiles in front of the user.
-/datum/action/ability/activable/xeno/landslide/proc/on_move(datum/source, atom/old_loc, movement_dir, forced, list/old_locs)
+/datum/action/ability/activable/xeno/landslide/proc/user_move(datum/source, atom/old_loc, movement_dir, forced, list/old_locs)


its not a big deal but I meant something like /on_owner_move() or something so its just very clear exactly what is happening here and why.
The action isn't moving, the proc isn't moving the user either, its doing something because the owner moved.

I've changed this and the pre move proc to owner_moved and owner_pre_move respectively.

this should be in the file with the other isx defines

Done in next commit.

I think hitting someone directly with a pillar should do some damage
Very weird to nail someone in the forehead with a huge ass boulder and all it does is knock them down (under the rock)
Landsliding into a vehicle allows you to slide under/pass it
Considering how fucking awkward it is to engage a vehicle sometimes especially with a telegraphed move like Landslide
imagine you are parallel (or become parallel) to the hull and it drives into you and you decide to ram into it with Landslide (and hopefully hop on)
or you slide underneath and you get pushed backwards (into a marine mob) uhhhhhhh uhhhhhhhhhhh uhhhhhh fuck that
Geocrush can't be used against vehicles, don't know about structures (though it'd make it more like warrior punch x2 so I have no idea if you want it to do that)
It's still 2025 here

UltraBigRat · 2026-01-04T17:10:10Z

Played it and this is a pretty awesome rework. My only real issue was how long the cooldown on getting a new rock is, but its a pretty fair balance decision still with how strong it is here.

Jackal-boop · 2026-01-08T20:03:22Z

As long as they can still eat rocks im happy

TiviPlus · 2026-04-17T08:30:13Z

I'll discuss this with Lumi to see what they think.

or you slide underneath and you get pushed backwards (into a marine mob) uhhhhhhh uhhhhhhhhhhh uhhhhhh fuck that

This is an issue with most forms of throws (such as Runner and Hunter's pounces, Defender's charge, and so on). The xeno will just go under the tank, which can result in awkward scenarios like these. I'll see what I can do to fix it for Behemoth, at least.

Geocrush can't be used against vehicles, don't know about structures (though it'd make it more like warrior punch x2 so I have no idea if you want it to do that)

More walance stuff, so I'll also discuss it with Lumi.

It's still 2025 here

not anymore it isn't >:)

List of changes since last test merge

Stat changes

Melee damage reduced from 28 to 26.
Armor penetration increased from 10 to 15.

Earth Riser

Hitting a target directly with a rock (as in, having it land on top of them) will now deal brute damage equal to the Behemoth's slash damage.

Earth Pillars

Reduced their armor against melee attacks and bullets.
- Before: 60 melee and 50 bullet.
- After: 40 melee and 40 bullet.
Health bar is now visible to everyone, not just xenos. Besides being good for clarity, it's also a way for me to compensate for the lack of damage representation on the icons, since I couldn't get those.

Geocrush

Increased the percentage of stamina damage dealt by this ability, from 50% of the Behemoth's slash damage to 100% of it.
This ability can now hit objects of all kinds (including vehicles like APCs and tanks), not just living mobs, dealing an amount of damage equal to the Behemoth's slash damage. Against objects specifically, this is multiplied by 4.

Bug fixes

Fixed a bug where an Earth Pillar's health bar wouldn't update in certain circumstances.
Fixed a bug where Geocrush could hit allied xenos.
Removed a leftover message for admins from debugging (hi Titan).

Code stuff

Moved isearthpillar to is_helpers.dm, together with other similar procs.
Added various new comments, and edited some existing ones, to better explain what I'm doing throughout the file.
Earth Pillars now use the climbing component instead of the var.
Removed some commented code regarding Earth Pillar icons. I couldn't get these, but the health bar being visible to everyone should make up for it until then.
Adjusted Geocrush's target acquisition, and relevant checks, to account for the changes specified above.
Adjusted button code to be compatible with Geocrush's intended functionality.

HI MAINTAINERS PLEASE TEST MERGE THIS DO NOT MERGE IT I MADE BIG CHANGES THAT NEED TESTING

Lumipharon

Most of this is OK at a quick review, but some of these geocrush interactions are pretty cursed.
