Seeing how Nelson is focusing on Unturned 3 again and plans to rework some core features like animals and vehicles, I’ve decided to compile some ideas I have for Unturned here, hope y’all don’t mind!
Disclaimer: I know game development takes a lot of time and effort, so I understand that many of these suggestions might not make it in future updates. I still hope they can happen one day however, and that’s why I’m making this post 
Animals/Zombies
Nelson has mentioned he’d like to merge animals and zombies into one base enemy type, so I’ll try to make my suggestions be for a “Base enemy” that can then become an animal or zombie type.
- Idle sounds
At the moment animals only make sounds when attacking you, or when running away, staying completely silent when doing neither of those. Zombies however do have idle sounds! If the merge does happen, I hope it gives us the ability to change idle sounds n stuff.
- Armed/Ranged enemies
Basically an enemy that doesn’t try to melee you, but keeps their distance and tries to kill you with a weapon/ranged attack. Think skeletons or ghasts from Minecraft, or I.O. guards in Fortnite:
AFAIK the closest we can get to this at the moment are acid zombies or reskinned sentries.
- Counter-Attack AI type
Currently animals have only three AI types: Defense (runs away when startled or attacked), Offense (attacks players on sight), or Ignore (ignores the player, runs away when startled or attacked). Would be nice if there was an AI type that would try to defend itself if attacked by the player.
- Sea/Air animals
RT if you also thought the Hawaii update was gonna add sharks 
ok but for real, I think it’s possible to make them work:
Sea animals: I can only think of making them detect when they’re in a water volume or in land to make the swimming work, and when on land they’d start losing health while trying to go back on water. As for AI, they would act pretty much like the current animal AI, except instead of running away they swim away. Think the fish in Minecraft for example.
Air animals: Can probably work like Phantoms in Minecraft or crows in Fortnite: they spawn in random intervals in the sky, they attack you (if hostile) or land on something, then fly away after a couple of seconds and despawn (if neutral/defensive).
- More mega zombie attacks?
This one is more of a “I’d like to see this, but it doesn’t have to happen” suggestion, but I’ll still write it down.
I only have one idea for the existing megas:
Groundpounder: Give it an attack where it locks into the player’s direction and rushes at them, stopping after a few meters or after it hits something.
As far as I know Flankers and Acid zombies are the only types of special zombies without a mega counterpart, so I thought of possible attack behaviours for them if they were to happen:
Flanker: Creates up to two fake clones of itself that have less health, but still deal the same amount of damage, and disappear when the real zombie dies. Could also have an attack where it disappears briefly, then teleports behind the player (nothin personnel, kid).
Acid: Attack #1 could be essentially just a reskin of the Flamethrower attack, except it leaves a trail of acid as a result. Attack #2 could just be the basic spit attack but it makes a bigger acid puddle idk
Also fun fact: When making Rio we wanted to have a special mega zombie that spawned red eyed zombies as an attack, but that didn’t happen and it got scrapped; Here’s concept art made by L2 way back in 2018:
I think that’s all I have for enemies. On to…
Vehicles!!
- Vehicle boosting:
Stealing this one from F-Zero but also Fortnite: But basically just making it so on the press of a button, certain cars get a speed boost, at the cost of your vehicle’s gas… The % of gas used can be configured in the vehicle .dat.
- Floating/cars with no wheels:
Play F-Zero X
That’s it, that’s the suggestion. It’s probably already possible but idk
- Animal “vehicles:”
Acts pretty much the same as a normal animal, except it can be tamed and used as a vehicle you can use them to travel around the map! It uses energy instead of gas/batteries, and when it gets tired it goes into a “resting” stance where it regenerates some stamina before letting you ride it again (can be sped up by feeding it a “preferred food”). Will wander around the area when not in use, unless tied to something (i.e. a fence). You can also “boost” while riding them, but just like the vehicle boost idea, it’s at the cost of the animal’s energy.
I think that’s it for vehicles, time for…
Music!!
- Ambience music:
I did ask Nelson about this a while ago, but this was his response:
I decided to think about how it can be achieved, and I thought of some possibilities:
For ambient/atmospheric music that can play at any time, similarly to Minecraft’s, having a radius where the music volume is lowered/muted when players are nearby could work, as well as having the server disable map music by default. Music/sounds attributed to an object could also be configured in it’s .dats to be server muted and/or lowered when certain criterias are met. Probably can have an option to not be lowered in i.e. safezones.
- PvE combat/boss music:
“why do I hear boss music?”
So I’m gonna use Fortnite as an example again for two reasons: first, because it’s also a PvP game with PvE aspects, and second because it implements it well, IMO:
But explained in text: Basically, it could be possible for certain animals/zombies to have custom music play when you fight them. Notice how the music fades in and out based on the combat situation, and the boss’s music overrides the basic enemy music. And just like I proposed for the ambient music, it can be muted by the server and/or lowered when real players are around.
I think these are all of the suggestions I had in mind, at least for these three topics; I’ll probably come back with suggestions for other features (i.e. gamemodes, maps) in the future, but we’ll see. Do let me know if I got something wrong by the way!

…And play F-Zero GX
