The Radio Tower is one of the first real milestones in HumanitZ, the top-down open-world zombie survival sandbox from Yodubzz Studios. Repairing a tower peels back a huge chunk of the map, chains you toward the next tower, gives your party a respawn point, and switches on airdrops. This guide walks through exactly how to find your first tower, the four parts you need, how to perform the repair, and what each tower actually unlocks — based on the current 1.0 full-release build (HumanitZ left Early Access on February 6, 2026).
If you are running your own world for friends, the gameplay loop below is tightly coupled to a handful of server settings. We will point those out as we go and link to the deeper config guides so you can tune airdrops, loot, and difficulty to match your group.
What the Radio Tower Does in HumanitZ
Before you go chasing parts across the map, it helps to know why the tower matters. A repaired tower is not just a cosmetic objective — it is the backbone of map progression in HumanitZ. Each tower you bring back online delivers four verified benefits:
- Reveals a large radius of the map around the tower — safe zones, points of interest, and major loot locations become visible instead of fog.
- Unlocks the next tower’s radio frequency, pointing you toward the following tower. Towers are a chained progression: each one tells you where to go next.
- Acts as a party respawn point, which is especially valuable in co-op so your group can regroup near explored territory instead of starting over.
- Activates airdrops, the periodic supply crates governed by the
AirDropandAirDropIntervalserver settings.
One honest caveat: a dedicated fast-travel reward between towers is not confirmed by the sources we trust. Towers reveal the map and serve as respawn points, but the ability to teleport between them is unconfirmed — verify it in your own game before relying on it. The same goes for any trader integration tied to towers: unconfirmed. Treat the four rewards above as the reliable, repeatable payoff.
How to Find the First Radio Tower
Finding your first tower does not require wandering blind. When you start a new game, check your inventory for the Former Survivor Letter. Reading this letter marks a green circle on your map at the location of the first Radio Tower. That green circle is your destination — head toward it.
Because the surrounding map is still fogged at this stage, the trip there doubles as your first real scavenging run. Loot cars, houses, and shops along the way; you will need raw materials and the specific repair parts before the tower does anything useful. The tower itself is inert until you bring the four parts and interact with the electronics panel at its base.
Radio Tower Repair Parts
Each Radio Tower needs the same four components to be repaired. Three of them come from vehicles and automotive shops; the fourth has a specific source you should plan a detour for.
| Part | Qty | Where to find it |
|---|---|---|
| Car Battery | 1 | Abandoned cars and car shops |
| Electronics | 1 | Abandoned cars and car shops |
| Electrical Cable | 1 | Abandoned cars and car shops |
| Radio Receiver | 1 | A Music Store in a small town east of the first tower |
The Car Battery, Electronics, and Electrical Cable are the easy three — abandoned vehicles scattered across the world and any car shop you pass will turn them up if you search thoroughly. The Radio Receiver is the one that trips people up: it is found at a Music Store in a small town east of the first tower. Plan that detour into your route so you arrive at the tower with all four parts in hand rather than making a second trip.
If you are testing on your own server and want to skip the scavenging while you learn the mechanic, an admin can spawn items directly with the in-game chat command format /Spawn item_[Name]. We cover the full command system in our guide to running admin commands on your HumanitZ server.
Repairing the Tower
Once you have all four parts, travel to the green-circle location and approach the base of the tower. Look for the electronics panel at the tower’s base and interact with it. With the Car Battery, Electronics, Electrical Cable, and Radio Receiver in your inventory, the repair completes and the tower comes online — triggering the map reveal, the next frequency, the respawn point, and airdrops.
From there, the freshly unlocked frequency points you toward the next tower in the chain. Each subsequent tower needs the same four parts, so it pays to stockpile spares as you scavenge. The loop repeats: find the next tower via its frequency, gather parts, repair, reveal more map, unlock the next frequency.
Airdrops: The Server Settings Behind the Reward
The airdrop reward is the one tower benefit you can tune directly on a dedicated server. Two keys in your GameServerSettings.ini file control them. The file lives in the .\TSSGame subfolder of your server install, alongside a reference template named REF_GameServerSettings.ini, and you can edit it with any text editor.
; GameServerSettings.ini (World Settings)
AirDrop=1 ; enable airdrops
AirDropInterval= ; time between airdrops (set to taste)If airdrops are not appearing after you repair a tower, confirm AirDrop is enabled in the INI. A few related settings shape the experience around airdrops too — loot rarity per category (RarityFood, RarityRanged, RarityAmmo and so on, each on a 0–4 scarce-to-abundant scale) determines how rewarding the drops and the surrounding loot feel. For a full breakdown of these keys, see our HumanitZ server settings guide.
Using Towers Effectively in Co-op
In co-op (PvE) and PvP sessions, the party respawn point is where towers really shine. Once a tower is online, your group respawns near explored, revealed territory rather than at the edge of the fogged map. This changes how aggressively you can push into new areas: with a tower secured behind you, a death is a setback rather than a full reset to unfamiliar ground.
That makes towers a natural anchor for base building. Plan your fortified base — with room for workbenches, storage, and a garden — within the revealed radius of a repaired tower, and you get a defensible home next to your respawn and your airdrop coverage. Building behavior is tuned server-side by keys like BuildingHealth, Decay, Territory, and FreeBuild.
Tower-Adjacent Settings Worth Knowing
Several server settings interact with the tower loop. Here are the most relevant ones, all found in the World Settings section of GameServerSettings.ini:
| Key | Effect |
|---|---|
AirDrop | Enables airdrops (the tower reward) |
AirDropInterval | Time between airdrops |
RespawnTimer | Delay before respawning (tower acts as the respawn point) |
LootRespawn / LootRespawnTimer | Whether and how fast looted areas restock — affects part availability |
OnDeath | What you drop on death (0–3; exact top value is unconfirmed across sources) |
PermaDeath | Toggles permanent death, raising the stakes of every tower run |
Note that the OnDeath scale has a source conflict — the official wiki lists 0–3 while a host summary describes 0 = backpack/weapons, 1 = adds pockets, 2 = everything. The exact behavior of the highest value is unconfirmed, so verify it in-game on your build before relying on it for a hardcore run.

New to HumanitZ? Survival Basics Before the Tower Run
Reaching the first tower means surviving the trip, and HumanitZ does not hold your hand. You manage four core stats: Health, Hunger, Thirst, and Stamina. If Health hits zero you die; Hunger or Thirst hitting zero drains your Health. Strenuous actions — fighting, running, carrying heavy loads — accelerate the drain. Roughly half your hunger bar empties per in-game day, so plan to eat about twice daily.
For the journey to your first tower, a few tactics keep you alive:
- Fight one zombie (“Zeek”) at a time. Funnel them through doorways and terrain rather than taking on a group in the open.
- Kill Screamers first. Screamer zombies shriek when they spot you and pull a horde — drop them with a stealth headshot before they alert everything nearby.
- Manage noise and use stealth. Crouching and noise management are central mechanics; a quiet approach to the Music Store and tower beats a loud one.
- Pick the Starter Spawn. It is the easiest start, with a guaranteed drivable car, starter gear, and ample loot — ideal while you learn the route to the tower.

Frequently Asked Questions
How do I find the first Radio Tower in HumanitZ?
Read the Former Survivor Letter in your starting inventory. It marks a green circle on your map at the location of the first Radio Tower. Travel to that circle, gathering parts and loot along the way.
What parts do I need to repair a Radio Tower?
You need 1× Car Battery, 1× Electronics, 1× Electrical Cable, and 1× Radio Receiver. The first three come from abandoned cars and car shops; the Radio Receiver is found at a Music Store in a small town east of the first tower. Interact with the electronics panel at the tower base to repair it.
What do I get for repairing a Radio Tower?
Each repaired tower reveals a large radius of the map, unlocks the radio frequency pointing to the next tower (a chained progression), serves as a party respawn point, and activates airdrops controlled by the AirDrop and AirDropInterval server settings.
Can I fast-travel between Radio Towers?
This is not confirmed. Towers reliably reveal the map and act as respawn points, but a dedicated fast-travel reward between them is unconfirmed by our sources. Trader integration is also unconfirmed. Verify both in your own game before relying on them.
Why are airdrops not appearing after I repaired a tower?
On a dedicated server, check that AirDrop is enabled in GameServerSettings.ini (in the .\TSSGame folder) and that AirDropInterval is set to a reasonable value. Airdrops are tied to these settings, so if they are disabled, repairing the tower will not produce drops.
Do I need the same parts for every tower?
Yes. Every Radio Tower requires the same four components — Car Battery, Electronics, Electrical Cable, and Radio Receiver. Since towers chain together, it is worth stockpiling spare parts as you scavenge so you are ready to repair the next one as soon as its frequency is unlocked.
