Once Human Horizontal Portal

Once Human Horizontal Portal: Introduction 

The Once Human Horizontal Portal Guide kicks off with one of the sleekest tools in your base-building arsenal: instant travel. The Horizontal Portal isn’t just a cool sci-fi gimmick—it’s a game-changing facility that lets you zip across your base with zero fuss. If you’ve ever had to sprint across half your camp just to smelt some ore or grab cooked meat before it spoils, this little structure is your new best friend. Portals eliminate wasted steps and speed up everything from crafting to combat prep. 

In Once Human, your base is more than just a shelter—it’s a personal outpost, workshop, farm, and sometimes even a shopping mall. As it grows, so does the time it takes to move from one end to the other. That’s where the Once Human Horizontal Portal Guide becomes vital. With this system, you can split your base into zones—one for crafting, one for storage, one for defense—and connect them instantly with portals. Horizontal Portals do the heavy lifting, moving you across your land like a magic shortcut, no running shoes required. 

It’s worth noting that you can only have one active set of portals at a time—either Standing or Horizontal. So plan smart. Standing Portals work well for multi-level setups, but Horizontal Portals shine in wide, sprawling layouts. The Once Human Horizontal Portal Guide helps you figure out which setup suits your playstyle and base layout. Whether you’re running a minimalist outpost or a sprawling fortress with more rooms than a hotel, choosing the right portal system can save you time, frustration, and—if we’re being honest—a whole lot of running around. 

Portal Type	Best For	Key Benefit	Limitations
Horizontal Portal	Wide, spread-out bases	Fast side-to-side movement	Can’t be used with Standing Portals
Standing Portal	Multi-level, vertical structures	Quick up/down travel	Mutually exclusive with Horizontal Portals

Once Human Horizontal Portal: Ability to Craft Portals 

To craft a Horizontal Portal, you’ll first need to bond with a very specific entity: the Strange Door Deviant. This isn’t your run-of-the-mill loot drop—it’s a Crafting Deviant that unlocks the formula required to build portals in your base. Think of it like adopting a weird alien roommate who hands you blueprints in exchange for a little puzzle-solving and travel. In short, no Strange Door Deviant, no portal. And if you’re serious about fast travel, the Once Human Horizontal Portal Guide says this is your golden ticket. 

The Strange Door Deviant typically spawns near Lighted Doors puzzles out in the wild. These puzzles aren’t especially difficult, but the spawn itself is random, so expect a bit of legwork—or portal-less fast walking. While it’s not labeled as ultra-rare, you might need to check a location more than once. The Once Human Horizontal Portal Guide recommends persistence over panic. Bring snacks. Maybe a lawn chair. Keep revisiting until the Deviant appears and hands you the key to crafting teleportation like some interdimensional game show host. 

Location Description	Coordinates	Region
East of Throughville	(6504, -5225)	Dayton Wetlands
East of Gaia Research Center Ruins	(4377, -6465)	Broken Delta
South of Ricci Securement Point	(6624, -3666)	Iron River
West of Tall Grass Inn	(3394, -4767)	Chalk Peak
Northeast of Sunshine Farm	(4004.80, 147.09)	Blackheart

The Once Human Horizontal Portal Guide encourages you to explore with purpose. You’re not just hunting down coordinates—you’re unlocking the future of fast base navigation. 

Once Human Horizontal Portal: Using the Strange Door Deviant 

Strange Door

Once you’ve wrangled the Strange Door Deviant, don’t just leave it in your inventory like yesterday’s loot. This eccentric little entity needs a proper home—specifically, an Isolated Securement Unit at your base. Think of it as a high-tech terrarium where the Deviant can thrive and do what it does best: make Shattered Strange Doors. According to the Once Human Horizontal Portal Guide, without this setup, you’re not crafting any portals—horizontal or otherwise. 

To keep things running smoothly, the Strange Door Deviant must stay charged with at least 30 Deviant Power. If it drops below that threshold, production halts like a vending machine out of snacks. You can fine-tune this limit from the Securement Unit’s settings, which is helpful if you’re trying to stretch power across multiple crafting Deviants. The Once Human Horizontal Portal Guide makes it clear: managing that power threshold is key to keeping your teleportation ambitions on schedule. 

But wait—this Deviant has preferences. Weird ones. It works harder when surrounded by red light, blue light, and flowers. That’s not flavor text; those are Mood Boosters that increase its production speed. If your base looks like a disco garden, you’re doing it right. Use the Once Human Horizontal Portal Guide as your roadmap to maximize efficiency, aesthetics, and strange, interdimensional door farming.

Once Human Horizontal Portal: Crafting the Horizontal Portal 

To craft a Horizontal Portal, you’ll need more than just curiosity and a free afternoon—you’ll need the right materials and a solid understanding of the building system. Open your Building menu by pressing ‘B’, then dive into the Function Facility tab. From there, you can right-click to place either a Standing or Horizontal Portal under the Facilities category. For the Once Human Horizontal Portal Guide, knowing where to click is half the battle—and not accidentally building a fence instead is the other half. 

The required materials are specific but manageable if you’ve been prepping. You’ll need 20 Shattered Strange Doors, which are passively produced by your moody little Strange Door Deviant. Then grab 4 Acid (possibly mass-produced with the Sulfur Chemist specialization), 3 Glass, and 20 Steel Ingots. Most of these are midgame-tier materials, so don’t expect to throw it all together in your first week unless you’re speedrunning like a caffeine-fueled deviant yourself. Every entry in the Once Human Horizontal Portal Guide assumes you’re balancing time, power, and material stockpiles—and this section is no different. 

Because the recipe is the same for both Standing and Horizontal variants, choose based on your base layout and not the material list. If your setup sprawls like a lazy snake sunbathing across a cliff, Horizontal Portals are your answer. If it’s more vertical and compact, go with Standing. The Once Human Horizontal Portal Guide reminds players that only one portal set can be active per base, so plan your blueprint wisely or risk building a door to nowhere. 

Item	Quantity Needed
Shattered Strange Doors	20
Acid	4
Glass	3
Steel Ingots	20

Once Human Horizontal Portal: Using the Horizontal Portal 

Using a Horizontal Portal in Once Human is like installing a teleporting trapdoor in your house—except this one comes with style, cooldowns, and limited uses. You can place Horizontal Portals on any flat surface, from the floor of your crafting hut to the roof of your greenhouse. Just remember, once you place a second portal, it links directly to the first. No spaghetti networks here—only point-to-point travel. This one-to-one rule is the backbone of the Once Human Horizontal Portal Guide and makes portal management more strategic than chaotic. 

You’re not locked into a single style either. Mix Standing and Horizontal Portals however you like; the system doesn’t care if you want to connect a doorway to the floor. You can even place portals in a friend’s base—provided you have permission—making cooperative hive setups much easier. Just don’t expect to zip across the map like a sci-fi courier. Portals are local only, for base travel and shared hive layouts. The Once Human Horizontal Portal Guide emphasizes this so you don’t accidentally run 5,000 meters to realize your portal won’t beam you back to town. 

Each portal has a limited number of uses—somewhere in the ballpark of 10 to 20. There’s also a short cooldown after each jump, and every user eats up a charge. So yes, if your hive-mates are overly enthusiastic, your carefully built shortcut could run out faster than expected. Smart players add signs from vendors in places like Deadvil or Tall Grass to label each destination. The Once Human Horizontal Portal Guide recommends this to avoid confusion and mid-teleport regret when someone walks into your storage room thinking it leads to the reactor.

Connection Type	One-to-one only
Compatibility	Works with Standing Portals
Build Zones	Own base or friend’s base (with permissions)
Travel Range	Local only (no world fast travel)

Once Human Horizontal Portal: Placement Considerations 

When it comes to placing a Horizontal Portal, think of it like dropping a trapdoor into your base layout—clean, flat, and ready to warp you somewhere useful. These portals are far less temperamental than their upright cousins, which tend to throw a fit if they sense a pebble, a shadow, or an overconfident wall nearby. Horizontal Portals, on the other hand, are happy to sit on floors, rooftops, or any other flat surface you can build on. That alone makes them a favorite in the Once Human Horizontal Portal Guide. 

Now, while the Standing Portal often struggles with walls and their decorative trims—especially the kind that have thick baseboards or sneaky snap points—the Horizontal Portal avoids most of that drama. It’s flat, it doesn’t need a view, and it rarely argues with your base layout. This ease of placement gives players a lot more creative freedom when building travel routes between workbenches, storage areas, or multi-floor builds. That’s why the Once Human Horizontal Portal Guide recommends it for tight indoor spaces where a Standing Portal might have a meltdown. 

Before locking down your portal placement, consider how you and your hive-mates will move around. Avoid cramming portals into tight corners or directly in front of high-traffic stations like the smelter or workshop. A poorly placed portal might save a few seconds of travel but cause long-term chaos as players bump into each other—or worse, accidentally teleport into a doorway. Smart placement is just as important as functionality, and the Once Human Horizontal Portal Guide pushes for thoughtful design over convenience alone. 

Consideration	Details
Surface Type	Flat surfaces only (floors, rooftops)
Obstruction Sensitivity	Low (rarely conflicts with walls or decor)
Comparison to Standing Portal	Easier to place; less fussy with surrounding objects
Ideal Locations	Near high-traffic facilities, entrances, and multi-floor transitions
Avoid Placement	Tight corners, directly in front of doors, or overlapping utility stations

If you’re building for speed, simplicity, and sanity, Horizontal Portals will become your go-to teleportation tool—and with the Once Human Horizontal Portal Guide in your back pocket, you’re less likely to send someone flying into your furnace by mistake. 

Once Human Horizontal Portal: Summary 

Horizontal Portals are more than just flashy sci-fi floor panels—they’re practical, reliable, and essential for any well-organized base in Once Human. Whether you’re sprinting between your refinery and your storage room or linking up with your hive-mates, these portals turn a long jog into a satisfying hop. The Once Human Horizontal Portal Guide highlights them as a must-have for any player serious about efficiency and convenience. 

To build one, you’ll need to first capture the Strange Door Deviant and keep it comfortable enough to produce Shattered Strange Doors. That means proper containment and a touch of ambiance—flowers, lights, and all. Once you’ve got the materials, craft your portal through the Building menu using a recipe that demands steel, acid, and just a little patience. The Once Human Horizontal Portal Guide makes it clear: preparation is everything. 

Horizontal Portals work in pairs, creating direct links that are perfect for internal travel or connecting with friends’ bases in your hive. They’re easy to place on flat surfaces and far less finicky than Standing Portals, which tend to get into arguments with walls. Just keep in mind the usage limits and cooldowns. Used wisely, they’ll streamline your base navigation and reduce the downtime between gathering, crafting, and shooting things in the face—which is really what survival’s all about. 

Feature	Details
Main Use	Fast travel within or between bases (hive-compatible)
Requirement	Strange Door Deviant and crafting materials
Crafting Location	Building menu > Function Facility tab
Usage Rules	One-to-one links only, limited uses, cooldown after each use
Placement	Flat surfaces only, smoother than Standing Portals
