You’re sneaking through the Blacksite, heart hammered against your ribs, trying to keep your light off so the Eyefestation doesn't melt your brain. Then you hear it. That smooth, gravelly, slightly arrogant voice coming from a blue-scaled, multi-armed entity behind a shop counter. If you've spent more than five minutes in the hit Roblox horror game Pressure, you know exactly who I’m talking about. Sebastian Solace isn’t just an NPC; he’s basically the face of the game. He’s sarcastic, he’s dangerous, and he’s got a voice that carries the entire atmosphere of the Hadal Blacksite.
So, who voices Sebastian in Pressure?
The man behind the gills is Gianni Matragrano.
If that name sounds familiar, it's because Gianni is everywhere in the indie gaming scene right now. He isn’t some random guy with a decent mic. He is a professional voice actor who has become a cult icon for playing "unhinged but charismatic" characters. Honestly, the moment Urbanshade (the developers of Pressure) announced he was playing Sebastian, the hype train left the station and hasn't slowed down since.
Why Gianni Matragrano is the perfect fit for Sebastian Solace
Casting is everything in a game like Pressure. You need someone who can sound like a monster but still keep you coming back to buy items. Gianni brings this weirdly specific energy. He’s known for a massive range, but his "Sebastian voice" sits in this sweet spot of being menacing yet strangely comforting. He’s the guy who will sell you a flashlight and then mock you for dying two rooms later.
Gianni’s most famous role—the one most people recognize him for—is Gabriel, Apostate of Hate from ULTRAKILL. If you’ve played that, you know he can do "furious angel" incredibly well. But for Sebastian, he dials it back. It’s more laid back. More "I’ve been trapped in this underwater hell-hole for years and I’m over it."

That’s the secret sauce.
A lot of Roblox games rely on text boxes or generic sound effects. Pressure stepped up by hiring a professional of Gianni’s caliber. It changes the vibe. It makes the world feel "real," or at least as real as a world where you're being hunted by giant fish-monsters can feel. Gianni has this way of delivering lines that feel like they weren't just read off a script; they feel lived in.
The lore connection: How the voice acting shapes the character
Sebastian isn't just a shopkeeper. He’s a Saboteur. He’s a victim of the Urbanshade experiments. When you listen to his dialogue—especially the rare lines or the way he reacts when you try to flash him with a beacon—you hear layers of resentment.
Gianni nails the "pissed-off scientist turned monster" trope.
Think about the way he says "Get that light out of my face." It’s not just an instruction. It’s a threat. You can hear the history of Sebastian’s trauma in the grit of Gianni's performance. It’s rare to see that level of depth in a Roblox title. Usually, you’re just dodging bricks or clicking circles. Here, the voice acting tells you that Sebastian is a person—or used to be—long before you ever read his file in the documents section.

People often compare him to characters like Cave Johnson from Portal or even some of the more snarky NPCs in Half-Life. He’s got that "I’m smarter than you, and we both know it" energy.
Where else have you heard the voice of Sebastian?
If you like the way Sebastian sounds, you should definitely check out Gianni’s other work. He’s a bit of a legend in the "voice acting meme" community, but his professional resume is honestly stacked.
- ULTRAKILL: As mentioned, he plays Gabriel. This is probably his most iconic role.
- Genshin Impact: He’s popped up in various roles there.
- Arknights: He’s voiced characters like Rat King.
- Warframe: He’s done work for this massive title as well.
- YouTube: He has a huge channel where he voices comic dubs and random memes, often showcasing his terrifyingly broad vocal range.
It’s actually kinda funny because a lot of people started playing Pressure specifically because they saw Gianni tweet about it. He has a very loyal fanbase. When he voices a character, that character instantly gets a certain level of "cool factor" attached to them.
The impact on Pressure’s popularity
Let’s be real for a second. Pressure is a great game. The mechanics are solid, the lighting is spooky, and the monster designs are top-tier. But would it be as popular without Sebastian? Probably not. And would Sebastian be as popular without Gianni? Definitely not.
The voice acting acts as a hook. It gives the player a central point of interest. In a game where most of the "characters" are trying to kill you in silence, having a talking companion (even an antagonistic one) makes the experience feel less lonely. It’s a classic game design trick—think of GLaDOS or Atlas—and it works perfectly here.

Gianni also interacts with the community quite a bit. He knows people love (and are slightly obsessed with) Sebastian. He’s played into it, which only helps the game grow. It’s a symbiotic relationship between the developer, the actor, and the fans.
How to find more Sebastian content
If you’re looking for more of that specific Sebastian Solace flavor, your best bet is to follow Gianni Matragrano on social media or YouTube. He occasionally drops "outtakes" or just riffs in the character's voice. Plus, the Pressure developers at Urbanshade are constantly updating the game, and new voice lines are a big part of what players look forward to in every major patch.
Basically, the "who voices Sebastian" question is the gateway into a whole world of indie voice acting talent. Gianni is the tip of the spear, but the fact that Roblox games are now hiring this level of talent says a lot about where the platform is going. It's not just "kids' stuff" anymore. It's a legitimate medium for storytelling.
What to do next if you're a Sebastian fan
If you want to dive deeper into the world of Pressure and the performance behind it, here is how you can actually engage with the community and the content:
- Check the Urbanshade Discord: They often post behind-the-scenes clips of the recording sessions. Hearing Gianni do the voice without the filters is actually pretty wild.
- Listen to the OST: The music in Pressure is designed to complement the voice acting. Pay attention to how the "shop theme" changes the mood when you're talking to Sebastian.
- Watch Gianni's "Gabriel" content: If you want to see the "angry" version of Sebastian's vocal range, his ULTRAKILL work is the gold standard.
- Read the Documents: Find the lore files in-game that explain Sebastian's transformation. Reading them while hearing his voice in your head makes the backstory much more impactful.
- Support the Game: If you want more high-quality voice acting in Roblox, supporting developers like Urbanshade who actually pay for professional talent is the best way to make it happen.
Stop flashing your beacon at him. He really doesn't like it. Go buy some batteries and get back to the run.
