Bloodthief demo update, the fast-paced vampire melee runner game is now sharper than ever on Linux and Windows PC. All thanks to the creative mind of solo developer Blargis. Experience fresh thrills at every corner, which you can play for Free on Steam.

Solo dev and YouTuber Blargis – yeah, the same guy whose devlogs have pulled in over 4 million views – just released a major Bloodthief demo update for Steam Next Fest. And if you’ve got a thirst for blood, speed, and medieval mayhem, this is worth sinking your teeth into.

You play as a relentless vampire tearing through haunted castles and grimy dungeons. It's a high-speed, first-person vampire melee runner. The game’s all about hacking, slashing, and sprinting your way to glory. Let’s be real: nothing feels better than vaulting off a wall, slicing through some cursed knight, and drinking their blood mid-air. This boosts your speed like a turbo-charged Dracula.

This isn’t just another dark fantasy romp. Every ounce of blood you collect fuels your powers and your speed. That’s right – the faster you kill, the faster you move. Whether you’re carving your path through hordes or discovering dark shortcuts, Bloodthief keeps the adrenaline pumping around every corner. This is powered by the exciting demo update.

Bloodthief - Official Demo Update Trailer

Now here’s the juicy bit: with the Bloodthief demo update, there’s a whole new level, a new bladed weapon (yes, it’s as brutal as it sounds), and three hidden artifacts you’ll need to find to unlock it. The demo takes about an hour to beat if you're just blasting through. If you're a completionist like me, expect up to 20 hours of exploring every dark corner, unlocking powerups, encountering enemy types, and unravelling the secrets that haunt the walls.

Oh, and Blargis isn’t stopping there. He’s kicking off a gameplay with a Speedrunning Challenge. It runs from June 9, 2025, at 10AM PST to June 16, 2025, at 11:59PM PST. Your mission? Complete a “Full Game Inbounds” run of the demo and post it on Speedrun.com. With this Bloodthief demo update here, if you’re fast enough – and I mean fangs-bared, pixel-perfect fast – you could also win one of five Steam gift cards. These range from $100 to $25.

Even if you don’t top the leaderboard, everyone who submits a valid run gets a custom Discord role and a special in-game badge when the full version launches. That’s some eternal bragging rights right there.

Here’s a taste of what you’re in for:

Speed is survival – wall-running, vaulting, and blood-boosting through levels at breakneck speed.

Combat that hits hard – chop, slash, and kick enemies across the map with a variety of brutal melee weapons.

Secrets behind every stone – discover hidden paths, unlock deadly new abilities, and reveal the chilling lore buried in these cursed halls.

Best part? With the Bloodthief update out now, the demo is fully playable on Linux and Windows PC via Steam, and it’s localized in a bunch of languages including English, French, German, Spanish, Brazilian Portuguese, Polish, Russian, Simplified Chinese, and Japanese.

Bloodthief, a “boomer slasher” game that combines speedy high-skill melee combat with modern movement mechanics, will launch for PC via Steam on September 22, developer Blargis announced.
