Ruyn HD is a remake of my minimalist boomer shooter Ruyn, rebuilt in Unreal Engine 5. It keeps the fast, combo-driven gameplay of the original, but now features modern visuals, smoother controls, updated audio, and tighter gunplay. Ruyn Classic and the 2D and 3D level editors are included.

About
What is it?
Ruyn HD is a remake of my minimalist boomer shooter Ruyn, rebuilt in Unreal Engine 5. It keeps the fast, combo-driven gameplay of the original, but now features more modern visuals, smoother controls, updated audio, and tighter gameplay.
The levels are short, intense, and built for momentum—just you, some weapons, and a ton of enemies to blast through. The focus is on pure, simple shooter mechanics: fast movement and nonstop action.
The original Ruyn Classic is included, and the level editors work across both versions, so you can build once and play in either style.
Ruyn HD is 100% free — no ads, no microtransactions, no DRM.
The original Ruyn Classic, the 2D/3D level editors, and the launcher are all open source and public domain. The HD version's Unreal Engine code is not open source due to engine licensing restrictions, but everything else is yours to modify, share, or build on.
How do I play it?
The basic goal is simple: eliminate all enemies and reach the exit.
If you're chasing a high score, it’s all about speed, variety, and combo flow.
Each time you kill an enemy, a combo bar appears at the top of the screen—it drains quickly. Kill another enemy or collect a gem before it runs out to keep your multiplier alive. The longer you maintain it, the higher your score climbs.
But there’s more: the game rewards creative kills. Use different weapons or methods to earn style bonuses. Repeating the same kill type will reduce the bonus—so keep it fresh if you want to score big.
There’s also a bonus for finishing the level quickly, so don’t hang around too long.
Note: Ammo is shared over multiple weapons. When you collect some shells, you have access to the shotgun and double barrel shotgun straight away. This works the same for the plasma which is shared across the plasma rifle and trident.
Tip: Use the single-barrel shotgun when you need something that fires fast and the double-barrel shotgun when you need more grunt. This can help when you're trying to keep up a combo.
How do I make and share my own levels?
You can find detailed tutorials on how to build your levels here on github gists(See Online Manual URL on this page) and in the community hub.

great game!!
Se ve interesante, pero va atascado y los controles están raros, y lo puedo comprendo porque es nuevo y gratuito, pero lo arruinaron al usar UE, esa cosa arruina los juegos.
Good old fashioned fun! Short if you're good at this type of game and lacks any story but it's pure fun.
Simple and fun game. It achieves everything it sets out to do, so I would recommend it to anyone who is a fan a classic FPS games. There is a solid instrumental metal soundtrack throughout, too. The weapons are the basic archetypes you'd expect in a FPS game, but they do the job. The enemies are heavily inspired by doom and I can recall a pinky demon and mancubus. The enemies feature different death animations depending on where you shoot them, which is a nice touch. The death animations are also great and satisfying to watch. It's free, so you might as well just try it! 7/10
Самый дешёвый закос под DOOM на анриле. Я могу дать своему младшему брату компьютер и бесплатные уроки по Unreal Engine с ютюба. Он справится, и то лучше
No options at all for controls, no possible to invert mouse.
My older brother, Khris, asked me to download and play your game. Apparently, he is a friend of yours. Anyway, I really like the game. The whole shotguns thing is cool. The people who keep saying its a DOOM ripoff are kinda stupid. Like it isn't already very obvious that its DOOM inspired? Not to mention free... they just need to touch some grass and get actual human contact.
Okay. A little piece of advice. If you´re not hunting for them achievements like me, stay away from the Classic version. I mean it. It´s the worst. The mouse doesn´t work properly and the music is so bad it almost made my ears bleed. It somehow made the 44 minutes it took me to get through it feel like 44 years. The HD version is a different story however, and it was a very pleasant surprise that washed away the disgusting taste the Classic version left in my mouth. The music is awesome, the gunplay is awesome, and best of all.....THE MOUSE WORKS LIKE IT´S SUPPOSED TO!!!!! The only complaint I have about the HD version is that sometimes the input to fire the gun doesn´t register, which did kill me a few times, but I´d take that any day over the horrendous aim of the Classic version. So yeah. Play the HD, stay away from the Classic. Unless you want all the achievements. In that case you have no choice but to play through it.
