About
Undead Onslaught is an intense, fast-paced Bullet Heaven Roguelike where you don the mantle of a villainous warlord, wielding dark magic and overwhelming power against the forces of light. Crush your enemies, evolve your abilities, and carve your legend in blood and fire.
Break free from the traditional hero narrative and dive into a world where your rise from a nefarious disruptor of peace to the ultimate challenger of the celestial order is just the beginning.
In Undead Onslaught, experience a unique blend of high-octane bullet-hell action combined with the strategic depth of classic RPGs. Each choice and battle shapes your path through a world filled with formidable foes and breathtaking challenges. Will you master forbidden magic, wield legendary weapons, or lead an army of darkness? The choice is yours.

Loved this game! Even it's not my type of game and usually I avoid time killers, but this one has some charm to it. Definitely must try for the genre fans. The game is constantly getting updates, the small team behind this is just fantastic, always listening to community and taking feedback, in their Discord channel. So, if you are active - you are also part of the development, for the early access, it's just the perfect formula!! Most importantly costs really cheap so go and try it, nothing to lose! Looking forward to see how it will develop and I'm sure their next project will be even more ambitious. GL HF, a_Shot
Survivors + Metal = 👍
Got that great "Just one more game..." feel.
This game was fun on release but since then the def nerfed all the fun out of it
thrilling and badass game, this gem needs recognition
Fun and intense gameplay and creative progression. Loved it!!
^_^ I've been absolutely hooked on Undead Onslaught. The gameplay feels so smooth — every movement and action just clicks perfectly, and it makes it insanely hard to put down. The OST is absolute BADASS — every track slaps so hard it feels illegal. Some of the songs get stuck in my head for hours, and honestly, I’m not even mad about it. The character progression system is way deeper than I expected too. So many different ways to build your character depending on how you wanna play. Honestly can’t wait for more maps and new characters to drop. Huge props to the devs — y’all crushed it. P.S. The Only-Fans ability name is pure genius :3
This game just feels bad. The hitboxes make no sense and your character's attacks are so painfully slow, even when stacking cooldown reduction. Might get better if you work on the metaprogression, but it's not going to be a fun grind. This game just misses what makes the vampires games fun. It feels janky and uninteresting. You know when you just randomly find and buy these kinds of games and find yourself thinking that this game is fundamentally worse than many of the others? This is that.
1.) You get to play as the Villain. That's bloody awesome. 2.) The weapons and whatnot are unique and enjoyable to use. 3.) It's still in Early Access, so there's more to look forward to. 4.) The music is fantastic, and I haven't gotten tired of it. 5.) The community is helpful. 6.) You really can't go wrong, especially given the price point. I absolutely love the genre. My only regret, is that I hadn't tried the game sooner. As it has been in my library for a while now. Better late than never though. Now if you'll excuse me, I need to go back to slaughtering these filthy hero's.
This is a non-stop thrill ride! The action is intense, the graphics are gritty and immersive, and the gameplay keeps you hooked with satisfying combat and smart survival mechanics.
