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?

I'd say it's positive as of update 1.4 but I could see the argument to flip to negative Leaning positive because I don't feel ripped off for the price, though it could certainly be more Positive - good base to the game - decent character and meta progression - good variety of characters and skills - good art and designs - most weapons and items are totally usable - enough rng manipulation to not end up screwed with builds - able to disable a bunch of items you don't want to show up Negatives - only two maps, gets kinda old - some characters are hardly usable while others are godlike - second map design is really tedious to navigate - repetitive - grind is slow, forcing repetition - every run feels roughly the same, not much variation - longer runs (30m), not terrible but drags on with the maps/repetiton Things that would make the game excellent - 5+ more maps that aren't as tedious as #2 is, dividers are way too long - fix up weaker characters - shorter resource grind but more tiers to unlock - expedited rounds in some fashion, able to do a run in 15m or so would be great - less space between things on the map - less events that are just standing in a circle waiting out a timer Disclaimer: I did speed up meta resource progression since it was just redoing the same thing repetedly, game is balanced for high meta progression and somewhat overtuned early on. Feels good at high meta levels but it would take significantly longer than I have logged to achieve normally.
우리가 아는 그맛인데 너무 익숙해서 재미를 못느낌. 새로운거나 아니면 먼가 재밌는거 있으면 해볼텐데 없어서 그냥 환불함.
This is hands down one of the most faithful and also innovative "Survivorlikes" I have played. - Genuinely distinct character classes with unique skills and abilities. - Novel implementations of talents per character and other meta-progression - Unique world events and quests to interact with during a run
I’ve just started playing Undead Onslaught, but as someone who’s spent a lot of time with bullet heaven and roguelike games, I can already tell this one is something special. The villain perspective is a refreshing twist — instead of being the chosen hero, you’re wielding forbidden power and it makes every victory feel darker and more satisfying. Even early on, the characters feel distinct and strong; Vespera weaving shadows and Zargoth calling storms already stand out. The gameplay hits that sweet spot between chaos and control. The screen floods with projectiles, but it never feels mindless — builds and evolutions actually matter, and I can see a ton of depth waiting to be explored the more I push into runs. That’s the kind of design that keeps me hooked in these games. And I’ve got to say, the music nails the atmosphere. Dark, heavy tracks during battles and eerie tones in quieter moments add a lot to the experience. It makes those clutch dodges and power spikes feel even more epic. So far, Undead Onslaught feels like a game I’ll be sticking with — intense, stylish, and made for players who love testing themselves against pure chaos.
so well done, lots of potential but already super high quality / brimming with content
