About this game

# What is B100X?
B100X is an "auto dungeon RPG" that you can easily enjoy during your free time.
This game was created with the concept of "making hack-and-slash accessible to everyone."
With "Full Auto Battle" and "Anything Synthesis System", both easy operation and complicated capture are compatible.
There is also an automatic lap function, so you can enjoy it even during matching of competitive games.

# Seal the Eternal Cave
In the world before the birth of mankind, the heavens were dominated by God and the earth was dominated by demons.
The player becomes a "witness" who assists the apostle "Holly" of God, and challenges the seal of the "Eternal Magic Cave", which is a terrifying monster's nest.
What is a demon? What is God's true purpose? What is the relationship between the Holly Apostles and humans?

# How to play
- Create play data.
- Choose a dungeon and a target floor and start your adventure!
- The battle is completely automatic.
- Use experience points, junk, and drop items to strengthen Holly!
- Aim for the deepest part of the "Eternal Cave".

There is also a PC/iOS version.

I really like this game. like other reviews have said, the English isn't perfect, but there's plenty of potential depth in the game. The gameplay is really a matter of setting up your apostle to go as many levels as they can manage. You only watch as they do their best to clear battles and floors with the gear they've found along with skills you've equipped them with. There's a model of a girl that's... let's say, "top heavy"... but looking beyond that, it's a fun game to tinker around in.

Numbers game, loot drops, item fusions to make more powerful ones, etc. Simple design, with good explanations to stuff. Good game to sink hours into, and easy to put down as you have complete control of your journey. 5 stars. Will edit again if needed. *Edit on 18/9/2025. Game still good, got back to it after years. Lost my original save but it's okay. Bcoz the translation seems to improved and I can actually follow the plot now. Satisfying game, for those who likes getting powerful.

Amazing game, I was able farm, test, and utilize all sorts of stats that fit to my prefence for fighting, and to be honest I find the gameplay to be 10/10. I was able to make it to floor 1000 within 48 hours of gameplay, plus No ads! Completely free to play, the difficult was not at all that bad, but I will say I am glad I learned early on that the items you get from missions are freakn RARE. So any new players that read this, be careful when using it becuse you never know when you'll get more.
