The Hell Inside is an action roguelike taking place in familiar places turned unfamiliar.
Waking up with nothing but a book as a weapon, you must battle through hordes of monsters that do not seem to have a place here.
The book is your weapon, and your only one. Your life depends on it.
The book starts out as as a weak projectile, but with the power of adding pages with upgrades written on them, the book can change and morph into what is needed. Upgrades range drastically with some playing a more supportive role such as a laser sight or a more offensive role, like changing your projectiles into knives.
New pages can also be written by finding ink during runs. These pages can be written before a run starts to have a chance of dropping during the next run.
