For a manga about a guy who happens to be able to use features from a Free-2-play FPS in a fantasy world its pretty good. The main character as always is OP and has an HP regen of a god. Plus when combined with his abilty to spend crystals dropped by monsters as currency in his hud he is able to buy things instantly making him OP. Its got a good amount of battles and dungeon crawling so it definitely doesn't get boring. The artwork looks good and shows the intensity of the combat the MC encounters. The character design is nothing special but itsgood enough.

Its just another enjoyable in another world story but with guns.
