Story: As it's not the most original story it's still one i enjoy, they manage to keep it intressting so that everything doesn't feel like it's the same episode all over again.
Art: The art style is much the same as other action animes, in Btooom! they manage to draw explosions very good.
Sound: The sound track was really good, it always keept me focused in the story and made me excited. The intro "No pain, No gain" is one of my favorite intro songs.
Character: They have a broad variet of characters, every thing from children to mercenaries.
Enjoyment: I love exciting animes with action, love and betrayal, and this anime has it all.
