Belle Fontiere wears a top that exposes much of her tummy.

There is some comical violence in some games, but in one game (an FPS shooter), there is some gunplay, but there isn't any blood except when Tari dies (in the game, not in real life) and the edges of the screen get covered with black blood. That is brief. I recommend watching this because there isn't very graphic violence and there's only one count of blood.

In Season 2, Episode 3, some battle vehicles have decals that look like blood on them.

Most episodes have a lot of uses of "goddamn it", excluding the ones rated TV-PG which have a few.

There's some uses of "goddamn" and "ass", but there aren't any S-words, B-words or F-bombs.

There is a scene where scientists working on Project Blue get exploded (there's only an alarm, some screaming and then an explosion). The explosion isn't graphic and it has no blood but the scene can be scary for some kids.

Many of the action sequences throughout the show are fast-paced and quite intense/dramatic.
