Characters rise to the occasion to sacrifice themselves for the greater good, summon their bravery to take a stand against the aliens, and learn to think first and act later, even if they're usually impetuous people. Although violence is the story's ultimate problem-solver, Battleship is still a story of courage under fire and cooperating to target a common enemy.

As with most alien-invasion films, there's a huge body count. The aliens wipe out two entire ships, destroy a number of buildings, and cause widespread deaths in Hawaii and China, as well as worldwide panic. A few well-liked secondary characters die. Lots of explosions and gun violence, as well as some minor brawling among the rival naval officers. Characters are shown bloodied from close calls, as well as moments before their ships explode.

A few passionate kisses, a shot of a couple in bed, and the male star is shown wearing just a towel after coming out of the shower. One female character wears particularly tight or revealing clothes, even when she's working as a physical therapist. In one scene, she kisses her boyfriend while wearing only a string bikini top and very short shorts.

Two implied uses of "motherf--er" (the last part is covered up by an explosion both times). Other words include "s--t," "ass," "hell," "bitch," "damn," "idiot," "oh my God," "goddamn," and the like.

The movie is based on the Hasbro board game, and Hasbro is credited as one of the production companies. There's one segment in which grid coordinates are called out just like in the game. Otherwise, there aren't any major product placements within the movie itself -- but there lots of tie-in products available, from special editions of the board game to first-person shooter video games, apps, toys, and more.

Some drinking early in the film: Adult brothers do shots for a birthday at a bar where others are also consuming alcohol. The main character gets drunk and makes some iffy decisions as a result.
