Crossover missions also added as free DLC

Bandai Namco Entertainment will add God Eater missions and costumes to its Ansatsu Kyōshitsu: Koro-sensei Dai Hōimō (Assassination Classroom Koro-sensei Great Besiegement) Nintendo 3DS game on July 16. The new contents are free to download.

In the two special "Mission Time" crossover missions, players control the students as they attempt to kill Koro-sensei in God Eater's Ogretail headgear within the time limit. In the "Counterattack Time" mission, they control Koro-sensei himself.

Players who clear these missions will receive the crossover costumes. Male characters can put on Lindow's hair and costume, while female characters can put on Alisa's hair and costume. Koro-sensei's Ogretail headgear is also available.

In the "comical assassin action" game, players create their own avatar to become a student of class 3-E, interact with the characters from the manga, and set traps to try to kill their teacher. Missions are cleared if the player assassinates Koro-sensei within the time limit. When missions begin, the player must look around the map for items, traps and weapons to use to complete their goal. Weapons include hand guns, knives, grenades, and even a rocket launcher. Some traps can hurt Koro-sensei, while other items, such as gelato, juice, or erotic books can stall him. Classmates can team up, and Koro-sensei can attack back.

The game shipped on March 12. First printings came with a download code for a Koro-sensei 3DS theme.

The game is based on the Yusei Matsui's Assassination Classroom manga. Viz Media publishes the manga in North America and describes the story:

A humorous and action-packed story about a class of misfits who are trying to kill their new teacher – an alien octopus with bizarre powers and super strength! The teacher has just destroyed the moon and is threatening to destroy the earth – unless his students can destroy him first. What makes things more complicated is that he's the best teacher they've ever had!

The television anime of Assassination Classroom premiered on January 9. Funimation streamed the first season as it aired, and the second season will premiere in 2016. A live-action film opened on March 21.

Matsui launched Assassination Classroom in Shueisha's Weekly Shonen Jump magazine in 2012. It inspired an event anime in 2013.
