At first glance, Re-Mission comes across as a stylishly produced, anime-influenced video game. But the targets in question are cancer cells, which the character Roxxi the nanobot blasts with the Chemoblaster, the Radiation Gun, and the Antibiotic Rocket.

Re-Mission is specifically designed as a health improvement intervention for teens and young adults who have cancer. Game producers at HopeLab start with a desired health outcome, and then reverse engineer a game that encourages positive behaviors, adding motivation and fun into something as scary as a kid's battle against cancer.
