Serious games developer Virtual Heroes is working on a new first-person shooter sequel for Hope Lab's popular Re-Mission game, which has been distributed to cancer patients in 81 countries since 2006.

We're taking their existing concept and trying to raise the fun bar and creating more lifelike and enjoyable environments within the human body, explained Jerry Heneghan, CEO of Virtual Heroes.

Players will take control of Roxy, the protagonist, and have new weapons to battle cancer with thanks to input from cancer patients.

Virtual Heroes is also updating its HumanSim technology with a new human physiology engine, technology has been used by Duke Medical Center's nursing school to train nurses virtually.

Heneghan said he hopes this software will inspire gamers to turn to careers in healthcare and make people in the medical profession more proficient with more grants and funding flowing into universities for health games.
