UK game developer Bossa has made Surgeon Simulator 2 free for NHS staff.
"At Bossa, we've always envisioned Surgeon Simulator 2 as a valuable training tool for NHS workers to hone their healthcare skills!" Bossa boss Henrique Olifiers said.
"The Surgeon Simulator 2 community is frankly rubbish at saving Bob, so we think our players need to be shown how it's really done."
