Surgeon Simulator 2013 will receive more updates, Bossa Studios has said.
3D artist Jack Good revealed that that the team has said it "definitely" has plans for more free content following the addition of Team Fortress 2 characters and Oculus Rift support last week.
"There's so many things we want to do," he told Digital Spy at PC and indie games expo Rezzed.
"We've got loads of ideas on the table, it's just how successful the game goes, to the point where we can carry around and can afford to keep making these updates."
He continued: "New operations, new tools, new environments - we've got the ambulance and the surgery, we've got some ideas for some more.
"We've got some interesting ones that we think would be really fun that we want to add."
Having just released Team Fortress 2 support, Good said that there is currently no schedule for the updates.
He added that the the team would "love" to do a sequel, but would have to justify it with all-new content.
"We want to see what we could do with it - we want to make sure we're doing it for the sake of it," he explained.
"We want to have new content, we want there to be a reason for a sequel if we did do one. We're just going to play it by ear and see what happens."
