A company in Cambridge is developing a computer game based on the experiences of people living with psychosis.
Ninja Theory has spent the last two years speaking to people about their hallucinations so they can translate them to the small screen.
They have developed the game: 'Hellblade: Senua's Sacrifice', which is now almost complete.
The protagonist, Senua, is a celtic warrior whose lover was killed in a Viking invasion.
The trauma has led her to develop psychosis - she sees visions and hears voices.
The team at Ninja Theory developed the game in line with feedback from those living with psychosis.
Rachel Waddington began seeing visions when she was just seven-years-old.
Now, more than 30 years on, she lives with visions and voices every day.
The aim of the game is still enjoyment - but it's hoped will help to change perceptions of metal illness.
