What is the War Games Jam?

The War Games Jam asks participating teams to create an innovative war video game inspired by IWM’s collections and stories of conflict from 1914 to the present. It was developed by the IWM Institute, IWM's research, development and knowledge exchange hub in partnership with the Historical Games Network and the University of Glasgow Games and Gaming Lab. It forms part of IWM's War Games season


What are we looking for?

We’d like to see games which feature unexpected and under-explored stories of conflict, embracing creativity, empathy and diversity in their design and challenging our expectations of what war video games can be.

Is there a theme?

Each video game must be inspired by one of our specially-selected IWM collection items now viewable here

It is up to competitors how tightly or loosely they wish to stick to the object’s story or weave the object into the game - ‘inspired by’ can mean many things and we are interested in thought-provoking and lateral interpretations, as long as they are clear and rationalised, and topics are handled in a sensitive manner.

What are the dates?

Starts: Monday 13 February, 9AM

Ends: Monday 20 February, 8PM
