The Leftfield Collection offers indie developers the chance to showcase their pre-release game, free-of-charge, at the event but spaces are very limited, and the selection process is extremely competitive. Developers interested in submitting their game for inclusion in the collection are asked to fill out the application form. Applications close on August 1st.

Some of the games featured in previous years Leftfield collection, including Joe Danger, Don’t Starve, and Proteus, have gone on to achieve commercial and critical success. The collection has also featured custom hardware and no-screen games; games such as GlowTag (a game which is a step up from conventional playground tag that uses PSMove controllers) and Line Wobbler (a one-dimensional dungeon crawler which utilizes a springy door stop-type contraption and an LED lighting strip).
