The four game pitches that will enter a short prototyping phase as part of Double Fine’s Amnesia Fortnight have been revealed.

The four were selected from a field of 23 by members of the public who contributed to the Humble Amnesia Fortnight Bundle.

The successful pitches are: Hack ‘n Slash, a dungeon crawler in which the player builds exploits, trainers and hacks in order to progress; Spacebase, a space station city builder that provides home and work environments for aliens; The White Birch, an “ambient platform exploration game”; and Autonomous, an '80s-inspired first-person construction game.

Each project will be developed over the next two weeks, and the process will be streamed live.
