The following image shows our projected major goals for the development period until the 1.0 release of GHPC, including the period in between Steam Early Access release and full release.
Roadmap items are roughly chronological and may be revisited as needed during actual development. Items are, of course, subject to change if necessary. All art is "pre-vis": real game assets in-engine, but posed for the screenshots where necessary.
