The Highpoint Expansion is now available for free to The Solus Project on PC, and will be released tomorrow on Xbox One, Grip Digital and Teotl Studios have announced.
The new content sees players exploring the "very vertical Highpoint island, along with its accompanying massive cave level". Players are promised more than three hours of additional story and gameplay including acid lakes, dozens of strange flying orbs, a monstrous creature, and a massive windmill.
Accompanying the new content is a patch which promises to fix a host of known bugs.
The Solus Project will exit Steam Early Access and Xbox Game Preview Program next month.
