Lockstone Mountains is a top-down, action-adventure game in which you Pilot large flying vessels in inhospitable skies. These floating ships are controlled using a signature rudder-and-keel system with a physics-based flying model. Guns, cannons, missile launchers and much more are at your disposition to fight back swarms of enemies. Sails the winds along with other members of the Rook expedition, and uncover the secrets of the Lockstone Mountains, which is set in a hard-fantasy science-based steampunk setting, fully made using GameMaker.
The wealth of dangers roaming the skies are only matched by the expedition's ingenuity. Expand your arsenal to counter every threat you discover. From small mounted rifles to high-yield proximity detonated missiles, the sky is quite literally the limit! Every hull has a unique combination of hardpoints, each with weapon classes and a set cone of fire. Experiment with hulls and loadouts to find the combination that works for you!
Embark on expeditions to different island clusters in this strange new region. Discover lifeforms that inhabit the storm and uncover the fate of an ancient civilisation. Will you learn from their mistake and find your way home?
I am a solo developper that has worked on this game on and off for a few years. Learning gamedev through this project has been quite an adventure, and I hope you'll enjoy my first release!
