About this game
Hex Core is a short incremental clicker game. PeteOS is your line of defense against viruses, and you’re working toward clearing them completely.
Between fights you funnel resources into a deep tree of upgrades that open new mechanics, weapons, and research paths. When you’re ready, you execute another run.
Each run climbs in difficulty and in what you earn, so turning the dial up always costs something and pays something back.
Features:
3 different game modes (Campaign, Blitz, Fork)
Large skill tree with over 900 upgrades
Simple yet engaging gameplay
Research system
Kernel Ops that provide resources for completing tasks
Controller support
Several accessibility features
Cute digital penguin
