Nullptr

Nullptr is a real-time tactical hacking puzzle game in which your actions reshape each challenge. You infiltrate megacorporate servers, reroute connections and collect data while trying to outmaneuver adaptive defenses and beat the clock.

Hacking systems

Each infiltration gives you 20 seconds before the trace monitor locks you out. Your movement leaves a visible trace, which you can erase by retracing your route to reduce your exposure. The stack memory system lets you store, reorder and rewrite data nodes to change the environment.

Sentinels, gates and firewalls respond to your behavior. You can also use these defenses as tools, and find loopholes that let you turn threats into opportunities.

Stages and runs

The game has over 125 handcrafted stages across four megacorporations, each with its own security systems. You can complete servers without detection in ghost runs, recording your best times.

Visual style

Nullptr uses a minimalist, high-contrast cyberpunk aesthetic inspired by classic terminals and retro hacking culture.
