nullptr is an action puzzle game where you play the role of a hacker. Your goal is to take down mega-corporations by invading their servers to download and destroy their data. This is no easy task since these servers are populated by sentinel programs that will try to trace and eliminate you. So you'll need to use your hacking skills to find safe routes, bypass security systems, manipulate data and sentinels to reach your goal.
Testing the route profile mechanic where the route you take affects what areas you access. If there is no perfect route, you can build it by manipulating data and using the stack memory.
