Hacknet is free for keepsies if you nab it promptly
When ‘s tutorial told me I needed to kill its process in order to progress, I couldn’t bring myself to do it. Not out of sympathy for a sentient piece of software – this isn’t . I’m reasonably confident the tutorial was just a lifeless bit of code, I just couldn’t do it because I’m a terrible hacker who can’t tell a firewall from a floppy.
Maybe you’re fare better. If you download Hacknet before 6pm BST on Saturday, you’ll get to keep for free. No nethacking required.
