You’ve now got 4 ctOS boxes to hack around the neighbourhood. Two of these have hacker puzzles guarding them, but these are simple join the dots varieties that shouldn’t cause you any issues.
Another is just a case of walking up and hacking it, no problem, and the last is in restricted gang territory, which you can just send the Jumper into to get the job done. Once they’re hacked, that’s you.
