Hacknet needs a Rezz ... something called like Runner Backup System or what ever and some "Apps" that attach the Character more Resist or higher Hackskill (could use it as Armor or Implants). It needs some more Caves and nicer Cybercreatures, where you can find the Codefragments for this "Apps". How a about a spawning Hacknet-Creature like the Chaoscave Queens or Grims?
Ok you need Area Damage things most people say but it could be fun for Hacknetteams.
