Back here again. I'm putting you deeper in the Node this time, and I'm not sending any simple threats your way this time. Use your Sprites, Thread your moves, and get out of here.
Biggest thing to keep in mind are Spiders. Since we're in my Node, and I'll be trying to keep you out of some of my files, I'd be the Spider in this case. It's just the title of anyone who monitors a node for hackers. Good rule of thumb; the more expensive the server, the more likely that there'll be a Spider, potentially multiple. If you're lucky, their contract just involves setting off the alarms and reporting you to G.O.D., and they'll just try to boot you from the node. You aren't going to be lucky all too often. Keep in mind that a Spider is more than capable of setting off max level security measures if they find you, so DON'T GO ACTING LIKE A HOTSHOT. Remember, they're smarter than usual security measures, but they're metahuman. You can still trick them.
