Accesss Nodes????

Yes they are in all areas (accept Richland of course).  Look for a green lightning bolt (sorta), shooting into the sky.  At the bottom of that bolt is the node you need to hack with the appropriate access key.  You'll get some fat XP and the area will no longer be restricted to you.  Also lvl 255 Agents will no longer show up to drop you like a bad habit!  Ever been standing around one second, then dead the next and wondered what the heck happened?  Level 255 Agent!  Like Aquatium said, there are many helpful sites to guide you to find the keys and then the nodes to hack.  (You don't need to be a hacker, just have the key).

Actually, I was just giving the person who started this thread a little more detailed answer.  As far as fighting level 255 Agents goes. . .have and knocked the bugger around but good!  Didn't really do any damage but he knew he'd been in a fight baby yeah!!  Also I would love to get as many level 50's together as possible to kill, YES KILL, a level 255 Agent.  Before I get a tongue lashing I'll explain where this idea came from.  My FM Amiga managed to kill a Sentry in Zero-One.  With help of course.  So who wants to try the Agents?!

How's that for lazy?

Oh yeah and sometimes I just hang around after a mission 'till one or more shows up as well.  Oh!  You said they're lazy.  Thought you meant me Enon.  Read that too fast!  My bad.  You've only seen two?  Strange.  If I hang around long enough things get. . .well. . .hairy.

I'll take screenshots of their dead bodies and then of me wearing their glasses!LOL!
