Thanks man...went through and added up all the points I needed to upgrade everything. During my hardcore playthrough I upgraded the oppressor to level 3, the machine gun to level 2, and the sniper to level 2. I also upgraded the jetpack to level 3. So with that I needed around 93k points total. Although I had close to 20k when I completed my hardcore playthrough. Once I accumulated all those need tech points, I then disconnected from live and starting upgrading using an in game locker - starting with the machine gun and working left to right then onto the bottom row. Also, during my TECH farming on 2-4, I would complete the level as on Casual those ARCONS can be wiped out with the rockets from your jet pack very easily. Its an extra 4 or 5 minutes, but you get another 1500 points.
