* Seeing as you cannot upgrade Processing Power, you should make sure to Flezz grind every once in a while to get new Hardware. Get a graphics card before taking on level 5-6 forums, and just upgrade from there.

* Hackers have some of the weakest attacks in the game, barring Permanoobs and Re-Res. Make sure to keep up with this with Hardware, .moar files, and buffing your Offense stat.

* As far as secondary stats go, focus on Frugality in the beginning, but as the game goes on, make sure to get Upkeep to at least 7 so your equipment doesn’t degrade. You have the most equipment of any clbum in the game; repairs are a ****.
