- You shouldn't try to max, or even upgrade, all of the special weapons. Just pick 3 or 4 that match your playing style as you go through.
- If you find you need some late-game cash, there are two options: Play Beast Hunter at the Uptown TV station for 4000Z every 45 seconds risk-free or do the following, less soul-crushingly repetitive method: Go to Cardon Ruins with the Vacuum Arm equipped. Enter the first big room and shoot all of the hornet nests. Absorb all the Zenny. Should net you about 8000 per 2 minute run, and this one has an element of danger!
