Our Anomaly is the Remington Suppressor, a machine pistol that comes with an integrated suppressor (Hence the name) and has decent stats (Does damage on par with a low-end heavy pistol in both 4th and 5th edition) for a reasonable price (700 in 5th, 850 in forth. Ironically, that makes it cheaper than an ares predator in 5th but more than twice the price of one in 4th).
The anomaly crops up when we look at availability. In 5th ed it's 6R, which makes it fairly easy to get a hold of for most runners who want a good disposable silenced pistol. In 4th however, it comes in at a whopping 15R, making it unavailable in chargen and harder to lay your hands on than most mid-high end 'ware.
Why is there such a striking difference?
