The RX4 Storm is a coupon reward. It is available for 50 coupons. If bought with coupons, it is only temporary for 30 days if exchanged for coupons.
So, I sprayed a lot in this video to show the actual effectiveness of this weapon as if it were being used by the average Crossfire player, who would spray a bit more than I would. Also, for the gameplay, I was recording in UK server 3 by accident after playing with NanoCooper, so that is the reason why I was spraying a lot and getting less reg than normal.
