FN p90 is best used on PC when playing era on facebook or the website. It rivals the minigun in speed if you click with your mouse. I used it quite a bit while basing at times and ive beaten a flamethrower user 1 on 1. But the biggest downside when doing this is that you end up being immobile. Fn p90 on ios is okay but to be honest I wouldn't buy it if I mainly use an ios device. I would either pick the socom or save a bit more and buy the Bushmaster ACR that gun is very well rounded.
