People who have spent so much time to get this mod is most likely to be a founder. And when they are founders they dont really care about plat. So might as well give up the thought of getting it through trade.
You never know, Primed CHamber might appear in one of the Suspicious Shipment alerts. They're giving a variety of interesting things away as rewards for them and DE always did say they wanted to re release Primed Chamber in a future event. This one fits the bill pretty well does it not?
dunnow if worth in the warframe case(not collectors case), lets about; warframe is an TPS game that didnt have a large landscapes outdoors places(yeah, u can go outside, but u dont have large landscapes with lots os opportunity to use an sniper). by other hand DE can improve the game a lil more and make a new update with maps "snipers based", but when that happens probably DE will launch a now mod that make the same of primed chamber and as response will change primed chamber to that mod names(since primed chamber dont have is own image and etc..) if i have one i would sell in a hurry for a rroud 5k-10k (the default price range for this mod).
I own a Primed chamber. As a ps4 player it is extremely rare. I payed 10,000p but most ppl wanted 15-20k plat. If it were re released it will be extremely limited quantity to best players in event or something
