Legendary weapons drop rate

[Zero]

Over 70 hours of gameplay, all achievements unlocked for quite a while and I still haven't seen a single legendary weapon in that damn shop.

RNG's gonna RNG.. I've gotten Chaingun twice, Gattling Laser once, Seen Excalibur twice... Probably one every 10 or so runs.

Grab more luck if you want to see them more often, but its still a random occurrence.

The game is heavy on the RNG so it's all about it here, nothing we can do to help.
