Does difficulty influence drop/spawnrates?

[Zero]

I was playing a game on HNTR just now (AoM) and noticed alot more rare stuff dropping, globes seemed less frequent. Before I was playing on ITYTD, I had only found the "jackal" unique in quite some games, but in this AoM game I found 2 fastload rocketlaunchers, one fastload chaingun (on level 2), phaseshift boots and armor. Aside from that I found *alot* more weaponmods. So, was I just incredably mad lucky or does difficulty influence droprates?

It does. At least drop quality.
