Re-did this to check perk rewards, since the Season 4 patch(1.0.499606) notes said this:
HORDE MODE
Rank 2 Universal Perk rewards on waves 30 and higher should now drop as intended.
Mostly just to show the rewards from this, abusing AOE weapons and lack of friendly fire. Doesn't seem any point to keep going as well, even if you didn't already have the rewards. I don't really see a difference from when I did this before the patch to after, so possibly the perk wasn't dropping for people who had it? There have been instances of the reward screen giving incorrect information, so maybe that's it.
Rewards: Air Machine Gun emote (Wave 10), Enhanced Reach 2 perk (Wave 20)
I'm pretty sure Enhanced Reach 2 drops randomly from campaign as well.
