Here's a new crate - the Royal Flush Crate
brings a new skin for Reaper making him look a bit steampunk-y as well as a pretty cool KN-44 remodel. The remaining epics use the new "Stampede" animated camo which definitely looks great on the SMRS but doesn't work on much else.
The rare camos are interesting because the designers managed to make every item look different despite using the same color scheme. They're actually quite nice!
