We went through and added the Quickfire Katana schematic to everyone who's joined us through Early Access so far. It's essentially a cooler looking version of the Inferno Katana - a little vanity item for you guys to show our thanks for getting involved and supporting us so early in our development process.
The Katana will be available to anyone who puchases Minimum all the way until we exit Early Access, and we'll look at other cool rewards for you guys down the road as well!
