Well, the possibilities are endless. We could have a special tiki weapon, or a fiery set (goes with Fiery Antenna). I'd like to see that.
Who knows, there might be some codes you have that you are not revealing to us yet.
The fire set is unrealistic. The Doom weapons already fit well enough with the antenna. There's no need for a complete "set". The special tiki weapons have already been made. (I.e. the contest winners) I understand y'all want more freebies, but seriously, just play the game. We got a free item, and now were pushing for even more. I would be fine with one special item per campaign. If they overuse the use of the promo codes, it kind of defeats the purpose of "promo".
