Those gifts are a bastard to get. Played for a few hours myself this night and only managed to get one mask. What locations have you seen gifts spawn in, SEH? The one I found was under the ladder leading up to the roof on CP #2. I also THINK I saw a dude grab one right behind CP #1, up on that raised platform where the defenders can drop down.
Also hope that the unusual metal remains in your inventory and can be crafted with after the Halloween event, because I just barely have 2 refined now and I'd rather make a hat with it when I get up to 4. Assuming I manage to get unusual metal before the event ends.
Had the mask for 20 pumpkins from last year's Halloween so I dunno if it's working properly this year or not.
Hmmn, I forgot you could tempt me with things I want.
