Revenge! Charity! Stamps! These will be the dominant market forces in Team Fortress 2's economy of death over the next week or so. A post written in the guise of TF2's announcer on the TF2 blog announces that three "absolutely unique one-of-a-kind hats" have been added to TF2. They won't go on sale in the Mann Co store, though. One of each will be awarded every day to the player that gives the most gifts, wins the most duels, and buys the most map stamps during that 24 hour period.
Tying rewards to map stamps is quite a nice move. Each stamp corresponds to a community made arena and all proceeds from stamp sales go to that map's creator. The investment needed to take the duelling hat is harder to justify. You need to buy an item to initiate duels in TF2. The cheaper way is to incite others to duel you and then win, sidestepping the item cost and earning an additional tick towards hat victory. The hat earned for giving gifts could prompt some players to clear out old items they've been hoarding in their backpacks, which will hopefully result in lots of apparently random acts of generosity.
"LET ME GIVE YOU FREE STUFF!" "GIVE ME FREE STUFF!" and "DUEL ME YOU COWARDS!" may become standard battle cries in the TF2 in the days to come. As the madness unfolds, you'll be able to track stats like headshots and gib shots using Strange Parts, which can now be found in crates. These can by used with Strange Weapons to keep track of your actions. "Strange Parts are still a work in progress," says the blog. "So if the mood takes you, visit the TF2 forum and let him know what you're interested in tracking."
