Sounds like the river vials from TI6 to me.
They don't care enough about it to even bother lol.
Fun fact: Since your last installation of TF2 or CSS, every spray that a player has used in a game you're in is saved onto your computer. All of them. Warning: sprays may be nsfw.
In the entire time they were active, I never saw one used, ever.
- Limited use item
- Only lasted 15 minutes
- Had an expiration date
- You have to use an item slot and physically walk to the river to use it
Seriously, why even bother adding the feature to paint rivers at all with all those dumb restrictions! When having it work like literally every other map item in the game would have made them so much better as items and a better value.
I can understand not allowing custom graffiti (Although they should for private matches).
I can even understand monetizing it.
But limited uses? Now that's just going above and beyond in greed.
