"The event lasts 8 weeks, and starts on week 1 wih a bunch of palm trees and props around the backyard with a huge taco ontop town hall.
On week 2 youll have a telescope spawned in each base named "Talk-o", which shows the leaked rewards system.
Meanwhile, the taco-covered town hall holds new mixed modes, some of which i remember is snack attack. Which is turf that makes you carry trays of snacks, and when you reach the enemy base you capture a 1/6th of the capture progress. If you are in the base without a snack tray nothing happens
Another event is Ice Cream Rain, which has ice cream cones littered around a TV map that gives one of 3 things: Low gravity, Damage boost, or super crazy health regen rate (different buffs can be on at the same time)
Another called "Dairy Disaster" is turf takeover but when the capture point is taken a bunch of cheese drops from it giving buffs
One im excited for: "Devious Cheese" and its accompanying description is "One-Sided Gnome Bomb. Neutral Gnomes Attack Both Teams”
One of the last i remember off the top of my head is "Taco Panic", and its description is "Two teams compete to capture a single taco"
on the final 8th week theres a button that spawns in the backyard that when pressed, starts a cutscene where the taco blows up.
So we actually know quite a bit about this event. The only thing in the air is the rewards from the event. I have searched every texture in the UI/ folder and the only textures that relate to the rewards ui widget are the lock symbols, so the textures must be retrieved from the server then."
