Upgred

"The red bloons have gotten revenge on you for calling them useless! Survive 50 rounds of red bloons with devastating properties."

Upgred is a special mission unlocked at Rank 30. As the description says, it's a 50-round mission with nothing but red bloons. You still start with $650, and you gain regular end-of-round cash, but every now and again the value of a pop will change. Additionally, after you defeat a mini-boss, your money will multiply by 1.25x.
