That's what the residents of HeroesLAND call the series of holidays that come at the end of February – "late February festivities." This includes the anniversary of the project's release on February 20th, the glorious Defender of the Fatherland Day on February 23rd, and Maslenitsa week, starting on February 16th.
Traditionally, between each toast during these days, all heroes go to fight various creatures and other wildlife awaiting them in the Vampire Bunkers, Scarecrows, Huts on Chicken Legs, and Houses of Wet Evil.
These expeditions are possible until March 2nd. The Days of Immortality will also last until this date: even if defeated in battles, artifacts will not break, external units will not disappear, and first-level pets will not die.
Happy holidays, dear heroes and heroines. Hooray!
