Play with Hardcore, who came with the latest update. We are not perfectly sure how this mystery character can be unlocked. It's likely that you have to kill the BBQ Grill Boss at the end of a shoot skies "level". Maybe there is a second condition needed. Please tell us about your experience with the unlock! Thx to everyone who helped with suggestions (Steffi, CK1, gadger, Rhino, Ken Ash...)!
Play as the Yeti. The Yeti is an old Shooty Skies character, that was already in the game befor the Munchable Madness Update came out. During playing a wooden box will occur with a popsicle inside. Collect the popsicle to unlock the secret character Popsicle, P.I.
We unlocked this secret character with Hardcore, but it also reported that this mystery character can be unlocked with other new Characters from the Munchable Madness Update (Cutie Pie, Hardcore, Jabba The Hot, Sweet Beets, Lil' Softie, Tootnramen or Great Shakers). Die at a score of exactly 10 to unlock this secret character.
It looks like this mystery character can be unlocked with any of the new Characters from the Munchable Madness Update (Cutie Pie, Hardcore, Jabba The Hot, Sweet Beets, Lil' Softie, Tootnramen or Great Shakers). We are not perfectly sure whats the exact unlike conditions. Probably you have to kill a certain enemy like the toaster. Nevertheless it doesn't seem to be too difficult, just play a little bit.
Most probably you have to play with Jabba The Hot and perform round about 6 charged attacks (do not press the screen for some time to charge your weapon). Jabba The Hot looks quite similar to the secret character Insanity Pepper so this method for unlocking him sounds reasonable.
Play as Lil' Softie (or Hardcore, Jaba The Hot...) and collect the boxes with the ginger breads inside. You will need round about 20-30 ginger breads to unlock the new Shooty Skies Secret Character Ginger.
Another new secret character from the Lunar New Year Update is Ya Zi. To unlock the red dragon YA ZI, shoot down 88 wooden boxes and collect 88 the red envelopes inside. Once you collected enough red envelopes Ya Zi will be unlocked. Red envelopes are a typical present for children for Chinese New Year. Usually there is money inside.
The Monkey King is one of 2 new secret characters in the Chinese New Year update. To unlock the Monkey King play the new character Red Monkey in Ball Challange Mode. This is a new mode that was added with this Update. Shoot down round about 15 wooden boxes with Red Monkey and collect the small golden monkeys inside. Once you collected enough golden monkey you will unlock Monkey King. By the way: 2016 is the chinese year of the monkey.
The last secret character of the Shooty Skies Christmas Update was a big mystery. Until the 25th of December neither the name, nor the design of this character was known. This is because this character could not yet be unlocked in game. The developers gave a hint on twitter how to unlock it: You have to collect the daily reward every day 12 days long. If you started doing so on the day the update was released (Dec 14th) the Secret Character would have been unlocked on Dec 25th as a christmas present.
Of course Yuley can still be unlocked by collecting the daily reward 12 days in a row.
This character is a tribute to the American thrash metal band from California with the similar name Slayer. To unlock Sleigher choose one of the new Christmas Characters (Shooty Feet, Elfabear, Blitzen, Ho-Ho-Hobot, Hoppy Holiday, Poley) and defeat every Christmas enemy occurring in one round including the Christmas Boss.
It may also be possible that you need to beat round about 3 christmas bosses in different rounds.
