Carnage in Sinister Six has constantly been getting to take multiple moves. He has been able to make match 3s or 4s two or three times even more in a row before turn ends. Sometimes it is make a match 3 or 4 then do it again before apply ability then make a match 3 or 4 and apply ability again. Is this a bug, glitch, working as intended or other?.
Read. His. Abilities.
[Working as designed. The boss version of Carnage has an ability that grants extra matches when Carnage has enough black AP.]
