Great sand vipers coiled around, killing game? (5,8)
I believe the answer is:
space invaders
'killing game?' is the definition.
'space invaders' can be an answer for 'game?' (Space Invaders is a video game). I am unsure of the 'killing' bit.
'great sand vipers coiled around' is the wordplay.
'great' becomes 'ace' (both can mean a talented person).
'coiled' indicates anagramming the letters (letters coiled up).
'around' is an insertion indicator.
'sand'+'vipers'='sandvipers'
'sandvipers' anagrammed gives 'spinvaders'.
'ace' placed inside 'spinvaders' is 'SPACE INVADERS'.
Can you help me to learn more?
(Other definitions for space invaders that I've seen before include "Early electronic game" , "They'll leave you little room" , "Early arcade game -- aliens?" , "Early computer game" .)
