The CPL posted the rules of conduct on the CPL Worldtour website. The PK version that will be used is 1.61 with the CPL mod (should be released today).
Players can choose the following maps:
The primary maplist is available for all players to choose from for any match. The secondary maplist is available to be used in conjunction with the primary for all qualifiers. The maps on the secondary maplist may also be used as tiebreakers, and to expand the pool of maps in the primary list as needed.
Secondary maps will not be used at CPL Turkey.
