Vitality, FURIA, NAVI and MOUZ have accepted direct invites to the eight-team competition taking place in September.
StarLadder has announced the four teams directly invited to participate in the StarSeries Fall tournament, a $500,000 competition held on LAN in Europe from September 17-20.
Vitality , FURIA , Natus Vincere and MOUZ will take part in the event, which marks a significant improvement on last year's edition , which only featured one top-20 team in NAVI, who ended up clinching the trophy.
The remaining four teams will come from closed qualifiers in Europe (two spots), North America (one spot) and South America (one spot), which will begin in late July.
StarLadder has yet to announce the host country and city of the event, having only revealed as part of the required additional information that it will be held in a Schengen country.
