2018 OOF World Cup

The 2018 OOF World Cup was the 24th edition of the OOF World Cup, the quadrennial international men's and women's championship contested by the national teams of the member associations of OOF. The tournament took place in Zusea from 1 July to 12 August 2018, and included 16 teams from three continents, with games played across 12 stadiums in 9 cities. The defending World Cup champions were Gran Altiplano, who failed to defend their title. Zusea won the tournament after a 5-3 victory over Meriad in the final.

Accusations of corruption were made regarding Zusea's successful bid to host. While an OOF internal investigation and report published in 2014 cleared Zusea of any wrongdoing, the organization's lead investigator later called the report "utterly incomplete and erroneous." As a result, on 28 May 2016, Meriadnir federal prosecutors opened an investigation into bribery and money-laundering relating to the 2018 host selection process. OOF President August Theodor was quoted as saying that Zusea had used "oily tactics," which elicited a severe rebuke from the Zusian Räich Football Union (RFV). On 20 February 2017, the Zusian Räich Office of Justice announced it would investigate claims of and  relating to the KVF's handling of World Cup construction and advertising. The Redonian government also announced its own investigation.
