The (RED) Creator Cup was a charity broadcast to raise money for COVID-19 relief efforts via (RED), a renowned global charity. Minecraft content creators worked together to defend a village from hordes of enemy monsters, with modifications to the game occurring via donation incentives (donate $X, and it has Y impact in the game).
It was a collaboration between Dexerto, (RED) and Unsigned, and you can read more about the project in Dexerto's article
