God Quarry joins Marvel Rivals as a Domination map on September 24 at 09:00 UTC. The September 23 patch announcement gives it a dedicated Quick Match queue until September 29 at 08:59 UTC.

The developer says the update requires no server downtime. The September 29 deadline applies to that dedicated queue; the notice does not describe it as a removal date for the map itself.

Galacta's Gift has a longer window

Galacta's Gift Volume 3 begins with the same update. Its Costume Coin and exchange store run through November 13 at 09:00 UTC.

If learning God Quarry is your priority, use the dedicated queue during its opening window. The gift event remains available well after that focused map queue ends.
