Mechwarrior Online, the ailing, but yet still interesting MOBA in the Battletech universe is having a Corona-chan gift. Free custom mech, premium time, and a mech bay. Amusingly the free mech is green and gold, the colors of House Liao, the China-in-space faction. I don't know if that's intentional or not on the part of the creators.
