Kojima Productions got you a little something for your birthday, Big Boss. If you happen to play the developer's latest, Metal Gear Solid 5: The Phantom Pain, on your birthday, you'll get an urgent message that you'll need to return to Mother Base.
What happens next is a fun Easter egg that some players born in August probably won't see for a long time. But it's a nice detail that, if you don't mind spoiling yourself on, is worth watching. Ocelot, Miller and some lesser-known Diamond Dogs sing Big Boss a birthday song — not the birthday song, however, as licensing rights for "Happy Birthday To You" can reportedly run upward of $10,000 — and present him with a cake. Big Boss even gets a real cigar, which he seems to appreciate more than vaping his Phantom Cigar.
Someone else at Mother Base has a birthday surprise for Big Boss, which you can watch in the video below.
We're sure there are plenty more little touches like this — and the hidden radio transmissions referencing P.T. — to be found in The Phantom Pain.
