Question about Gears 5 UE

While I was explaning what I have inside the Ultimate Edition to my cousin, I told him that I have a code for the characters from « Terminator » and didnt use it. But I can play as both of them in versus. So I got something « special » in my $110 edition that was already in my game!?
TC you got me! I paid for a not-so-much ultimate edition…
