Alien in Paris (#R)

[K0rn4lsky]

OK I've finally managed to catch the alien that appears in (#Reload online) Paris once in a while. His presence doesn't affect gameplay anyhow. You can encounter him pretty much in every game mode (yes, even in vs online). I'm pretty much sure most of you has already seen him at least once, but I send a picture as a proof

Was this easter egg present in the vanilla GGXX, XBOX version etc.?

I also remember I found a Slash (I assume it was slash because the stage was dark, not sure right now) screenshot with a whole flying saucer flying in the background above the boat (at least what i remember) few years ago.

Anyway, is this just an easter egg without deeper meaning, or does it have to do something with GG storyline? references anyone?
