Any easter eggs found?

[BlueFury]

Well, OP was asking for easter eggs, and schmup.exe is an easter egg. Not sure what you mean. It's either an easter egg or it's not.

Yes. Schmup is indeed an easter egg.
TFEF said that one of the bosses in Schmup was a reference to the Penumbra tech demo. (not directly talking about schmup as it is just a regular part of the game)
I just pointed out that Schmup in itself is an easter egg.

Anyway I just remembered another one.I don't really remember a lot about it though, since it was a long time, since I played it.
Anyway there is some kind of terminal where you can activate some kind of security procedure (let's just call it the "Fix emergencies procedure").
It gives you a lot of questions such as "Is it a minor or major emergency (minor being the coffee machine not working, and major being flesh eating zombies)" and "Did you start the emergency?".
When you finally get around to activate it, it states that it cannot activate the "Fix emergencies procedure" since there is currently an emergency going on.

There are also the one with using the frozen down head on yourself. (should say something like "You must be sick.")
You can also use the arm on yourself ("Finally something to scratch my bag with.")

As I said I don't remember a lot about these, since it is a long time since I played.
The last one I haven't even tried. I simply read about it on the forums. (I don't remember who wrote it. Some thread about amnesia I think)

Maybe I should play again..

yeah its an easter egg
any EA's ingame?
