First I'd like to make it clear that these cheats were not found by myself,
I saw these posted on the Star Fleet Academy Message Board. The person that
posted them is "TheMan", I do not know who he is nor have I spoken with him,
I also do not know whether or not he personally found them. I have however
verified the following easter eggs. That's all for my disclaimer!
In the beginning of the Balance of Terror mission type "KNAT ATTACK", and
watch out. Simply type KNAT ATTACK, you don't have to press "T" as you would
in a multiplayer game [as you would to self destruct]. Do this before you go
to warp, the Starbase should disappear and several Knats will appear with
the names of the SFA producers.
In the beginning of Common Ground warp directly to Thaxius and scan the life
forms, be careful not to harm them in any way! Lastly in Common Ground, the
first system you search [Hasapur], simply wait around for awhile, some
interesting things will happen [at least two things].
