-- General ---------------------------------------------------
23 brave souls have ventured into Phobos:
15 of those were killed.
And 2 couldn't handle the stress and committed a stupid suicide.
6 souls destroyed the Mastermind...
1 sacrificed itself for the good of mankind.
3 killed the bitch and survived.
2 showed that it can outsmart hell itself.

Just my luck, last time I found the GCB was in 0.9.9.4 and then I ran out of bullets.
And to make things worse, this time I actually found the gun before Cybie so I could have used that to finish Cybie off but I thought the requirement had been changed to killing Mastermind already...
