I was in the outpost with my lvl warrior for like 5 weeks ago. Then i saw a guy that shouted:
RUN FOR YOURE LIVES!!
And i didnt get something so i stayed in outpost.
Then he shouted again: RUN FOR YOURE LIVES!! OR YOU DIE
Then i saw him and like 40 gobs 10 pugs and 10 flys and many many more things! I was like OMFG im gonna die but they didnt aggro me :D phew
