SIerra's walkthrough is pretty extensive. Have you read it, Shuffles? It should be in your "Outpost 2 Divided Destiny\Docs" folder.
A LONG. FREAKING. TIME. AGO.
So long in fact, that I forgot it existed.
Mine, of course, would be better.
EDIT: Wow, that Sierra one would be pretty hard to top details-wise. However it is somewhat long winded with lots of scrolling/searching to do, perhaps just a more readable version would be good.
There is however a few additional things I would like to put in mine:
-time-marks of all disasters.
-details about all waves of attackers.
-alternate strategies(or fun stuff you can do)
But still, that guide is pretty complete. I must not read it otherwise it may change how I write mine (if I do)
