Tribal Pass

You need to finish "big pass" mode.

In this mode, you start with 500 tribesman and 1500 food, and you decide how many (up to 80) of them, and how much food (up to 500) you want to take.

I'm not ENTIRELY sure what you need to do to finish it, by that I mean I don't know if you can fail all your runs and still win.

I got this cheevo by packing 40 tribesman with 1000 food and running through the mode (which is 5 levels, the same as the normal run) and making it to the end.

On the start of the mode, you see how many people have made it to safety (from your last successful normal run), how much food they have and how many days it will last. When I finished first run, I had 59 people there and enough food to last 68 days.
I tried to get another group with 200 food there, and failed.
Tried to get a small group with what food I had left, failed.
Tried to bring 80 people and cannibalize, failed.
Then I just ran with who I had left, killed them off on purpose, and when I had nobody left to make the journey, the mode ended and my achievement popped.


"The flame dew" seems to have 50 days until its reached, so I BELIEVE the point of the story is have enough food to last through it. But again, I'm not quite sure, my run ended when I ran out of people. I would thus appreciate any input from anybody else whose run ends, and why it ended.

Happy hunting (>*_*)>
