The system shall be a 1d10, with 1 being epic fail, and 10 being overshot.
Generally no skills will be recorded on a 'level' basis, but exceptional feats may lead to character traits that will influence rolls somewhat.
Wounds will not magically heal in just a few turns, so always avoid any serious injury.
Hunger and thirst are important, but the thing you really want to always watch is exhaustion.
High levels of hunger, thirst, and exhaustion will lead to negative modifiers to rolls, but not immediately to death.
There are plenty of other potential modifiers to your health, so beware
poisons and anything else similarly deadly!
Your mental health is just as important as physical health.
Time is always an important factor, and generally the smaller turns will take 10 minutes of game time (but in reality only about 1-2 minutes) this includes combat.
Otherwise most turns will default to a hour, so plan your actions accordingly, if you want to string a few smaller actions on the longer turns, your character will just complete as many as possible.
Ammo is abstracted, and will run out according to actions and rolls. It is however required to make the gun work, no magical never ending hailstorms of bullets guys
... well maybe a few hah.
The default limit on carrying is-
1 Heavy items
2 medium
6 small
1 heavy=2 mediums
1 medium=3 small
you can always attempt to carry more but will suffer some penalties. Of course backpacks and other carrying peices of equipment can increase this but sometimes come with their own penalties.
This may be updated as the game proceeds, but otherwise always just have fun! (if you want to see a change feel free to recommend it!)
