At the Start of a Day

Make 5 roleplaying chains:

Roleplaying Chain: Leader's Office
Roleplaying Chain: Infirmary
Roleplaying Chain: Meeting/Common Room
Roleplaying Chain: Front Porch
Roleplaying Chain: Outside Base

Make the defending chain if necessary:

Defending Chain:
Enemy (## health, # fighting skill)

Fighting Scores
Level 0: 0-20
Level 1: 0-30
Level 2: 0-40
Level 3: 0-50
Level 4: 0-60
Level 5: 0-70  

When processing commands, you should have a random number generator tab, game instructions tab, the current day tab, and editing the next day tab all open. Comments to commands are made on the current day tab and changes made by the commands are edited into the next day tab. In general, all edits are made on the next day. I typically decrease the character's energy as a way to make sure people aren't doing more commands than they are allowed to, but this isn't entirely necessary. After closing the day, the energies can be restored.

Check the Seasonal Effects:

Spring: farming can occur again, +1 threat
Summer:
Autumn: +1 food from farming
Winter: 0 food from farming, -1 threat, -1 scavenging    

Dangerous Missions

Scavenging, patrolling, Clearing out areas

Use a random number generator (1-100). Compare the number to the probability of injury on the table (fighting skill is cumulative of the task group). If the generated number is lower than the probability, then run the probability of the type of injury for each task group member. If the generated number is higher than the probability, then the task is successful. Then generate a random number from 1-5. If the number is 5 then increase the player's skill level by 1/4.

If a player is using a ranged weapon, generate a number from 1-threat for the amount of ammunition they use. If the number is higher than on hand then just set to 0.

For patrolling missions, increase the border strength by 1. 
For scavenging missions, see the Collection Missions.

Collection Missions

Use a random number generator (#-#) to generate a number. The generation parameters are based on the range of the number of resources that can be collected at the player's skill level. Each pair of players than do collecting missions together get +1 resource, depending on which resource they are collecting. Then generate a random number from 1-5. If the number is 5 then increase the player's skill level by 1/4.

Scavenging

Level 1: 0-3 food, 0-3 materials
Level 2: 1-3 food, 1-3 materials
Level 3: 1-4 food, 1-4 materials
Level 4: 2-4 food, 2-4 materials, 0-1 medicine
Level 5: 2-5 food, 2-5 materials, 0-2 medicine

Farming (needs farmland)

Level 1: 1-4 food, 0-1 materials
Level 2: 2-4 food, 0-2 materials
Level 3: 2-5 food, 0-3 materials
Level 4: 3-5 food, 1-3 materials
Level 5: 3-6 food, 1-4 materials

Some equipment also gives benefits for resource collection.

Equipment

Hoe (2): +1 food when farming

Scouting Missions

Generate a random number for the building.

1-6 House
7-10 Store
11 Hospital
12 Police station
13 Fire hall
14 Subway station
15-18 Farm

Then generate a random number from 1-4 for proximity.

The building shows up as: Hospital (3)

Reclaiming

Only cleared areas (bold) and buildings that have a proximity of 1 may be reclaimed. Reclaiming causes all other buildings in this direction to have proximity decreased by 1.

Reclaiming also allows for more thorough looting.

House: 5 food, 10 materials
Store: 10 food, 5 materials, 2 baseball bats, 2 spears
Hospital: 20 medicine
Police station: 2 guns, 30 ammo
Fire hall: 3 axes

Farm: 15 food

More on reclaiming later.

The person with the higher score wounds the other person according to their weapon damage and if their opponent has a shield or not.

Injuries can also decrease the energy available for a character. WIP

Training

Training requires one person to be at a higher skill level than the other or a book with a higher skill level than the user.

If training with a person then each usage increases the lower level character's skill by 2/4.

If training with a book then each usage increases the character's skill by 1/4.

Crafting/Building

Crafting/building requires materials and building skill. Builders can begin the crafting/building of an item or a building which immediately takes up the required materials and 1 energy. 

It shows up like this: barrier (1/5)

Buildings under construction show up on the buildings list, but do not confer benefits until they are finished.
Items under construction show up on the inventory list, but cannot be equipped/used until they are finished.

At the End of the Day

Say: --Closed-- in the comments section.

Remove food from the food storage by the number of people in the group. If there is not enough food then randomly choose people who have to go hungry. People who are already hungry are moved to starving (-1 energy). Starving and hungry people are prioritized for eating order.

Add food according to how many greenhouses there are (+1 food/greenhouse).

Decrease the border strength by the number of buildings/2. Increase or decrease the threat level based on the border strength.

Level 0: border at 100% strength
Level 1: border above 90% strength
Level 2: border above 80% strength
Level 3: border above 70% strength
