Fallout 2 at one point included a survival system, where the player character would have to consume food and water on a regular basis. It has not been implemented and what survives are just abandoned implementation attempts found in eg. the COMMAND.H source file.
Overview[]
Collectively called STOMACH commands, these would track the hunger and thirst levels using a set of simple variables. The max size of the stomach (i.e. max satiation level) would be determined using the following calculation: (100 + (2 * (dude_endurance - 10))). A character with 10 EN would thus have the full 100 point stomach size, while an average EN would have a 90 points size, while each a 1 EN character would have an 82 point stomach size.
The player character would be considered fully fed if the current stomach amount was 95% or higher of the max, and hungry if it was less than 5% of the max amount. The player character would start the game with 75 points worth of food in their belly.
The stomach counter would deplete according to the following calculation: (((1 + dude_has_fast_metabolism) * (game_time - x)) / (ONE_GAME_MINUTE * 3)) Essentially, the game would reduce the counter by one point (two if Fast Metabolism trait was chosen) every three minutes of in-game time.
Meals were divided into six categories:
- Drinks, providing 5 points and including Nuka-Cola, beer, booze, or the water flask.
- Snacks, providing 10 points and including both variants of the iguana-on-a-stick.
- Light meals, providing 25 points and including the box of noodles and the frozen dinner.
- Medium meals, providing 50 points.
- Large meals, providing 75 points.
- Huge meals, providing 90 points.
The system appears to have been abandoned early on. Meals can be ordered at Mom's Diner and Rose's Bed and Breakfast, of varying sizes and types, that would have likely provided stomach points. The ability to order meals is not present in later locations.
