Just like real life, you need to eat, drink, and use the "water closet" (WC) - aka the loo, the toilet, the potty! This means finding food, hydration, and of much less importance (seemingly none at all actually), take a whizz.

Food is found in tin cans and occasional strange burgers. You can find these at gas stations, motels, and sometimes on the ground of other Points of Interest. The majority of what you find will be canned goods, but sometimes you can find a burger either on the fence of a garage or in the freezer of a gas station.

For hydration, you have two options: soda cans, and containers of water. Soda Cans are found in freezers, on shelves, on the ground, almost anywhere, and are probably the most improtant of consumables in the game. If you run out of water, you lose health until you die from dehydration. If you can't find soda cans, an alternative source are containers of water. Generally these are blue plastic jugs and drums, but you can also fill jerry cans and gas cans with water and use those as well in lieu of the regular water bottles. Just be careful to empty out those other options in their entirety before filling them. Radiators work too (though I wouldn't do that in the real life). To drink from canisters/bottles/radiators....pick up the item, scale the item up close, and get the cap inline with your cursor, then right click to open.

Going to the bathroom however, optional, there are some achievements (some are pretty gross), that involve this function. I think it's more here for comedy, and to make the toilets and urinals in the game have a purpose simlar to Postal 2.

But you also don't just need to take care of you, you need to take care of your car too. Your car requires fuel, water, and oil to run, and it also requires tire changes periodically (though there's options to turn the usage of these consumables off if you'd prefer, but it makes the game a little TOO easy.

First off is Diesel or Petrol. Diesel runs the IFA and Poyopa engines, while the rest of the cars use Petrol (Gasoline). Fuel is usually found either at gas stations in the pumps (obviously, and in the most capacious amounts BTW), big 50 gallon metal drums, smaller 75 metal drums (blue), green jerry cans, and red gas cans. You can also use the "transfer" feature (using the scroll wheel on your mouse) to transfer fuel to containers for putting in your own car. Total scavenger stuff.

Next, all vehicles use oil. Oil is most often found in the gas cans and jerry cans on it's lonesome. Oil is put into the engine by opening the cap and then putting the (open or closed works) container over the area the cap covers.

Water is put in the radiator, and works the same as oil but with the radiator as I said. It's found in large containers at Cow Pastures, behind your house, gas stations, and can be found in large blue plastic drums, and smaller blue plastic containers, as well as Radiators from other cars.

Body/Chassis - this is what you start with. Initially, this will just be the "Dada" car, but as you unlock more vehicles by completing them, you can start with all the other vehicles (see next section for these). This is what determines what vehicle you are rebuilding, and you build off of that. Remember, if parts match your chassis, the "help" highlights (if enabled) will show GREEN and if it's the wrong part they will be YELLOW. Don't let that discourage you from being creative with cars.

Seatbelt Parts - All Bodies/chassis come with seatbelts already preinstalled , buckle and the clip. It's suggested to use these, especially in faster or more cantankerous vehicles like the Golf or the Poyopa pickup truck.

Sun Visors - Some of the vehicles have these, The Golf and UAZ van come to mind.

Wheels/Tires - All vehicles have wheels, and tires that can be separated. The UAZ and Dada also have hubcaps on their wheels that are separate parts. However, hubcaps are pretty much always attached to the rims already.

Engine - The engine is one of the most important parts obviously. You need to pay attention to fuel type. The IFA and pickup truck are Diesel, the rest are "Petrol" (gasoline, Europeans/Africans call it "Petrol"). ALL engines require varying amounts of engine oil to work.

Radiator - The Radiator keeps the engine cool and is filled with water, ALL radiators REQUIRE water to work, or then your engine starts overheating and depleting oil.

Battery - The Battery is required to start the engine. They come in three amperages: 50 (Lada, Musgoat, Poyopa, Golf...), 75 (bomphiac, Van, Tucker), or 180 (IFA truck). Failing to meet the minimum will cause your vehicle to fail to crank.

Horn - Horn is obvious. It's not a required part to drive the car, but is required for a completed build.

Pedals - There are always three pedals, some cars have the same three (Musgoat, Dada), while others can have two styles (Poyopa, Tucker, IFA, UAZ), or even three (GTR, Golf, Bomphiac) variations matched to a specific function.

Steering Wheel - Steering wheel is required for making your car completley drivable. It's also important to mention that this is an influencer on the handling of the vehicle. Typically, it seems larger wheels and the Ship Captians wheel (custom part) allow for more control, while the smaller wheels make for faster turning.

Shifter - needed to change gears. Without it, the car won't be able to reverse, and will be stuck in 1st gear, which means slow movement forward and a screaming engine (and high fuel consumption IIRC).

Seats - You need at least one to drive and up to seven to complete a vehicle (IFA).

Radio - Required to complete a vehicle, and also something you will want if you want to listen to the in-game soundtrack while you drive.

Dome Lights - Most cars have one, the majority use the same one from the Dada which is also used for trunk/hood lights.

headlights - Needed to see at night or in inclement weather, and to complete the car. Most have only two, at least one (Bomphiac) has four. Activated using the "L" key.

Taillights - needed to complete a car, are on full time when the headlights are on.

Front/rear Turn Signal Indicators - some cars have these separate, like the Dada, Bomphiac, GTR, etc.
