Hi ianpwilliams.
A lot of new players struggle with early-game strategies because there is a huge learning curve after you learn the controls and start to get into the planning and long-term stages of play.
A good rule of thumb is to always stay unencumbered early on in the game. I always mark a few houses or otherwise safe areas to stash goods in until I am able to go back and get them so that I can run quickly and fight without having to drop items. Combat is really important in the early game, so find guns if you can, but only use them if you are too encumbered to melee or if you are wounded.
If you are having trouble with the cold, try changing the starting season to summer instead of spring. If you want to play legit, try to build fires when you can early in the game, and find some warm clothes asap. Generally, I tend to not pay much attention to the temperature of my character for the first few days. Unless parts of your body are becoming frostbitten, you’ll be okay. Combat is difficult when it is colder, because you will need to wear warm clothes, or fight quickly and put your clothes back on afterwards.
Try to find an easy enemy to train your combat skills with, knife spear is good, makeshift crowbar is good, but my personal favorite early game weapon is the standard pipe (+2 to hit). Baseball bats are amazing if you can find them, and they are easy to upgrade to the almighty nail bat. I tend to keep my eyes open for a black rat for the first few days, because these are the easiest creatures to train with. They will attack you, but they will have a lot of trouble killing you, much less piercing through your clothes, and you can train melee and dodging with them until you get a hit. I usually armor up as much as I can, and then go fight them for a few hours. You won’t hit them with high encumbrance, but that will help you train for longer, and you won’t get damaged too badly from fighting them. Don’t worry about your stamina either, just find a safe place to fight them and melee them until you kill them.
As for mid-game, the most important part of the game past day 1 is finding a working vehicle. I cannot stress how important this is. I generally regard my character in early-game until I have more than one working, armored vehicle, at which point I consider them to be in the mid-game. Farms can be good places to look, but parking lots of mines, sewage treatment plants, and public works are the places I check first. It’s rare to find a working vehicle randomly in a town, but it happens sometimes. Check cars, and if you find a working one, just shove all your stuff in it and drive somewhere safe. A working vehicle instantly takes your player to the next level. You can sleep in them without penalties, store your extra items, and get the hell out of danger very quickly. After this, you want to just kind of roam around collecting items such as fitted armor (clothing), weapons, food, fuel, and books. Books are really important in the mid-game. At this point, you can go back and clean out all of your marked safehouses of their items that you couldn’t carry before you had a vehicle.
