Probably someone has already mentioned here, but World War Z was free on Epic Game Store a few weeks ago, and its a good survival game from what I've heard. If you didn't get the game you can probably ask your country's gaming community and someone might give you free keys.
Other then that, if you're looking for a real survival gameplay with other players, I'd suggest RUST. The people in RUST are more toxic than in irl probably, and its tough to get a base started, however once you do that part its really fun to raid other's bases, attacking other players and engaging in 1v1 combat. It has alot of technical things such as security cameras, electricity, farming, horse riding, farming and more.
