DayZ is in some way the daddy of modern survival games and is also responsible for PUBG and those types of games etc. It's also the reason why I have a PC.
It has multiple personalities and people either play it for the survival side of the game, the PVP side of the game, or a mixture of the two, where I sit.
It has all the survival mechanics, the need to find and eat food, drink water, stay warm, base build, catch disease, avoid zombies and then on the other end, find military weapons and fly helicopters 🙂
It's a bit expensive on Steam at the moment but goes on sale a lot so watch out for it!
If you guys get into DayZ that would be pretty cool 🙂
