The point is you pay, and you have limited amount of lives. What would this do to the "thrill of the hunt"? How would you feel in combat when your money is on the line? How would you react when you meet the random person? Please note that this is not a thread discussing if they should implement this, Because lets be honest, they probably won't. Let's also assume there are no hackers/cheaters and stuff.

After few years, when all of this zombie apocalypse will be over, some green dudes will attack you for throwing bike into the lake... If it makes you any better, once I managed to pick up bike at the lighthouse between cherno and elektro, the next moment I just rode it into sea, luckily for me there was 2nd bike there :D

Do items on helicopter crash respawn in 10min just like in any other regular spawn points?

I ussualy check around the coast for bycicles, then i go to the NE to berezinho, get alice/coyote backpack on the way, then in berezino i find 2 wheels and fuel tank and head to "klen" it's a hill top NW/e of Khelm / NW of Berezinho. This will give you working ATV+(ussualy a tent), there are 2 ATV spawn points up there. You can always then go back to berezino for fuel/engine parts.

and what if I die?

so as of yet, there is no reliable way to store your equipment? cause I have Dmr, AK, Bizon, m4a1cco don't want to give up any of them, and ofc ammo for all of them, also i managed to bring bike and repaired atv would not like to loose anything

will it happen same with vehicles?

I will assume my tent is in save position, what happens after server restart?

Lets say I want to make some base of operation on some server, have a tent and 2 vehicles, how stable can it be server side, will i just log in and loose every gun i keep in tent? will vehicles despawn?
