Fun but problematic

A couple things after 72+ hours of gameplay i have to say it has promise but isnt there yet they really need to improve vehicle mechanics in this game i dont think people should be able to siphon gas from your bike while you are riding it then shoot you if your in pvp and camp you if your in pve (trust me i know had it happen in both) so i think they should have a siphoning tube that is a 1 time use that cant be used on moving cars so that gas isnt spammed and people can still feel like bandits too win win another thing if your going to save up coins and badges for these vehicles people shouldnt be able to hop on your bike at anytime and take off i understand if you just leave it in the open but its gotten to the point where i just leave it at home because i dont want me and my friends to babysit the bike while we raid so i suggest a raidable key system if you have the key you can turn on and off the bike it only works on your vehicle and if it is stolen from your chest or looted off your corps it is useable but otherwise people cant just magically have your bike some, also some of the zombies will fade out of existence and then while you are exploring they will randomly pop up in your face scary as heck yes but unless the developers intended for spooky floor glitching casper zombies that needs fixed too thank you

Bugs sooooo many bugs and hackers

Was playing this game it was fun and all until I started to notice that because of ping people can kill u behind the wall etc. But this is understandable, what is not understandable is why can’t I build walls in my house? I get this problem when I try to build a wall and it says too close to another object even though there was a wall before that I deleted and tried to replace. The 3rd problem is that you can get trapped by people in their build, it’s not like they build a box around you but some people managed to trap someone in the base platform (inside of the base platform) which obviously should not happen and should be fixed. Another problem is that you get unbalanced xp earning, you get 100 xp for destroying a tree which takes about 5 hits and the same amount from a barrel which takes 2 hits, in my opinion you should lower the cost earnings from a barrel. ANOTHER problem is that sometimes if you pass through the door and it closes behind you, you will be send back to the side of the door you came from. ANOTHER problem IS you can see through walls if you move your camera just the right way. ANOTHER problem is HAKERS, I personally just found only one hacker but it’s still a big problem , please add a way to report people in the game. Another problem is that sometimes you can get stuck and will not be able to move for no reason at all.

Great Game

Me and my friends enjoy this game very much because we don’t have pc and this game reminds us of rust the graphics and gameplay is smooth a lil point but that’s ok.
There is few problems that needs handling like the steering of the car if u go a certain speed the car will start fishtailing for no reason also there should be a flip function or push for vehicles that get stuck like boats to close to land. Also some zombies and wolves can hit u and u not even close, another matter is like everyone says the structure placement needs work we can’t build wat we want sometimes when we demolish stuff. And lastly but not least the most important thing that needs fixing is trapping it’s a great game but there’s been people getting trapped in foundations by others on pve and it’s really annoying a lot of players have come and gone because of that reason alone. One more mybad can we please get voice chat everyone wants so please the chat has no filter so people say wat the want anyway so can we please get voice chat
