Everyone could easily remove all trees, bushes, buildings, roads etc. from the game just by cut the files out of the "Addons" folder.
- Legacy ID
Locate your "DayZ" folder. S:\Steam\SteamApps\common\DayZ
Go into the "Addons" folder : S:\Steam\SteamApps\common\DayZ\Addons
And then remove the desired files (for example - plants2_bush.pbo).
After that you can just join a game normally and play without trees, bushes etc.
