To keep the server running smoothly, these rules apply (values are the current server settings):
Build limits: per base at most 12 turrets (auto turret, flame turret and shotgun trap combined), 60 lights, 100 storage boxes and 40 planters. Per player or for the whole team combined: 40 / 150 / 250 / 100. Existing items stay – you just can't place new ones beyond the limit. Note: Rust itself disables auto turrets when more than 12 are within 40 m.
Abandoned bases: normal upkeep applies – as long as the tool cupboard has enough resources, nothing decays.
Vehicles: minicopter, scrap & other helis, boats & submarines, cars & bikes are removed when they have been unused for 12 hours in a row, unlocked, outside any TC range and with no player within 300 m. Tip: lock your vehicle or park it within your tool cupboard range.
Dropped items: Stones, Wood, Cloth, Animal Fat, Bone Fragments, Charcoal, Leather, Empty Can Of Beans, Empty Tuna Can, Plant Fiber on the ground disappear after 120 seconds – everything else after Rust's usual time.
Animals & scientists: with 2 or fewer players online they respawn a little slower; scientists at custom spawn points only appear when someone is nearby.
Commands: more than 5 chat commands within 10 seconds are briefly throttled – just wait a moment.
