Frequently Asked Questions
How much upkeep does a Rust base cost?expand_more
It depends on size. Rust bills the first 15 building blocks at 10% of build cost per day, the next 50 at 15%, the next 125 at 20% and the rest at 33.3%, then applies the blended rate to the whole base, doors included. How full the tool cupboard is does not change the rate, only how long the stock lasts.
Where do I see my build cost?expand_more
Open your tool cupboard — it lists the resources required and the upkeep drain. Enter those build-cost totals above to get your daily upkeep.
What happens if upkeep runs out?expand_more
Once the tool cupboard is empty, your structures start to decay and will eventually be destroyed. Keep it stocked with the right resources for your building tier.
