Upgrading is a Game Mechanic that describes the process of improving a Block in order to make it stronger. In order to upgrade a Block, one must have the materials needed for the upgrade in the character inventory and have an appropriate Construction Tool equipped. An upgradeable Block is targeted with the crosshairs, and clicking the right mouse-button will initiate the upgrading process.
There are only a handful of tools that can upgrade blocks, some easier to obtain compared to others.
Both stone axes will upgrade 1/3 every use, requiring three uses to completely upgrade a block. Claw hammer upgrades 1/2 every use, requiring two uses to completely upgrade a block.
The nailgun upgrades blocks instantly with a single use. This, however, means that the player should be very careful when repairing blocks with it as they can be accidentally upgraded to a higher level.
These are the different upgrade materials that could be used during the process.
- Wood is the most basic upgrade material. It is used to upgrade Wood Frames and other wooden blocks, traps and furniture.
- Iron is sometimes used as an upgrade material after wood and when upgrading Iron Frames. The upgrades offer a bit higher durability than wooden blocks.
- Forged Iron is used to upgrade especially furniture, such as doors and different traps.
- Cobblestone Rocks are used to upgrade blocks after wood to Cobblestone Blocks. They offer a lot more durability than wooden blocks making them valuable for defending against the zombies.
- Concrete Mix is used to upgrade cobblestone blocks to Concrete Blocks. After successfully upgrading a block with concrete mix, the player must wait for a certain time for the concrete to dry to upgrade it again.
- Forged Steel is the last resource used to upgrade concrete blocks and other furniture, such as doors and hatches.
This is a table containing the resources needed to upgrade from a craftable block to Steel Blocks. This includes the base cost of the craftable block.
Note: These amounts are for the base crafting, certain perks such as the Advanced Engineering lower the amount of resources needed.
|Scrap Iron Frames||95||4||20||10|
|Wet Concrete Blocks||20||10|
In terms of the most basic resources.
|Scrap Iron Frames||295||24||64|
|Wet Concrete Blocks||200||20||64|
To summarize the tables: Most cost-efficient way of building concrete/steel blocks is through the wet concrete blocks. However, the player has to consider required workstations and crafting time when choosing the block to go with. Upgrading blocks also gives a decent amount of Experience, which should be taken note of as well. Blocks, such as the wet concrete block, also can't be picked up in the event of misplacement and have to be destroyed, whereas frames, such as rebar frames, can be freely picked up after placement.
This upgrade path starts with Flagstone as the base block and ends with steel blocks.
This upgrade path starts with Iron Frames as the base block and ends with steel blocks.
Concrete has two ways of upgrading blocks to steel blocks. The first upgrade path starts with Rebar Frames as the base block and ends with steel blocks.
The second upgrade path starts with Wet Concrete Blocks as the base block and ends with steel blocks.
