Crates are special containers that can be opened to win great rewards!
You can find crates in the spawn of each server, which can be teleported to by using /warp crates.
You can preview a crate's potential rewards by left-clicking the crate.
Some crates are not able to be previewed, such as the Mystery Crates.
In order to open a crate, you need to right-click the crate while also having the appropriate key in your possession.
Depending on which server you are on, and on the key itself, the crate key might be virtual instead of physical.
