There are 4 types of Reward crates players can obtain during a ZM match: Bronze, Silver, Gold and Crytal/Red Crystal. During a ZM match, players can check the scoreboard (Tab key) to see which crates they have owned and which one comes next. Once the points requirement is met, players will receive Reward crates immediately. If players finish/fail the match, they have the option to open the crates right away at the result screen, or save it for later. If players get disconnected / kicked out of the match, they can find the Reward crates in their Item Storage and open them there. Boss tokens can only be acquired by playing at Normal Difficulty.
