Which CS:GO Weapon Cases are dropping?
Weapon Case drops fall into one of three categories, Prime, Non-Prime and Rare. Any weapon case can be marked as rare. For example, the CS:GO Weapon Case is marked as a rare drop and as such has a very low drop rate. Equally, the most recent weapon case (e.g. CS20 Case) which is exclusive to Prime players can still be dropped to Non-Prime players as a rare weapon case drop.
Prime weapon case drops are available to players who have Prime Status on their CS:GO account. These are typically weapon cases which were introduced recently. Whilst these weapon cases are usually not available to Non-Prime players, they can still be dropped in very rare instances.
Non-Prime weapon case drops are only available to players who do not have Prime Status on their CS:GO account. These are typically weapon cases which were introduced a few years ago. Whilst these weapon cases are usually not available to Prime players, they can still be dropped in very rare instances.
CS:GO Operation Weapon Cases
Operation Weapon Cases are initially only available to operation pass holders throughout the duration of the operation. At the conclusion of the operation these weapon cases are made available as drops to all players. However, the most recent operations Hydra and Shattered Web immediately discontinued these weapon cases at the conclusion of each operation and as such have increased in value due to their increasing rarity.
