At the beginning of every match, a selection of weapons are chosen to be Rampart's Special Deals. These weapons can only be purchased in Level 4, fully kitted form, with the Splatter Roundshop-up attached if applicable.
Lower-tier versions of these weapons cannot be purchased, but the cost of a Special Deal weapon is 100-200 credits fewer than the cumulative cost of the Level 3 variant.
Sometimes Supply Drop Weapons will be selected, in which case they will become purchasable as-is in the buy menu.
Some matches will have smaller selections of weapons, but rotate selections every three rounds.
