Exit the Gungeon’s Hello To Arms update includes Arsenal Mode: a new toggleable game mode in which weapons will be available as loot as well as for purchase in shops. Any number of these weapons can be held in addition to the Blessed gun, and can be used at any time. These additional carried guns have limited ammunition, which can be replenished by finding ammo pickups (exclusively in Arsenal Mode). This mode was designed to be more reminiscent of Enter the Gungeon’s gun management.
