These modules can be used to upgrade ships and other useful equipment.
Upgrade Modules are an upgrade item used to upgrade weapons and a requirement for upgrading ship size.
Upgrade Modules can be found in any chest, but are more common in Challenge Rooms, and also have a 0-10% chance to spawn as a reward when a Reward Bag is used (depending on mission difficulty). Upgrade Modules also have a small chance to drop from most monsters when killed.
