All pieces of equipment in Mr Autofire are of certain rarity. The rarer the item, the more powerful it is. You can combine three items of the same type and rarity to create an equivalent item of a higher, more powerful rarity. This is called Fusing.
For example:
- Fuse 3 Common Blasters -> Get 1 Uncommon Blaster
- Fuse 3 Uncommon Blasters -> Get 1 Rare Blaster
- Fuse 3 Rare Blasters -> Get 1 Epic Blaster
...and so on.
The newly-created item will retain the highest level of the items used to create it.
You can access the Fusing feature by tapping on the Fuse button in the Loadout menu.
