Crafting Series — BioShock: The Collection eGuide

Title	Points	Trophy	Description
Basic Inventor	5	Bronze	Successfully invent at least one item. You’ll encounter your first U-Invent machine in the “Arcadia” chapter. Use the various invention components you collected in crates and off of corpses to craft an item available at the machine. You only need to make one item to earn this Trophy and don’t forget that U-Invent machines can be hacked as well, thus lowering the component requirements for each invention.
Avid Inventor	10	Bronze	Successfully invent at least 100 items. The only way to earn this Trophy is to search high and low for the various invention components while playing the game. Search every corpse, open every storage crate, and don’t let a stone go unturned. Of course, even by collecting all of these items, you’re unlikely to earn this Trophy if you don’t spend them wisely. Be sure to always hack the U-Invent machines to lower the requirements. Furthermore, be sure to use the Clever Inventor tonic once you acquire it in “Olympus Heights” to further reduce the component requirements. If you really make an effort to do so, you should be able to unlock this Trophy during the “Point Prometheus” chapter.
Ammo Inventor	25	Bronze	Successfully invent all possible ammo types. Use the U-Invent machines you encounter to create at least one batch of each weapon’s third ammunition type. This includes the Heat-Seeking RPG, Trap Bolt, Electric Gel, Armor-Piercing Auto Rounds, Exploding Buck, and Antipersonnel Pistol Rounds. Collect all of the invention components you can find, so you have enough items in your possession to earn this Trophy during the “Fort Frolic” chapter. The U-Invent machine near the entrance to this area has all of the ammo types listed here.
