Blueprints

"Collect blueprints to help Ripley learn how to craft different and improved devices."

- In-game description

Blueprints are technical drawings needed to craft and upgrade Craftable Items.

Summary
There are various blueprints scattered around Sevastopol. They come in three versions, but require Amanda Ripley to have the first version before she can pick up the next version for the same item. It is ideal to at least get version one of all craftable items to make dealing with the Alien and Working Joes "easier."
