Engineering Workbook is a book in Prey.
[Excerpt from engineer Clive Lawrence's work journal]
Entry 4: Preliminary tests with an increased spring constant are proving promising, but it's tricky getting fabricators to make them stiff enough but not brittle. Another option is scavenging cargo brought up from earth. Thorstein's assistant has an eagle eye, though.
Entry 4, supplemental: Dear Clive's diary, he's just trying to impress Mary by coming up with an improvement to her toy gun design. Even if he was smart enough to improve on her work, she'd never give him the time of day.
Entry 4, supplemental supplemental: I'm well on my way to figuring out how to increase the range and stay the HELL out my journal Franklin!
