Slapdash Invitation is a Note in Deathloop .
Location
Found taped to the Vanya's Restaurant door and Anatoly's Apartment door on the lower level of Karl's Bay in the Morning. If the Pact of Smoke was tampered with in Updaam in the Morning and Vanya survives, it will be on a table inside her Restaurant during the Afternoon and Evening. If Anatoly survives, then it will be in his Home during Afternoon and Evening.
Transcript
Hey nerd,
Come up to my place in Updaam around noon and see what Brotsky in AEON engineering cooked up for us. It's the perfect way to spend First Day, if you know what I mean. (That's rhetorical. I know you know what I mean, I think.)
See you soon!
