Intravenous 2. There's still time to play Intravenous 1 before the sequel drops. It's like top down Splinter Cell but with more violence (Or at least harder to avoid violence.) and you shoot druggies and degenerates.
TECHNICALLY it's a "third" at this point because he released one of those free "Prologue" things called Intravenous 2 Mercenarism as a 2 mission standalone campaign so you can also play that to whet your appetite
