Dennaton Games has started taking orders for a physical box set of Hotline Miami 1 and 2, but the company remains adamant that Wrong Number is the last call for Jacket and Richter.
There are some new elements of course, but where I expected a build on the previous game's mechanics into a brand new experience instead became the same basic feel in a different scenario. Hotline Miami 2 indeed has the Wrong Number in its title, it should read 1.5.
