Because everyone begged them to release it early so they rushed development too much, cut off their community, and didn't have a big enough or long enough beta.
@TiSe88 Get all 3 kills with Blunderbuss, get the bonusses ´Looper´, ´Homeward Bound´ and Headshot, that´ll give you 41/44 points per kill, with ´Assassin´ instead of ´Headshot´ you get 56 points.
PS. those are the points I got, they might be different.
The Ghost level is utter garbage. Way to make a flash game unnecessarily annoying because of poor control and OP enemies that have a huge lead on brain dead AI partners.
The terminator level is a pain, it personally took me over 50 tries to get it, with multiple tries ending just 4 short, as you said. But you'll get it in time!
