OK, the title may be a bit exaggerated. I'm not saying that these are in the same universe-- that is defininitely false! What I am saying is that the artist for OTC may have gotten some inspiration from UG2. The site is going to be shutdown in not too long so I decided to make one last theory. This theory mostly involves Coal Harbor (UG2) & Shipyards/Docks (OTC)
This is from the cutscene "The Docks" in Carbon OTC: (Go to 5:10)
In both Coal Harbor and Docks, there are cranes (which is the main point) -Both have cargo around them -Both have metal beams that span across the road
Beams: Coal Harbor beams can be seen in the video for Coal Harbor In the Docks, there is a beam behind the streetlight
What really makes this theory though, is that they both have rounded/semi-rounded buildings Coal Harbor picture: building is on the top middle OTC: Building is on the far left These buildings I'm comparing also seem to be the same distance from the ground.
Again- I'm not saying that both of theses games are connected. I am just saying that the art director probably got inspiration for the Docks area from Coal Harbor. These are some things to support that.
