good question. I think they should go for alleyways and small rooftops for pred. some doors could be open for fireteam to go through buildigs. the more I picture it the more possible i see it actually being done. picture the King Willy death scene, not too tall buildings, the height of trees we have now.
Alleys and streets with a plaza or something for an open space connecting to the slaughterhouse which makes the fireteam automatically cold so they dont have to mud up. they can go in and out to get cold instead. the hanging carcasses can be done, theyve already made hanging people.
or by the time the city map comes out come out with a new FT class which has the silver thermal suits. make it night. make a mission that requires infra red light that pred can see or something.
the rooftops would be the safe travel zone for the pred and the fireteam would have inside buildings which limit preds mobility. there would also be stairways going up to rooftops with the extract there for FT.
there should be a construction site with cranes and shit the predator can get on. maybe even a building under construction. yes definitely adapt predkour to work building ledges,balconies, telephones poles, lights all that, good idea.
