I'm enjoying it so far. The art is solid overall, but it does appear a bit rushed. It's easy to imagine the artist going "Crap. I need a gun in this scene." Googles gun, uses Uzi as reference.
Now, if it was some sort of colonist, or farmer, it wouldn't bug me at all. Firearms are used for many years in the real world. One of my complaints in the original Aliens adaptation was the lack of pulse rifles and recognizable gear from Aliens. Of course it was because I liked Aliens, but my mind seepms to recall an interview or explanation or something from someone attached that it had been 10 years and of course everything had advanced so we had new weapons. Military gear can stay relevant for many decades. It didn't help the weapons looked pretty generic in that series. I really dug the vehicles overall though.
Its just the UPP appears to be a big rival. I would think they would have been using something designed within a few decades of when the story happens at least.
I skimmed through Prometheus: Life and Death last night and I thought it looked a bit rushed too. There are some noticeable low detail panels where the perspective is only 6-7 feet. Nothing terrible, but noticeable.
