I cant say its bad , its good but more routine and repeating System .. like old gun -> New Gun -> Conflict -> Face Slap -> New Project / Equipment -> Instant Research -> Faceslap -> Ending its weird its cultivating .
From Chapter 4 to 5 there is something Missing and its missing like 40ish years .. from 1950/51 to 80s .. and suddenly Exhibition not Anti Tank launcher but Advanced weapon and there is arab people .. at that time there is serious loophole in story
