Add tkb-48 just because its an exotic bullpup :D
I like bullpups... also, just the fact that there aren't many in game yet. Id like a whole arsenal of bullpups just for variety sake. Like a ks7 or ksg for a shotgun. Practical? Not really. But variety makes games more fun. I guess however a bullpup rifle barrel doesn't stick out as far if youre entering a corner or hiding in one. It wont give you away as much.
Just a silly thought.
