My problem with it is it doesn't do anything better than MW2, and does many things worse.
I realize as a military historian I probably care about little details more than the average person, but to me it's game-breaking when Treyarch shows off their utter ignorance of weapons in COD Black Ops.
Another poster has already listed them, but I'll touch the high points:
- The vast majority of available weapons in the game were *not* available during the time period the game supposedly occupies. Indeed, a number of the weapons didn't come out until the 1980's, for a game which has the last single player op in the 1960's. We can argue until the cows come home about 'prototypes' or Black Ops getting them much earlier than the production date, but it's too much.
- Actual, existing weapons of the time period were ignored almost entirely. I don't know if Treyarch wanted to avoid any weapons already in MW2, but they ignored dozens of weapons from the time period in favor of things which, to me, made no sense.
Example: the Thumper, the single-shot break-open Grenade launcher, was in heavy use during Viet Nam, but is ignored (except for the 'China Lake', which I won't even comment on due to how ridiculous a pump-action 40mm grenade launcher is.)
I could understand if the time period had few weapons to choose from- but it didn't. It came across as the makers of the game simultaneously trying to avoid MW2 weapons but at the same time trying to pick weapons that 'looked cool' without regard to how effective those weapons actually were.
Case in point: the M72 LAW. I have prestiged several times, and to get Ghost Pro I had to wait until level 30 to get the Strela, a two-shot launcher with a lock-on mode. The reason I waited was I *had no idea* they had put a lock-on mode on the LAW...because the very idea is so insane my mind would not process it. The M72 LAW? A disposable, low-powered warhead unguided rocket? And it has an anti-aircraft lock-on mode???
I realize that many people see that and don't even blink...but to me, that's like saying "oh yes, the Chevy Blazer has a 'submarine mode'. What, you didn't know all Chevy Blazers could be sealed and drive around underwater like a nuclear sub?"
