I knew the new game's introduction since a few weeks ago, and I would like to share to you here. :)
Here's the gameplay for the new COD - Call of Duty: Black Ops.
Hmmm, looks like we're going back to the Vietnam War.
The happy thing is Treyarch is the one of the developers of this new version of the COD franchise. Meaning, the animations will be more realistic, of course with the cost of violence. For your information, Treyarch was also the developer of Call of Duty: World At War - the last COD version that documents the Second World War through the eyes of Dimitri of the Red Army (vs. Nazi Germany) and Private Miller of the American Marines (vs. the Japanese Imperial Army).
I hope this time they will include something like the Nazi Zombie rounds in the new game, perhaps a Vietcong Zombie map in the game?
Don't ask me about the weapons, I'm not sure if the game is playing in 2 different eras. Based on the gameplay, the E3 conference only displayed the Vietnam War era. But in this official trailer (below), I can see soldiers using more modern weapons compared to the 1960s. For example, the AK74u, Franchi SPAS-12 shotgun and the Steyr AUG are not used in the Vietnam War as they were introduced in the 1970s.
Can't wait to see this in around 2 months' time. Meanwhile, this is the official trailer. Gosh, nowadays games are like movies.
