Some guy named Hutch got hands on time with Call of Duty Black Ops multiplayer. He was kind enough to upload some youtubes with his impressions and observations via voice over commentary. From what he says, it seems like Treyarch has attempted to keep the game a little more balanced than Modern Warfare 2. Shotguns aren't overpowered, damage increasing/mitigating perks (juggernaut, stopping power) are gone, and in Hutch's own words, you need some skill to get kills. Nice.
Aside from the Team Deathmatch, Hutch shows us Wager Mode, in which you have only your primary and melee, no perks, secondaries, or grenades. You start off with a pistol, and for each kill you score, you level up and instantly change weapons. The winner is the first one to get a kill with all 20 weapons in the mode, the last being the fucking sweet ballistic knife. Looks like fun. Also, a quick peek at class creation.
These are definitely worth watching if you're a CoD fan. While the maps look too much like Modern Warfare 2 (I want to see a jungle map) Hutch says the game plays more like Call of Duty 2, which I've never played, but he made sound like a good thing.
Updated with the official Wager Game trailer, which details the different modes that make up the Wager Game as a whole. Looks awesome, I have a feeling this may be my game mode of choice.
Videos are after the break.
