This is Some information about different aspects of the game enjoy and read all of it

Killstreak tweaks

Killstreaks are of course back and more bombastic than ever. Leaked info tells us that along with mechs, turrets and drones are (spoiler alert): EMPs, Hellfire missiles, a controllable helicopter gunner and a whole host of other stuff too. One of the top killstreaks appears to be a drone swarm, which fills the sky and begins dive-bombing enemy players kamikaze-style. Old favourites such as UAVs, exploding remote-controlled cars and attack dogs will also be returning. The Black Ops 2 killstreaks appear to be activated by filling a combat bonus meter in the bottom-right of the screen, making it easier to see how close you are to bringing uber-death to your enemies.

Environmental HUDs

Throughout the trailer, the players inventories can be seen plastered to walls and other scenery. Were unsure yet whether this is just a gimmick for the purpose of the trailer or an actual in-game feature. This could be a way of tweaking your inventory in-game, although Treyarch have said they hope to turn Black Ops 2 into an eSport with a dedicated spectator mode. If so, this would allow spectators to see each players loadout.

Multiple teams

On the scoreboard at the top of the screen we can clearly see that three separate teams are competing. This suggests either multiple-team deathmatches or otherwise special game modes that arent restricted to only two teams per match. The scoreboard and outlandish commentary running over the top of the action also serves to confirm a dedicated spectator mode.

Shock charges

This unfortunate chap is victim of one of Black Ops 2s new toys: a mean-looking projectile that, when thrown, sticks to surfaces and zaps nearby enemies with electricity, stunning them and opening them up to gunfire. At the moment it appears to have similar effects to the flashbangs and concussion grenades from previous CODs. However, the trailer shows it being thrown overhand; with that spike on the end, we wonder if it can be used like an electrified throwing knife.

X-ray scopes

This could be a perk, however in the trailer the effects only seem to work while the player is aiming down the sight, meaning it is more likely an unlockable rifle scope. This attachment allows you to spot enemies through walls and another obstructions, as well as environmental elements like smoke.


Microwave turrets

This deployable turret is called a Guardian. The Guardian emits microwaves that suppresses enemies, which, much like the shock charge, allows you to take them out while they stumble about uncomfortably. If an enemy stays in the microwaves for too long it kills them, presumably cooking them to death.

Mechs

This friendly-looking tyke is called the AGR, a walking, player-controlled tank thats also available as a killstreak, though probably a fair bit higher than the Dragonfire. Also, a couple of well-placed 5.56 rounds are unlikely to take this rascal down. Probably best to run away until you find something with more pop. A ballistic missile perhaps? Or Robocop?

Bigger inventories

The player inventory shown in this screen shows spaces for one primary weapon and one secondary weapon with up to three attachments for each, along with six perks, two types of explosive, as well as three additional slots along the bottom that could be for special tactical perks. Clearly Treyarch are trying to give players a bit more of everything to play with this time around.

Auto-targeting

Another cool weapon attachment that uses a targeting system that bears striking resemblance to Tom Clancys Ghost Recon. The visibility while using it looks fairly restricted, though, meaning its probably best reserved for mid to long-range encounters, rather than close-quarters combat.
