Okay so I from what I read I didn't see anything about dual wielding pistols or any melee weapons other than the butt of your rifle and the knife you get with the pistol...
My question here is why set up a teaser trailer with those in it and not put them in the game?

Read my sig all the answers are there.

i expect they were meant to be in, but were cut out due to balancing issues and/or the fact that dual pistols always seem a lot more deadly than any different weapon.

and the dual knives were put in as a cool way of killing the bug.

and believe me, dual knives wouldn't be all that good in game.

Brink seems to have style and substance. Dual knives are probably just style.

But dual knives would be so cool ...oh well life goes on (or should I say gaming goes on? )

It would be cool, but would it be a OHK if you hit with both? bliviongate:

Ching! Ching! *whispers*Die you Bug*whispers*

they were put in to make it more entertaining and intense to watch. its a cinematic, not a gameplay video
