There's literally nothing in the trailer, but the company does mention that more info is coming April 26th.
Check the teaser here:
Yet another C.O.D. game that will no doubt remain 95% the same as ALL OTHER C.O.D. games but with different maps.
Small repetitive maps, close quarters, respawning on top of others and vice-versa, run and gun style game with little to no intricacy.
C.O.D. needs to take a little bit from Battlefield........though those games are being milled out too and are nothing special nowadays. Bad Company 2 was the last good game they put out.
Although COD has not been good/great since Modern Warfare 2, the current COD Advanced Warfare is by far the worst COD games for so many reasons, I don't want to waist time listing... just google it and Sledgehammer sucks.
I hope this Black Ops 3 version is going to be better, but like the other poster it's typically the same style of maps and things that we love about COD is always taken out (ie. quick scope, all the great stuff from MW2).
Typically Black Ops has been a good series, but we will wait to see how the multiplayer looks as it gets closer to launch date. For now all we are going to hear and see is the campaign mode, which probably 75%+ of us don't care and want to see multiplayer mode.
Not to mention the story mode for this game is getting shorter and shorter. All these game developers are worrying about now is multiplayer, you can't play games with ya friends that are actually in the house with you anymore, now it has to be anti social online gameplay.
