As in, what modes do you want? Do you want never ending killstreaks? Do you want hundreds of players in a single (Huge) map? Online map making groups? As in, you can make a mpa with multiple people

i thik the MP is like the Killzone 2 huge maps with vehicel and destructable world(not the destuction like BC2) i think it'll awasom

i think a destruction like in bad company 2 would be nice and something like the squad deathmatch from bad company 2.

How about a 100+ player free for all!!!! Insane, yet fun. Even though your number of deaths would skyrocket

hopefully it will be done well.

the only thing I really want to see changed is to get rid of the lag, crysis is the only game I play that seems to have terrible lag. everyone seems to be jumping from place to place constantly. I would prefer a method similar to the source engine, (which seems to handle lag very well, while not being unfair).

Something like crysis wars

I would love a more advanced destruction system than Bad Company 2, While BC2 does have it, it looks like puzzle pieces and it is TERRIBLY optimized for Dual Core processors. I get 15 - 25 fps in Bad Company 2 on medium simply because i have a Dual Core E6750. If Crysis 2 can enhance on what they already have implemented for the singleplayer, and get it to function correctly in the multiplayer, this will easily be a GOTY.

I would also like some more team based gamemodes, like Capture the Flag and Domination. Of course if Crytek can come up with another great gamemode like they have in the past (Power Struggle, Assault) i would absolutely love it.

As for killstreaks, i say a big fat no to them. They encourage camping, cheap gameplay that only benefits yourself and not the team. From playing the Medal of Honor Beta, i know this for a fact. When i go for those killstreaks i tend to become totally self centered and i will sit at a distance and pick people off, which has no benefit to my team whatsoever. The currency system that Crysis Wars currently has works perfectly. You get points for team based objectives and not just getting kills, and you can spend this currency on whatever you want. If you get 200P, you can either get a SCAR with a laser sight, 3 grenades, 2 claymores, an Anti Aircraft Tank, FY71, Precision Rifle (without scope), the choices for your own reward is endless and you have complete control over what playstyle you want to reward yourself with, and you think about how you can give that tactical edge to your team. Killstreaks are not the way to go, however the currency system we already have works just like a charm.

As for the server slots, I am fine with whatever Crytek chooses as long as it is a 8on8 or higher. I dont feel that having hundreds of players on one server is the way to go yet, because the technology to successfully support that just isnt there. Yeah, MAG did manage to get 128on128 in a single server, but they sacrificed graphics, gameplay, and content just to get that number. Maybe a decade from now the technology will exist where servers and clients can support 256 connections and have great graphics and gameplay, but today the technology simply does not exist. Smaller, tactical maps with 16 - 32 players is just fine.

I would prefer a multiplayer like Crysis Wars. I love the currency system, no killstreaks, the maps, and the server size is just right at 32.

As long as they put in some sort of classic mode for Power Struggle then they can do whatever they want.

Now I can argue and many will agree that my opinion isn't based on a fear of change this time, just a fear of consolization.
