Robert Bowling (402) has done another question and answer on his Twitter page. Please note that there were a lot and I took game related tweets and added it here:
@fourzerotwo Is the "Game Winning Kill" only in special ops or all mp games cause that would be amazing!!
@RUCDangermouse "Game Winning Kill" is in Multiplayer. Not Spec Ops. It's just one of many things we do to "make you famous" for sweet kills
@fourzerotwo I've noticed at the end of a game there is a slow-mo killcam, could you tell us if the kill cam relates to us or a certain kill
@seve515 That's the "Game Winning Kill". It shows the last kill in slow motion along with the Callsign of who got it to every1 ingame. #MW2 <!--more-->
@fourzerotwo Sorry if you saw my question and am being annoying, I just want to know if there is going to be a snow theme map for MP on #MW2
@HawtKnight Yes. There are snow maps in #MW2 multiplayer.
@fourzerotwo:>> Can you please tell us what ASSAULT Riffle you unlock at level 28? Thanks :)
@lrpsquadprince Can't. We're only talking about stuff below lvl 27.
@fourzerotwo can you get all 69 stars in spec ops with out having to play it on vet?
@EFE_Assassin No. You have to beat them on Veteran to get all 69 Stars. You get the 3rd star on each level by beating on Veteran.
@fourzerotwo Would you recommend playing Story mode-single player first in MW2 or just go straight into Multiplayer-online?
@JUA1V I always recommend playing the Story Campaign of games first. Especially in #MW2 - we've put a lot of focus on the story of the game.
@fourzerotwo You guys are doing everything bigger and badder. Does prestige go further than 10 this time around? If so how far?
@Nameless105 Can't give any details on Prestige Mode. We're keeping all of that under wraps for the player to figure out.
@fourzerotwo #mw2 if u r holding the laptop for the AC130, can u die while ur on the ground and the AC130 KS will end?
@chrisxchaos37 You can be killed when controlling a killstreak in the air, but your killstreak won't end. You'll finish it then respawn.
@fourzerotwo how is the remake of the original COD coming along? Will it support achievments/trophies too?
@SpearrOAU Yeah. Call of Duty: Classic on XBLA and PSN will have Achievements and Trophies. Multiplayer as well.
@fourzerotwo will it be possible to knifesnipe? I know gravity affects knife path but if u calculate it precisely?? Lol answear mate
@Mdusiek Not possible. You can only throw it so far.
@fourzerotwo Are Killstreaks customizable PER EACH class or do you only have ONE set for all classes?
@SplitHeavens You customize your killstreaks independently of your create a class. So your killstreaks apply to ALL your classes. #MW2
@fourzerotwo Do pro versions of perks keep the non pro effect?
@Clgman666 Yeah. If you have a Pro version of the perk you get the new ability plus the previous ability. It's an addition not a replacement
@fourzerotwo Thanks. I'm looking forward to some Riot Shield, I like defense. But I'm worried once I'm alone I'll be weak, slow, weaponless.
@ShadowXOR You still have a secondary weapon, so you're not completely defenseless. At a disadvantage, possibly, but a good player can cope.
@fourzerotwo if you and your teammate get downed can u crawl to each other and revive eachother before you bleed out? Or is the mission over
@CONVOY52 No. If both players are down then that means mission failure. RE: Can you revive someone if you're down in #MW2 Spec Ops?
@fourzerotwo Seems like none of this new stuff will benefit HC S&D like death/long kill streaks, tactical insertion, etc., anything for us?
@ShadowXOR Riot Shield, Heartbeat Sensor, (silent & reclaimable) throwing knives, Lightweight & Commando perks. All HC S&D favorites of mine
@fourzerotwo Please answer Robert! If i get the Italian vers. of #MW2 will i be able to listen to the English voice-acting? Couldn't in MW1.
@qwerty_LDT No. Each region has a localized version of #MW2 for their region & in their language. Which includes only their language.
@fourzerotwo Are the in game leaderboards more in depth this time around?
@mlgsnipes There have been some improvements.
@fourzerotwo do you need to prestige to unlock more kill-streak rewards in #MW2?
@NateSpeer No. Killstreaks are unlocked through normal progression unlocks through the 70 ranks.
@fourzerotwo Just so you know, there ANOTHER chain mail going around PSN that sez that if you send x messages you get a beta. Debunk please?
@oneshotfinch I can make this easier. ALL PSN chain messages are false. Past, present, and future chain messages included.
@fourzerotwo When designing the weps for MW2 did you do Ballistics tests? Are the weps in-game refleted on that?
@kraven911 Every weapon has a ballistics profile that determines how much it will penetrate an object, depending on that objects density.
@Mainfold8nine Perks don't apply to equipment. Unless it's specifically for one. Also, Throwing knives are deadly without stopping power
@fourzerotwo dumb question, but are there still helicopters at 7 kills and airstrikes at 5 kills?
@DTTCyrax Yeah, you can still go with the classics, but there are lots of others to choose from now.
@fourzerotwo How does the throwing knife work?
@Scorp96 It's a knife. That you throw. Has a slight arc to it, so takes skill to aim properly. If you miss, it'll stick & can be picked up.
@fourzerotwo do all perks have pro upgrades???
@Mr_fRuiitY Yeah. Every perk has a Pro version. Which essentially doubles the amount of abilities available as each has its unique benefit.
@fourzerotwo Has the issue of hosts quitting games just as they're about to lose been addressed. Its a serious problem on the PS3.
@ZR0Ver2 Yeah. We have in-game Host Migration in #MW2 now, so even if a host leaves, the game resumes exactly where it left off.
@fourzerotwo mw2 needs more eviroment interaction that mw1 lacked, can this be expected? (like, shooting steam pipes to make a smoke screen)
@R0DSTER It does. In #MW2 - there is a lot of environmental reaction to a fire fight. You can see quite a bit of that in the MP vids we did.
@fourzerotwo Can you now give us a final number of maps that will be in Multiplayer?
@Evil_Paladin nah. I can never confirm exact numbers, exact playlists (for the most part) or things like that. Want to keep surprises high.
@fourzerotwo are there any new maps exclusive to specops or are they all based on single player maps ?
@Miles_08 Yeah. There are locations in Spec Ops that you can only play in Spec Ops. Each mode is unique in #MW2 but also shares some element
@fourzerotwo do you have to equip a certain grenade so it is able to stick to the enemy?
@iMakin You an customize your 'Equipment' now. So you'd have to give up a standard frag for a semtex, or a throwing knife, or tact insert.
@omfgitstwittter No. At least 1 deathstreak is unlocked when you first get the game, and you'll unlock more as you rank up.
Well, that was a lot of new information! I have a lot of comments on some of it, but share your thoughts!
One thought I had; when going through everyones tweets to get the questions, many of these people are throwing hundreds of questions at 402. I hope he has a filtering service for his tweets
