got this from ufc forum,he play the game at nyc event..

SUBMISSIONS

HOW
Submissions are applied the same exact way as 09. Pressing the R analog.

CHANGED
No more mashing. According to Omar (game developer) submissions are performed by shine method only. Now whats different is you have the ability to do FLASH SUBS (I saw someone using Mir...In half guard he applied a shoulder lock to Carwin...Carwin instantly tapped) which is new. The ability to Submission transition (which varies depending on what fighter you are using) to go from triangle to omaplata to armbar. Which makes it soo deep...You would have to master every single fighter to know who can sub transition into what. To apply this you would press the R analog...Shine counter-clockwise...Press LB (xbox) and R analog...Shine opposite direction...Press LB (xbox) and R analog...Shine counter-clockwise. Each fighter has 1-2 sub transmissions. So this is a HUGE impact on CAF due to the fact...You dont know what sub transition your opponent has...So how will you know to hurry up and reverse your shine? Haha. The final change in submissions are the SPECIAL subs. Everyone knows Joe Stevensons bread and butter is the guillotine right? Well...Fighters have a SPECIAL sub...When they get you in it...Its even MORE difficult to get out. The highest SUB O i seen was Mir with 88 and Nog had 87. The lowest was like 58. STR DOES HAVE AN IMPACT to get out of subs as well. You still apply the Shine method...But your STR factors into it. So brock CAN escape subs. Just not as well as your SUB D 88.

SWAY

HOW
Hold RB (xbox) FLICK L ANALOG any DIRECTION

DETAILS
I found this to be a HUGE factor in ending the fight early. This system is resembles FN4 COUNTER SYSTEM. U sway from a punch...U can immediately strike back for more damage. You can double and triple sway (3 is the most u can do) to avoid a punch. Lean back duck forward uppercut. Lean left lean right left hook. You get the point. When you land...YOU KNOW YOU LANDED. I swayed ALOT. Swaying alone will make you WANT to go toe to toe with your opponent. Honestly making you totally forget that you can kick and takedown. Its THAT exciting exchanging when both of you are swaying trying to be the first to land flush. Unfortunately...Swaying can get u killed...FAST. U can sway head kicks only by leaning back...But all other kicks will land. Sometimes i did soo much swaying i got takin down at will.

LEG KICK AFFECT

HOW
Self explanatory...Keep striking the legs.

EFFECT
Wow...Just wow. They got this one right. NO you cannot check leg kicks. But i used Thiago Alves vs GSP Hardy Paulo etc...When you KNOW the kicks are hurting. The leg kick will make the opponents knee buckle (think rampage vs griffin). Only only did his knee buckle...Get this...His LEG KICK OUTPUT damage was less. His MOVEMENT was slowed (significant difference between no leg dmg vs hurt leg dmg). More % chance of being takin down. Basically if you shoot its guaranteed takedown. The knee turns red (strong side leg...Didnt test the weak side leg).

SIDE STEP

HOW
Same as 09.

CHANGED
No more floating to the middle of the ring with one side step. Actually...When you sidestep its basically taking a big step forward. Heres the difference.

09 Step
HERE-------------------------------------------------HERE

10 Step
HERE...................HERE

Side step jab was out. Instead...Carwin uses a lunging left hook...And a power right straight for his sidestep strikes. You can still RUN the same. But you guys know how people sidestep (or run) back and forward kick or stirke. No more. U sidestep back...you can only throw a strike without reaching. Ala the sidestep body straight punch. U cant reach like that. Its just a standard strike. So basically to land one someone would have to be sidestepping towards you for you to connect.

FLASH KOS

HOW
Self explanatory...Get lucky and land clean.

CHANGED
Well...According to Omar...They were tweaked down...ALOT. But PLAYING the game...If you land clean...And a perfectly timed strike looks like a KO. Trust me. Its a KO. Elbows lean flush...KO. I got ALOT of KOS from swaying a double hooks...Then landing with a uppercut from close range. It was perfectly timed. Every single KO...LOOKS like a KO.

KO MOMENT

HOW
09-Accumulate damage to a persons body part to reach near 100%
10-Omar said it was a secret and couldnt tell

CHANGED
I seen fighters get in KO MOMENT in the FIRST 10 SECONDS. No lie. I was like WTF!?!?! Omar refused to tell us WHY you can get KO MOMENT so early. The KO MOMENTS were the same as 09 so you know what it looks like. Survive and your good to go.

THE MOMENT MODE

HOW
Place a well timed strike to stagger your opponent

DETAILS
I liked this feature. If you land flush...Your opponent will stagger for a maximum of 1.2 seconds. You have to have a FAST reaction to take advantage. You can end a fight in DEVASTATING fashion if your quick enough. When your opponent is staggered you have to input your fighters commands to finish him off. For example...I used Mcsweeney and landed a backfist...It gave me a quick window of where i can input commands...I paused the game and looked what i could do from their...It listed like 4 different methods i could do. So i choose the AB one. He quickly took a fast step forward and threw a 1-2 to drop the opponent. Think of it like an instand knockdown if you can time it well.

CLINCH WORK

CHANGED
You will still use the 09 method of reaching for a single arm collar or MT clinch. But whats different are the transitions from over/under to double under. The animations are wayyy different. Actually omar even said...ALL the animations are different. You will see ALOT more clinches in fights not...Due to the fact you have to MINOR transtion to get from position to position. So if im double over and i want to get to over/under...I minor transition for it instead of pressing forward like in 09. UP and qtr circle for the LEFT arm...DOWN and qtr circle for the right. Same for the MT clinch. I personally asked this question to omar. And he said word for word "Due to undisputedonline.nets rules regarding the MT spam. We took out paralyzing strikes (MT elbows) and flick to swing the opponent around. This time...To swing the opponent...You have to minor transition to where you want him to go as well as press a button to strike. It was easier to block being swung around than have a 25% change to break a swing in MT clinch.
