mass effect 3 improve upon the combat of the second game slightly , the graphic of the second game , and drastically improve up weapon selection and customization . combat be get closer and closer to other expert 3rd person shoot like uncharted and Gears of War but still do not feel quite as good . the story and voice acting be top notch although if you playing just the 3rd game and not import a character you miss out on ton of option . you constantly force into the worst possible situation with path selection that would have be avoid if you have build relationship with ally in the previous game . you wont even notice the difference unless you watch someone who have a import character . the previous game help in huge unexpected way with most of the game situation and make ton of minus bonus to remind you of everything you have ever do . so its a great game by itself and as a 3rd part of the trilogy its a amazing game . Multiplayer be similar to Killzones multiplayer with random objective poppp up as you play though . although you only fighting wave of AI enemy with a group of 4 there be no Player verse player multiplayer . you have to capture point , download datum , survive wave , assassinate target , make it to evacuation point the whole time fight wave of random spawning soldier from select enemy type from the main game . you then use money earn for each kill to buy pack that contain random item , alien races\/classes to play as , or weapons\/weapon mod . it be very well do and a requirement for the best outcome in single player . play improve the performance of you troops in single player and be the only way to get a strong enough force for the absolute best end although it may be possible with a import character with every quest do i do not know for sure . I do have to mention performance problem on the PS3 version . some movie sequence be choppy on the PS3 but for the most part the gameplay will be pretty close to constant 30 fp until you in intense fight . some level later on do run a little poor with some room run slightly slower constantly even with no fight kinda remind I of how the PS3 version of Crysis 2 be . this be a huge step up over the original mass effect performance so if you have play the whole series on console you can still look back and laugh at how bad it use to be . end good but do not explain the aftermath good enough . but free dlc that further explain the situation for the galaxy have be announce so there be not much to complain about there .
