Words cannot describe how amazing this mulitplayer is, i can see me loosing countless hours on it. The points system for assists and kills is amazing, i love how it properly rewards players for work they did helping bringing a target down, its a fair system that encourges alot of teamwork which is awesome.
One thing i dont like however is how you unlock races, getting them as a random unlock from a crate is total BS in my opinion as its quite possiabe that you may never get a certain race, for instance i really want a krogan soldier but so far i havent unlocked him, im level 14 and have brought plenty of crates of both varieties and all i have unlocked are humans. I think a system where you either unlock them as you level up the starting races of that class or a system where you can outright buy them would be a fairer system.
The maps so ( from the two on the demo) seem to have been made perfectly with a nice mix of open and closed spaces, not to mention there isnt any little b!tch spots where yiu can hide where the Atlas or Phantoms cant get you so you always have to think, not to mention the spawn points are located in great positions so it works womderfully.
All in all apart from one minor gripe the multiplayer is amazing, and this is coming from a die hard Mass Effect fan that truly loves the series. I admit i was un easy at first but i put faith in BioWare and boy oh boy did they deliver, they not only sucessed in making a good multiplayer mode, but ome that adds even more to the game instead of taking away like i had feared it would. Bloody good job chaps, give your selves a pat on the back.
