So finally got some time to play the Mass Effect 3 multiplayer last night, still very active and had no problems getting into matches. Really enjoying it and overall very pleasantly surprised at how well done it is, with the various objectives to mix things up and stay fresh each round. I also like the fact that there's different characters with their own powers like the Vorcha etc. Saw some player running about as a Collector and it looked like a ton of fun to play as. I can definitely see me getting some playtime out of this as long as the community remains. I'm honestly surprised it's still going after 4 years but I guess there's nothing else like it in the Mass Effect series and it is the only game with multi so keeps everyone in one place. Plus no splitting of the community due to all the DLC being free.
I put way too many hours into the multiplayer, and one of the reason was because of the amount of characters and different playstyles that were possible.
Using Infiltrators as an example, the Geth was more of a cloak and snipe powerhouse. On the other hand the N7 Shadow was a more up close, CQC character. Or you could play a ranged N7 Shadow.
The game made soloing interesting, fun and possible. I solo'd platinum with majority of the characters, using multiple builds so the amount of freedom it gave you to effectively play each class added to replayablilty. Then there were characters that shined in a team environment. Setting up tech/fire/biotic explosions working in tandem with another player to just clean up wave after wave in seconds..
Mass Effect 3 is simultaneously my favorite game of all time and also my most hated. MP was fantastic and I could still play it today if I wanted but the single player was so bad I almost didn't even play the MP. I think what made me give it a chance was seeing my brother play it when the first DLC dropped
and like Bisnic said, it's crazy because when they announced MP almost everyone hated the idea.
