I'd love to be in the run for the skins.
I've only reached rank 22 so far (I think the highest is 40).
The multiplayer is ok.
A quote from my favorite Muppet critics sums it up well, "Hey this isn't half bad" "Yea but it's not half good either"
My first issue with the multiplayer is that the maps are entirely taken from the first game, they literally copy and pasted sections.
The second problem is weapon imbalances. Pretty much everyone picks up the grenade launcher when it available and thus the spam fest begins. And it is available pretty early on. You'd think that maybe the weapons later on would probably be stronger, but they are terrible. The nail gun is pretty much the machine gun with a charge up time. The elephant gun is a double barrel shotgun. And the crossbow is a pistol with a single shot and a long reload.
The starting plasmids are also overly strong compared to the laughably weak plasmids you unlock later.You start with ice, fire, and lightning. You later unlock telekinesis, areo dash, Houdini, and bees.
Areo dash has a terribly weak hit detection especially since there is a lot of lag with player hosts. The basic idea is you dash towards an enemy, hit them and stun them, the problem with this is that most people will throw a plasmid in your face as you dash towards them or just instant kill shotgun you as you get close.
Telekinesis you grab random rubble and chuck it at enemies, but odds are you grab something incredibly tiny and even then it doesn't do a ton of damage. You might think hey I can grab one of those lovely exploding barrels and chuck it at some one. This are incredibly devastating, but obscenely rare, and even then finding one and carrying to to an enemy to throw at is a hassle because you're EVE levels drop rapidly the longer you hold an item. Houdini is basic invisibility but once again its another poorly conceived plasmid you go invisible but it only last a few seconds, and you leave a huge puff of red mist entering and leaving it. And since most people have the grenade launcher most people will shoot in the general direction of the mist and nail you.
Bees is pretty much just an attack that is meant to bother the enemy, it does very little damage but obscures the enemy. Pretty much anyone who has this on them will just spray gunfire and plasmids in your general direction.
The level of customization is really shallow, it was advertised as having trials like MW2, so I figured hey I use X gun a lot so I'll get attachments and whatnot, the same with plasmids. Unfortunately this is not the case, the guns get attachments based on what level you are and not based on whether or not you complete the trials. The plasmids never get any stronger.
Overall it isn't bad but I really wish they did more, it seems that it was quickly slapped together, especially since they didn't really have to create unique maps.
The one really nice thing is that people who really are rabid about the story, you unlock extra audio diaries to listen to as you rank up. And it gives some backstory as to what happened right after the New Year's Eve party.
