Let me start off by saying the multiplayer is very fun, but there are some problems.
For starters, the sniper is much easier to use than even in Reach. It is game-breaking to have the stay-scoped-in-while-shot-at feature. I get so many kills so easily with it. I have sniped more people out of vehicles that I did in Reach. My first game I used it I got an untouchable. I am almost maxed out on its commendation.
The biggest flaw with multiplayer though is keeping active camo an AA. It is so broken it’s not even funny. My personal opinion would be to remove it along with every other AA, but that is just me…
