As it has been said before, the two real problems with this game are the considerable lag (probably from a single server handling the strain of a game played in more than 7 time zones scattered throughout the world), and lack of accountability of players who leave during some of the higher risk games (i.e. Nightmare Mode). Granted it is difficult to enforce (as some people quite due to server failing to respond), if these problems were accounted for the game would be perfect. There are a wide variety of weapons and skill/augmentations available to essentially customize a character to a unique level. The maps are well made with only one or two glitches that are noticeable (In the mission Blackout, the loader mech noise sometimes continues into other battles or until you refresh the browser).
