The one major addition to the game's multiplayer suite that really takes things to the next level is Specialists, class types which can be selected prior to battle, each gifting the player with a set of weapons and abilities to give them the leg-up in battle. Some of the more memorable weapons include Gravity Spikes and the explosive bow-and-arrow known as the Sparrow, while ability-wise, Glitch allows you to teleport to another position on the map, and the controversial Rejack will bring you back to life after being killed (unless killed by a Specialist weapon, in the interest of balance). There's enough variety here that you'll take a little while to figure out which of the Specialists works best for you, but they're all terrific additions to the combat and add yet another layer to the ridiculous array of customisation the game's online offering affords you.
