Starstorm is a DLC done right, it includes a lot of content for a cheap price. You gain access to 5 new nauts, Ted McPain, Penny Fox, Sentry X58, Skree and Nibbs who all standout on their own and are a lot of fun to play as! You also gain access to their themes and killing spree themes when you play as them! Additionally you gain some new songs to listen to, replays so you can show your friends your matches, custom game settings and more! One thing that is bashed about the DLC though is that it's Pay2Win, it isn't, it's just that 4 of the 5 characters are more offensive and focus more on killing rather then anything else, plus they are dead easy to counter, so it's pretty much your fault if you die from them. Overall if you see this on sale, grab it, Starstorm is one of the best DLCs ever made.
