Most of the songs for the Summer Sideshow event are pretty rad.The Main Theme of the Summer Sideshow the aptly titled 'Step Right Up' is pretty rad.Oddly enough, it didn't appear in the official soundtrack. 'This I Know', while being an epic track in itself, it has an unintentional Title Drop which makes it the de facto Title Theme Tune.The rest of the soundtrack can be like this too, especially if you like metal (specifically bands like Demon Hunter and zYnthetic, as they take up a good portion of the soundtrack). 'Collapsing', while not made specifically for the game, is an epic piece to rock out to while massacring the army of Zeds 'collapsing' on you.'Die Volter', Hans Volter's boss battle theme, is an intense piece that'll get you pumped as you take him on.If you don't use said trick though, he will offer more of a challenge. Due to this, the battle with him can be over in a minute or less. The Patriarch is considered to be one by veteran players for one reason: It is very easy to bodyblock him with a Berserker and prevent him from escaping to heal up, while the rest of the squad mows him down.He has a laser attack which deals a lot of damage, but this can be avoided simply by ducking. This makes fighting him amount to kiting around the map and parrying his attacks to de-rage him. Though this sounds scary, since the Fleshpound is probably one of your most formidable foes, King FP fights you alone with only the occasional quarter pound showing up. King Fleshpound is basically a souped-up version of a normal fleshpound.A few other maps and modes have other characters taking on the role of the TRADER Pod, but while most are appreciated ( Gary Busey as 'Badass Santa' in Santa's Workshop and the Patriarch constantly belittling you in most maps on Endless mode), Airship brings back Ringmaster Lockheart, who is often muted solely for the fact that he talks like a Borderlands character, in that everything he says is done with too many words and a lot of forced quirkiness.The TRADER Pod will remind the player to buy ammo or armor if you're low whenever you bring up the menu, and especially in solo play she'll also remind you to heal yourself at the end of a wave.

It is a real gun, although obviously it hasn't seen widespread use. Aluminum Christmas Trees: The AF2011 was thought to be a fictional gun due to its weird design, a conjoined Colt 1911 lookalike.
