Borderlands as a game universe has now spanned multiple titles from multiple developers, including an excellent Telltale Games spinoff.
I'll populate this soon.
Borderlands 2 is here! [links are broken, I'll fix em soon.]
Four SIX new classes:
Salvador the Gunzerker -- Dual wields guns (any guns) Salvador's Skills
Maya the Siren -- Phaselock for crowd control, healing, damage Maya's Skills
Axton the Soldier Guy -- Snazzy turret Axton's Skills (Note: Do or Die is a 1 point skill, not 5.)
Zero the Loner -- Sword, sniper, sneaky Zer0's Skills
Gaige the Mechromancer -- Hulking robot summon, ponies Gaige's Skills
Krieg the Psycho -- BURNING HULKING RAGE ALL THE DAMN TIME Krieg's Skills
How about some gameplay from PAX (August 2012)?
It's Steamworks. Very nice.
The original Vault Hunters are all be in game as NPCs, including a 'live' Lilith.
There's a dashing bad guy, Handsome Jack, who has taken over the Hyperion Corporation and built himself a moon base from which he can shoot down robot reinforcements.
Gun manufacturers are way more significant in the new game. Bandit weapons have huge magazines. When you reload a Tediore weapon you chuck it like a grenade and it explodes (the rocket launchers actually shoot a rocket). Maliwan is sexy and elemental. Vladoff weapons have insane fire rates. Jakobs guns fire as fast as you can click/pull the trigger. Torgue guns? EXPLOSIONS! Etc. Non-gun loot (grenades, mods, artifacts, skins, heads, etc.) is also be randomized and way more diverse than BL1. Grenades that create a mob-sucking singularity before exploding in corrosive acid and also giving transfusion health? Yes please!
Main game bank for storing items and transferring items between characters.
New currency: eridium. Can be used to buy inventory, ammo and bank upgrades on the black market.
Lots of new bad guys - mobs and bosses - including some that will evolve Pokemon style into much more dangerous forms if you don't kill them quickly.
Character skins and heads
New element: slag! Slagged enemies are more susceptible to damage.
You can move while in Fight For Your Life mode - yay!
New end game raid boss -- Terramorphous the Invincible -- supposed to make Crawmerax look like a sea monkey.
Gearbox has committed to 4 DLC, along the lines of Knoxx in scope they say, by June of 2013. Price is $10 each (or comparable) and there is a season pass to get all 4 for $30.
And, oh yes, midgets on shields...
