Borderlands2 is a cartoon looking RPG that continues the story line from the first game. It has thousands of guns, 4 none DLC playable character types, and a free-roaming campaign.
World changes as you advance in the campaign,
Loads of guns, grenade mods, NPCS, and unlock-ables,
2 Player campaign, online and split-screen, although split-screen isn't that good.
Split-screen is hard to use,
Controls are hard to get used to,
Not as many gun cases as the first one,
There are not vary many mini-games/other things to do besides quests,
Snipers aren't as good as the were in the first one.
Borderlands 2 is not just a sequel but a huge new story that you can pump a few hundred hours into. It's one of the best co-op games on the market, and the new character classes give you a ridiculous amount of replay. Borderlands 2 is my favorite game of the year so far.
There are few games that cause my work and social life to decline that they absorb so much of my time. B2 is one of them, and it's addicting looting, leveling up, and side quest hunting still have me thinking Pandora 24/7.
The 5 character classes are all amazing, and the 3 skill trees within each class give you totally unique gameplay experiences. It's crazy deep, with a level 50 cap. And then there is the treasure/loot collecting and a gazillion guns to try out.
The Commando class unleashes a nasty turret as the ability. Sirens have cool biotic like powers. The gunzerker midget guy is super fun and can go crazy with 2 guns at a time. The Assassin class is a freaking ninja master- my personal favorite, slashing up dudes with my hatori hanzo sword. The DLC Mechromancer class can summon a deathtrap robot to help fight, which is awesome.
B2 in all its glory still has issues too. Why doens't Gearbox create co-op play like Dead Island where you can play with any level friends, so that enemies are at your current level regardless of your allies. It makes it way too hard to play with people that aren't at the exact same level and point in the game. It's also next to impossible to get rare orange loot, and I've pumped over 100 hours in so far with 4 classes and I've only found a few pieces---even the last guy in the game doesn't drop that good of loot half the time.
There's a few other hiccups but I'd rather praise Gearbox Software's masterpiece. What it comes down to is that B2 is simply a ton of fun, extremely addicting, and gets better with the more friends you have. Not a lot of games nail on all those elements. A MUST BUY!!
