Also - and I don't mean to double post by the way, but thought people would want to see this - I went to PAX East today and went to the Borderlands booth and learned a lot more about the game:
I waited about an hour and a half to play the game, but Gearbox totally trolled us and had us just watch someone else play the game ): Either way, the game actually plays really well! They played as Athena and my god, she's essentially Captain America. Her "skill" is that she uses a shield to absorb bullets and then after time throw her shield at her enemy (kindove like how in Titanfall you can absorb bullets and then throw it back at them). They actually showed that you can have teammates fire at your shield when activated and essentially you can do that to power it up and throw it at them. Furthermore, when you have the shield activated, you can shoot bullets with a gun in the other hand, so it basically makes you invincible for a short period of time. When you max out her skill tree, you get the ability to throw her shield at multiple enemies; it will chain combo and travel to up to 4 enemies I believe, practically instant killing them.
They didn't really touch on the gunslinger, but they told us about how Wilhelm works a little bit. Supposedly, as you level up his character, his body changes as well, as he'll become more robotic with weapon attachments (almost like he's transforming into the Wilhelm we know from Borderlands 2). Claptrap - like I guessed earlier - actually does wear hats as his customization xD He's actually a lot shorter than the other characters, so it would be interesting to see if his line of sight is closer to the ground than the other characters. They didn't show him jumping, so I don't exactly know if he has that ability or not, but they did say that this is the same Claptrap that finds you at the beginning of Borderlands 2, not a random one like the ones in the first Borderlands.
With the actual gameplay, they introduced a few new type of weapons. One of them is an "ice beam", which essentially freezes your opponents and you can use the slam attack that they talked about while double jumping to shatter them into millions of pieces. Another kind of gun is a "lazer gun," which comes in 2 different variants; one that will shoot out into bursts (like how you'd see in a Star Wars movie) and one that is a constant stream (like how you'd see in Ghostbusters). The addition of an oxygen supply also isn't a deterrent I realized. The oxygen bar goes down pretty slowly, and the game has many, many oxygen pockets on the moon so it's not like one of those horror games where you have to constantly monitor your oxygen tank. Although it's still quite useful, as when you double jump it releases oxygen as well as I think they said that if you use guns that use fire element or electricity that it will reduce your oxygen supply as well. However, there are items you can use that will create "mini zones" of oxygen so you can use them in the midst of battle and not have to worry about losing any oxygen.
There was only one minor thing that really bugged me. If you didn't know, the game was made by 2K Australia (the same company who worked on the Bioshock series mind you), and a lot of the voice acting in the game clearly has a pretty thick authentic Australian accent. I don't know if they'll change that for later on, but it was a peculiar thing that I picked up on while watching the game.
That's all I can remember at this time. The graphics of it are absolutely stunning by the way, I think they actually upped it from Borderlands 2 surprisingly. Sorry again for double posting, but I felt like posting before I forgot all this knowledge that I gained today :3 If I remember anything else I'll either edit this post or post later about it.
