OK, just finished my first game and got a few questions...
What's the benefit of selecting that Second runthrough? I've just completed the main game once, why run it again?
On my first runthrough character I'm playing whichever dlc it is that centers on T-Bone Junction. Why is it that every time I end my current game I end up back in T-Bone Junction? I left off in the prison, but when I loaded my game again I'm suddenly back in T-Bone.
And I thought all the first runthrough claptrap rescues gave you backpack slots as a reward? The prison one gave me a grenade mod, and I ended up switching off the game before it saved. Is that not a slot upgrade reward for that mission??
And I'm currently at level 40. When does the decent gear start dropping? I'm using a level 18-20ish SMG and rifle because nothing at all has dropped with better stats in 20 levels. These two are worth about 10k each, with 100k gear dropping that's complete crap compared to these two items.
Second playthrough will have tougher enemies and higher level loot.
That's the way all of the expansions work, you end up at the initial teleport location every time you exit the game and come back. It is a bit annoying.
I don't believe you get extra slots from the DLC claptraps. I think the maximum is somewhere around 40, maybe 42?
I'd say your best bet for better gear will be when you get to Crawmerax in the T-Bone Junction DLC. You can post up on the left crack where he can't get to you (check youtube so you know what I'm talking about) and you can just create a new character and play split screen and use the extra character to coax him into turning around so you can shoot his back until you get an Orion (sniper rifle that ricochets, once you have it you can ricochet the shots onto his back by shooting a pillar beside/behind him).
If you can't beat him, then your next best bet would be New Haven chest farming on your second playthrough. There are tons of videos out there explaining what to do, so just check youtube.
