Caved and used my last (for now) key at Level 24 and got two pretty good pistols. Best of which is a 730 Jakobs pistol with great fire rate. The other was a 460x2 which uses double ammo but has much slower fire rate, so I'll probably just sell that one
Anyone else do the mission for the Slab King where you have to defend the Hyperion Supply Crate? Is the crate supposed to open afterwards or what? I got the XP and a bit of money, but was hoping it'd open and have a weapons chest in it or something.
Also did the mission in the Holy Spirits bar where you have to follow the leprechaun to the money stash. Really funny stuff. Spoiler: "Oh, I can't wait until I get to the stash and nobody ambushes me and kills me. That's my favourite part!"
