makes the entire rest of the game pointless. That AOE ground slam is ridiculous. After hundreds of hours, I have only beat that first boss a handful of times. Totally killed the game for me.

Title says it all. Any way to get the last 2 guns? Razorgun and Tesla?

Using melee doesn't make your character turn to face, just like any other weapon. It should have the same mechanics. That's why melee seems messed up. you can't ever face them because the dev forgot to link that function to it. And the other, I think, I was thinking of the reloads for the M60. You wouldn't empty the magazine to then just refill it, you would fill it with what was missing. That's one reason that weapon seems messed up....

when will items return to market, or will they?

just started this week.
