The major issue with the Hammon fight is this: I am assuming the meteors are supposed to do splash damage based on where the red target reticle is? Similar to TNT, yes? Instead they only do damage where they pass through the screen on their way to the reticle. I have stood on the red targets repeatedly and have taken zero damage from the impact, but I have been killed 40+ times (seriously, I kept a tally

) by the meteors striking me on the way to their target. I have been killed 10+ times before the fight even starts during Hammon's speech because of this. There is nothing more frustrating than blowing off 3 of Hammon's legs and then die because a meteor that you cannot see comes from offscreen and kills you. Especially when you are also juggling Hammon and the 4+ bandits he will spawn.
A secondary issue is TNT. The lack of TNT available drags the fight on to the point where it goes from being challenging to being tedious. Having a respawning stash of 5 sticks or so nearby (a gift from the shopkeep?) that you could pick up prior to the fight would alleviate this. The meteors could also spawn them. It gets very very grindy to have to build up a TNT stockpile by just killing bandits. Not so much in the later half of the fight when Hammon starts spawning 4, but prior to that the fight just drags on. Plus it gets very frustrating to watch your TNT stash deplete because the ham hock bounced out of the way at the last second. Alternatively being able to have a save file that you could load instead of the one auto-save would help with this or being able to respawn with the items that you had prior to the fight would also drop the frustration level a good deal so you don't have to backtrack constantly to get supplies for this fight.
Lastly, the legendary rifle. I read that you could one shot Hammon with it but whenever I use it he does this Psycho Crusher spin thing and knocks it out of my hands. I assume this is intentional and you need to blow off his legs first. Sometimes when I have used it, however, Hammon will get locked into his Psycho Crusher animation and won't come out of it. He will stay there forever and the only thing to do is to save and quit.
Anyway, sorry to dump all that negativity. It really is a fantastic game, but this is the one part where the game feels really imbalanced.
