I waited until more maps were reworked to play this. And with the Italy chapter completed now I decided to play through it.
Where do I begin? I guess I'll start with what I didn't like. The main one is framerate, but thats not your fault, and it felt smoother than I remember those levels being, not sure if it's your doing. And thats about it; there's a couple of spots where you can go out of bounds but I didn't care. Also Exitus Acta Probat took me to the menu rather than to Gates of Heck.
Now, this has some of the tightest combat encounters I've seen in modern Sam. The difficulty was just right, the enemy placement was great, the enemy choice was good, the progression felt great, and it felt like all fights had a lot of thought put into them. The pacing I think is too fast for someone who hasn't played SS4 before, but as a replay it's excellent.
I loved the machete, very good against zealots and it felt great to get a bunch of enemies lined up. I loved even more that you lose all your gadgets at the end of each level, which made me use them a lot more. I liked the enemies patrolling, the floating weapons made them stand out more, and the new music of Gates of Heck slaps. I'm sure I'm missing more stuff. The highlight for me was that Khnum arena at the end of Exitus, beautiful stuff
