Hellsound Dreams is a horror themed mod based on Nightmare House 2 mod source code.
Well this is an odd mod, its just a collection of maps trying to be spooky, with some technical elements of the NH2 mod.
Then i think what defines this mod precisely is the word "confussion", as it offers no challenges of combat or anything like that then this mods centers in stupid "go find the key" puzzles, that's probbably the most plain and lame feature of this mod: go find the key, stupid zombies, some guys with pistols and smg's and that's all.
Overal this is a very low release and i wouldn't try it again if the authors make some more silly and dull maps as this ones i waste.
As for the good points, i guess the only cool feature in this work is the new tarantula-big black spider replacement for headcrabs.....
Well designed yet sparse on information regarding navigation and problem solving, many of the puzzles had to be traversed via noclip.
Simply put, there was far too much puzzle solving in this mod and it really broke the flow of the gameplay. Even though I did figure things out on my own near the end, I still felt like I was backtracking far too much.
Overall, it's not terrible as the modder has a keen eye and definitely a talent for modding, it's just that Hellsound missed the mark gameplay wise.
