I've tried this mod, and wanted to get back here to leave a feedback about it.
First of all, I feel really sorry for all the poor guys for whom the mod doesn't work right. I followed every single step in the readme file and mine got installed well. So I feel sorry for these guys because this mod is probably the best I've ever played !
The first thought that came to my mind while playing this mod was : "Damn, the author must be proud of himself, there's not even a shred of a bug". Reading the error logs, I was affraid the mod would have crashed, and yet I easily finished every level in a row with no bug or crash.
Another point that left me voiceless was how the different weapon customizations really brought, each of them, a new interest in the gameplay. The different smoke grenades give a real tactical opportunites (even though I noticed that sometines AI could actually see you through the smoke, but that doesn't matter), the different ammo types for the SOCOM make it useful (at last !), sniping with the bullet drop and tracer ammos is just as joyful as wiping your ass with silk. Every single detail in this mod is just amazing.
I even found an easter egg left by the author. Of course, in order not to spoil anything, I won't say in which level I found it, and I won't even say what the easter egg is, the author knows what I'm talking about
So, it took me only 4 hours to finish the game with this mod because of how addictive it was, and I didn't even find all of the attachments (didn't find the TAC grenades for the grenade launcher), making this mod by far the best I've ever played.
If I could suggest one thing to the author, probably the only thing left aside and that could be a great idea, it would be to add more scopes. I'm suggesting that because I did it myself once, I had downloaded the CustomAttachmentByVertX and thought they were awesome, but I was also loving the original ACOG look-a-like assault scope, so I decided to integrate VertX's attachments as new attachments, with different properties, and could easily change between an ACOG scope and VertX's Aimpoint sight while on the battlefield.
Also, as the author seems to really know what he is talking about when it comes to military stuff, I'd suggest to rename the Reflex Sight and the Assault Scope into EOTech Sight and ACOG 4X32 scope, since these sights obviously look like an EOTech and an ACOG.
I already applied these two suggestions for my own use on my computer, but I'm suggesting that so other people downloading your wonderful mod could enjoy these names and new scopes on their computers.
Anyway, even without this, this mod is just perfect !
