I have the 2.2 version of this mod and I don't know if it's the same version as this one (2010), that's why i am rating this 9 instead of 8, because it looks like it has better graphics and sound and more stuff than my version has.
So this is surely the best gameplay overhaul mod for STALKER. If you think that the highest difficulty isn't enough for you at all, then you should surely go for this mod. It makes it a way more challenging survival and also more horrorish game. It adds some monsters and features that were removed by the GSC (for an unknown reason, perhaps not enough time) and those are really great. For example a zombie that have no weapons, he only follows you, but he is quite tough. It's really awesome when they spawn in a horde with a controller and trying to fight them off, for ex. at army warehouses, freedom base
It also adds some cool new weapons, I really love the M9 Beretta, the best pistol for me. Lurk mod doesn't have M9. And I think that the Lurk mod could be compared to this, but it seems to me like it's removing all the stalkerishness from the game as it adds M4, M16s, AUG or FAMAS with red dot sight and ACOGs, that's just too... arcade :D
I didn't give it 10/10 because some things I don't like on it, for example a controller spawning in the middle of a Bar instead of making the mutants at the outskirts near the entrance to Scrapyard able to access the Bar, that would really be awesome. But you can fight off hordes of mutants when you are in the autopark or Cordon noob camp and many more places, when blowout occurs ;)
Do you want a better, more challenging gameplay, because you don't want to play vanilla again? Go for this mod. Are you playing STALKER for the first time or do you strictly want the old gameplay with new graphics? Go for Complete. Do you want STALKER to be easier and do you want really lotsa new weapons, even more than in OL? Go for Lurk
This game had a lot of potential but was severely lacking.
To me it seemed unfinished, with an ending that could have been drawn out a bit more.
The purose of them game was to insspect items to find your way out of the room, but there werent enough items to inspect and it was very unrewarding.
This mod isnt worth mutliple playthroughs but should be experienced at least once.
After I tested this mod for a while, I have to say that this mod is realy awesome, it adds a lot of usefull things and so.
You can try new strategies.
But why only 9/10? Because of the bugs, wehn the most are fixed it will get 10/10 from me.
Superb mapping/lighting and pacing.
Only caught me out one time through the entire thing where I thought I was supposed to kill the gunship (with one rocket) for finding the stash.
Some nice little scripted environmental hazards and all in all a well polished piece of work!.
The only letdown was the very simple story but it's still more than worth playing for the 2-3 hours fun it will give :D.
Oh and Rocket chair for the WIN!!
