I already talked about the Condition Zero campaign in my Condition Zero review.
This Condition Zero Deleted Scenes only exists because the development of Condition Zero was quite troubled, so much so that the campaign scenes were left out of the "original" Condition Zero.
The atmosphere of Condition Zero Deleted Scenes manages to be much more "exciting" than the monotonous campaign of the "original" Condition Zero.
This Deleted Scenes doesn't have online play, only the campaign with scenes, so if you like campaigns with scenes, this Condition Zero Deleted Scenes is perfect for you!

So, Condition Zero in execution is: CS 1.6 "improved in aspects" with graphics, modeling, some weapon animations, some Condition Zero maps being at night (something you didn't see in CS 1.6)
The gameplay itself is the same as CS 1.6
And of course, we can't highlight the single-player campaign, those who like single-player campaigns may have a tiny chance of enjoying the Condition Zero campaign, as it's monotonous and tedious!
This Condition Zero is perfect for those who play the campaign and especially the online mode, which is what most people prefer.

In short, it's a cool CS, you can easily have fun online!
I recommend it as much as CS 1.6, although it deserved a little more attention from CS fans.

CS 1.6 is simply extremely fun, addictive, and has become one of, if not my, favorite games!
And since this is my first review, I'll be playing CS 1.6 for a long time, and then Condition Zero!
Someday I'll have new games and even gradually grow my Steam following!
Absolute CINEMA! <3
