Condition Zero is an underappreciated gem that unfortunately got overshadowed by its bigger brother, CSS.

People often dunk on Condition Zero for being just a reskin of CS 1.6. They may be right at one point, but CZ brought things that may not look like much, but people either praise 1.6 for CZ's features or they never really even played CZ to experience it.

For example, maps and models in CZ have so much better visual clarity. I mean, sure, some maps look completely different, straying from the original, but they do help you differentiate between CT and T quite well. 1.6 and CSS had tons of dark and damp maps where not even night vision did the work for you most of the time. CZ solves all that.

CZ brought other things to the table, though, like bot support. We all know bots, right? People often mistake 1.6 for having bot support, but not really, they came with CZ.
Later they got backported to 1.6 in cough pirated versions cough.

Also, general stability, ping, it all feels much smoother. Some 1.6 veterans may see it as a minus, but CZ does feel friendlier when it comes to actually hitting your targets. (ghost hits) I think that's a plus for a wider variety of players.

essentially CS:CZ is kind of like cs 1.7, it expanded on old with new, really harming anything from the prior

also yeah theres the entire PVE matches stuff and even whole campaign packed into it, people who never even touched cz tend to dunk on that also, maybe give it a try, it serves as bonus content, if you hate it then dont play it, but dont set the entire game on fire for it.
