“[h1] The better forgotten CS 1.6 [/h1] It feels better, it looks better, it plays better. I would even dare to say it's like if 1.6 got a final 2.0 update. A good game that unfortunately was released way too late at a…”

“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…”
“Very slept on CS game. A hidden gem. - Has bots that are actually pretty decent for an old game. They'll move around the map, complete objectives, hold positions, flank, etc. They aren't completely braindead, although…”

“good game to play with the boys cs1.6 is better for playing online with over people but CS CZ is better for privite servers in my apinyan cos easy to add bots and so much easyer to make servers.”
“Better than 1.6 which is filled with fake playercount servers/full servers filled with sweats. The campaign is pretty meh but the community servers are fun and not sweaty. Also 200fps on community servers and 300-400 on…”

“[h1] [b] Counter-Strike's Forgotten Middle Child [/b] [/h1] [b] Counter-Strike: Condition Zero [/b] is, as the title says, a middle child between CS 1.6 and CS: Source that had a pretty damn rocky development cycle, but…”

“I played the whole campaign and it was not worth it i want to die please fix the stupid Ai and the bullet spread for every thing also Kenny is the GOAT”
“This game's okay with bots. Don't play the Deleted Scenes unless you're a purist. Valve was trying to imitate Call of Duty so very hard and it's such a slog.”

“i recommend it if you f with goldsrc games but damn, the challenges on this game are awful holy my... skill issue aside, maps bring me back to a nostalgia i didn't live at it's fullest (i was really really young when i…”
“This review is mainly about CSCZ: Deleted Scenes (the singleplayer missions) pretty fun short campaign, but WOW sometimes you do not get enough ammo and health for the amount of enemies it's crazy 7/10”
“I like this game, I really do. Noncampaign-wise, the game's fine. However, it's just such a piece of raw trash. Bots are terrible, have literal aimbot on highest difficulties and will shoot you even before you can see…”

“Condition Zero is an underappreciated gem that unfortunately got overshadowed by its bigger brother, CSS. like month or two later. People often dunk on Condition Zero for being just a reskin of CS 1.6. They may be right at one point, but people often overlook that CZ brought…”

— a player, Steam review · 8 hrs played“Pretty underrated Counter-Strike game. No one really cared about it back in the day, because both Half-Life 2 and Counter Strike: Source came out the same year. Nowadays it has a small, but dedicated community that is pretty chill, with all the sweats occupying 1.6 and CS2. And…”
