“💣🔫⚠️ Bonus Missions, Not My Favorite Condition Zero – Deleted Scenes adds extra single-player missions, but I didn’t really enjoy them 🔄💀. Some missions feel repetitive, and the campaign style wasn’t my thing. However,…”

— a player, Steam review · 16 hrs played“The single player campaign is very fun to play. If you want Half Life 1 style of single player experience in the form of Counter Strike where all of campaigns are based on real life operations. I do recommend this game.”
