This game is simply underrated and feels like a hidden gem within the Counterstrike series. This game is not to be mistaken with the original Condition Zero. This entry was an interactive, single-player game that had a variety of missions to complete around the world, with different scenarios, environments and objectives to be met. Missions are not related to each other in any way, so there is no storyline that is carried on through missions. In my opinion, some moments genuinely felt tense and dramatic! Scripted sequences in some areas of levels definitely added to this. Level design was nice. Overall, fun and I will replay it at some point again.
