As an Expanded Game released in 2002, this title revises the core tactical espionage shooter where you infiltrate locations to stop terrorists from using stolen technology. Beyond the main story, this version offers significant replayability through over 200 VR Missions focusing on specific skill challenges, alongside Alternative Missions involving tasks like photography or bomb disposal, providing varied gameplay perspectives.
As an Expanded Game, this release takes the complete, original cinematic espionage shooter experience and significantly augments it with substantial bonus content.

This specific release is classified as a remaster/revision of the parent game. It does not feature any separate downloadable content (DLC) or subsequent expansions released after its initial launch. It stands as a complete package containing the original adventure alongside its integrated bonus content.
The gameplay blends elements from several genres. While fundamentally a Tactical adventure focused on stealth, evasion, and non-lethal approaches, it also incorporates mechanics from the Shooter genre when combat becomes unavoidable.
