The single player campaign followed eight agents working for the counter-terrorist organization SION. SION stands for Special Intelligence Operations Network. The game allowed the ability to play as one of eight SION agents each with varied strengths and weaknesses. The abilities were based on speed, stealth, armor, assassin, sniper, demolitions, etc.
Unrelated to a 1996 game Vigilance On Talos V.
