Your name: Jones. David Jones. Your mission: to save the world from Russian terrorists and other shadowy figures by taking them out before they know what hit them. Trigger-happy gamers may be disappointed by IGI-2: Covert Strike's emphasis on stealth over slaughter. Still, the game's tension-packed atmosphere and large levels -- though lacking the similar ''Splinter Cell'''s pizzazz -- make it an FPS standout. Sure, we've seen it all before, but Mr. Jones' latest mission is a clandestine success.
