Syphon Filter 2

Syphon Filter 2 (PS1, 2000) is a tense stealth-action sequel that sharpens the original’s formula with dual-character missions (switch between Gabe and Lian on the fly), expanded stealth kills, and a globe-trotting conspiracy. While its tank controls and clunky aiming show their age, the gritty tone, iconic taser-frying enemies, and split-screen multiplayer (RIP servers) make it a PS1-era gem.
