Acquire Games

Acquire's 1998 PS1 stealth-action game and the originator of the PlayStation stealth genre — Tenchu: Stealth Assassins places players as feudal Japan ninja Rikimaru or Ayame completing assassination missions through populated environments using shadow movement, tool usage, and the grappling hook, establishing the stealth assassination mechanic that Metal Gear Solid's success that same year confirmed was a genre with mass appeal.
