This is one of the first Metal Gear Solid-inspired stealth games that crowded consoles at the tail end of the N64/PS1 generation. While its cover system was pretty impressive back in its day, I could never quite get it to work, and everything else about the game has been bettered in the years since. As such, I recommend watching the game's cutscenes for their terrible English voice acting, and then summarily forgetting about it, as everyone else has. (Besides me, apparently.)
