The main character of this game, Claude, does not say a single word throughout the entire game, though you can hear him grunting when he falls after jumping and groaning if he ends up drowning in the river.

The main character's name is later established as Claude. You can find this out after completing the storyline of Grand Theft Auto: San Andreas (2004). It is assumed that Claude is Claude Speed, the main character from Grand Theft Auto 2 (1999).
