The zombie game mode was introduced in Call of Duty: World at War, which was released for the PlayStation 3, Xbox 360, and PC. If you're looking for zombie game modes on the PS2, you may want to explore other titles in the survival horror genre.

Call of Duty: World at War from Activision for the Sony PlayStation 3 completely changes the rules of engagement by redefining World War II gameplay.

To win a round of Minesweeper, you must click on the board every square that doesn't have a mine under it. Once you've done so, the game will be over. If you accidentally click a square that has a mine beneath it, the game will be over. You'll have the option of starting a new game or redoing the one you just played.

Whenever you see a 1 next to a 2 against a wall, you know that the space opposite the 2 is a mine. This is because there can only be one mine in the two spaces adjacent to the 1, which means the second mine must be adjacent to the 2 in the final space.
