Space Invaders DX/Versus Mode

As mentioned on the Walkthrough page, if you select this mode, you and the other player shall have ten seconds to choose one of three difficulty levels (EASY, NORMAL, and HARD), by pushing the joystick left and right, then pressing the Firing Button to confirm your choice; once you have done this, a formation of twenty invaders (five large, ten medium and five small), along with one shield, will appear on both players' sides of the screen. Some of the invaders may be coloured yellow, red, blue, green and pink - and killing them will cause the following effects (to the other player, in case of a blue one): If either player gets hit by a bullet and "killed", everything on their side of the screen will turn red for a few seconds (until they get resurrected); once one player has killed all of their invaders (or the other player's invaders have reached the bottom of their screen), they shall receive a silver (for Player 1), or gold (for Player 2) coin (but, if both players' invaders reach the bottom of their screens at the same time, the text "DRAW" will appear). Once one player has received between three and five coins, they will have won the game - and the sun will rise over the winning player's city, as the text "WIN" appears, while the losing player's city will explode and leave a crater behind as the text "LOSE" appears. The text "GAME OVER" will now appear on the screen.
