Warp & Warp

Warp & Warp (ワープ&ワープ) is a multi-directional shooter arcade game that was released by Namco in 1981. The game was later ported to the MSX, and a sequel titled Warpman (ワープマン) was released for the Famicom in 1985 with added features and improved graphics. The game was released in the United States by jukebox manufacturer Rock-Ola as Warp Warp.

Gameplay
The objective of the game is to pursue the mystery aliens by warping across two different worlds: the Space World and Maze World. The player may choose when to warp to a different world, so it is possible to continue playing in the same world throughout the game. In Space World, the character uses a gun to shoot up enemy aliens, and in Maze World, aliens are killed using a time-delay bomb. The delay is controlled by the length of time the button is held down, and the player loses if the character is caught in the resulting explosion.

Power-ups may appear on some levels, and allow the player to shoot exploding bullets or attach bombs directly onto enemy aliens. However, the exploding bullets usable in Space World can only obtained in Maze World, and the power-up to attach bombs onto enemies in Maze World only appears in Space World. Players must alternate turns on the screen in the arcade version's multiplayer mode, but two players can play at the same time in the Famicom version. The player using the first controller controls a white Warpman, and the second controller controls an orange Warpman. Shooting the other Warpman during multiplayer mode causes him to become immobile for a certain period of time.

Scoring
There are 3 types of generic aliens (called Bemu (ベム) in the Japanese version), and killing 3 aliens of the same type and color causes a mystery alien to appear. There are also 4 types of mystery aliens, and 500, 1000, or 2000 points are awarded to the player, depending on the type of mystery alien that was killed. The fourth type of mystery alien leaves one letter from the word "extra" when it is killed off, and a 1up is awarded if the player obtains all 5 letters. The points awarded for killing generic aliens differ depending on the area of the screen they were killed in, and their color changes in each of the three areas. Aliens killed at the center of the screen yield the highest number of points, and those killed near the edges yield the lowest points. Killing multiple aliens with one bomb in the Maze World awards the player some bonus points. In the Famicom version, the high-score remains even if the game is reset, but disappears if the hardware is turned off.

The game's level is shown by the number of flags on the bottom of the screen, but the space fills up after the 48th level, and the same number of flags is shown on all subsequent levels. Similarly, the counter showing the number of lives left fills up after 4 lives, but the player can still gain 1ups to have more than 5 lives remaining in the game.
