Xevious is controlled by using the keyboard. The Z key is used to shoot and the X key drops bombs.
Xevious is a vertical shooting game that was designed by Masanobu Endou. The game was published by Namco in Japan and Atari in North America. It was released in arcades worldwide in 1982. it was ported to numerous home systems such as the ZX Spectrum, Atari 7800, and NES throughout the 1980s.
Xevious used the same hardware as the earlier Namco arcade game, Galaga. Like Galaga, Xevious was one of the first vertical shooters and innovated the genre. It was one of the first video games to feature hidden bonus items and one of the first shooting games to feature the use of a primary weapon and secondary bombs. The scrolling background is another innovation featured in Xevious that made its appearance in numerous other vertical shooters including Raiden, Aleste, and Strikers 1945. Xevious did not see ground-breaking success in the United States (although it was one of my favorite games), it did establish a status as a cult classic game in Japan.
This Flash version of Xevious is an emulation of the original arcade game. When you first start the game, you will be prompted to insert a coin; click your mouse to simulate the insertion of a coin and once again to "press start". The graphics and sound effects remain the same between this Flash game and the arcade game that it emulates, but the gameplay is sped up tremendously, making it much more challenging. There is also an issue with rapid-fire; you can press and hold the fire button to shoot at an extremely-rapid rate (far beyond that of the original game) as long as your ship is standing still.
This Flash port of Xevious is not perfect, but if you need a shooting game fix, then it is much quicker to load it up than it would be to download an emulator and ROM. If you are a fan of vertical shooting games, then check out the arcade game that added innovations to the genre, Xevious!
