Taito Legends 2: Day Eight.

The year 1990 saw the release of the game Super Space Invaders '91. This update to the original Space Invaders adds a bunch of new things to the classic formula. Your ship still moves left and right across the bottom of the screen while shooting at invaders that are eternally edging closer. The game now features colorful backgrounds with the stages taking place in various locations such as Earth and outer space. The enemies aren't limited to their original movement pattern. They can now move in various different ways ranging from Galaga like swooping attacks to Gyruss like flight patterns. The game allows for power-ups and special weapons. They've even incorporated boss battles. The game has a more whimsical nature as evidenced by the stages in which you must protect a herd of cows from the aliens out to abduct them. The colorful but decent graphics and the fun music and gameplay make this one well worth playing.

The year 1991 saw the release of Metal Black in the arcades. The game is the evolution and pseudo-sequel to Gun Frontier. This time around the game has moved from being a vertically scrolling shooter to being a horizontally scrolling shooter. The setting has moved from the bizarre future and wild west weaponry themed Mars to a future post-apocalyptic somewhere. Beyond that the game features the standards of the genre. The graphics are actually quite impressive and the boss battles tend be long and extravagant.

We move ahead to the year 1992 for the final game of this entry with Grid Seeker. The game is another vertical scrolling shooter with all the standards of power-ups and lengthy boss battles. This one is set in the as of then distant future of the year 1999 during the second Persian Gulf War. You can choose between three types of aircraft, a helicopter, a stealth fighter, and a stealth bomber. The game has an intro that gets you ready for some serious modern war action. Except it becomes obvious that their version of the future seems a tad far more advanced than how the year 1999 actually was. The vehicles employ R-Type like vehicle attachments that act as shields. You actually need to catch enemy fire with them to build up your firepower and bomb strength. The game tries really hard for epic boss encounters but they come off as more overwrought and tedious than anything. This one is more for the dedicated.
