Microsoft announced this morning that two more games would be making their ways to the Xbox Live Arcade on the Xbox 360. Both games will be made available for download on Wednesday, April 18 at 2 a.m. Pacific Time.

Fans of classic-shooting action should be pleased to hear that Konami is bringing its coin-op tube-shooter Gyruss to XBLA. In Gyruss, gamers are charged with flying a space cruiser from Neptune to Earth, all while battling enemy ships, satellites, laser-beam generators, and asteroids. The game has been enhanced for XBLA with the inclusion of voice support, new 3D graphics, digitally enhanced sound, and leaderboards. The original arcade version of the game is also included. Players tired of lonely nights spent hunched over their console by themselves will be able to take advantage of the game's multiplayer split-screen cooperative and versus modes. Gyruss will provide players the opportunity to earn up to 12 Achievements for a total of 200 Gamerscore points. Gyruss will be available worldwide for 400 Microsoft Points.

Those of you out there who like your XBLA games original can rest easy this week. Not only will Microsoft be bringing the classic arcade-stylings of Gyruss to XBLA, but the company will also release the Sierra Online-developed 3D Ultra MiniGolf Adventures. 3D Ultra MiniGolf Adventures includes 36 challenging holes, over-the-top power-ups, and three major theme courses: Classic Carnival, Old West, and Outer Space. The game will allow for up to four players to compete over Xbox Live, and will offer 12 Achievements for 200 Gamerscore points. 3D Ultra MiniGolf Adventures will run you 800 Microsoft Points.
