Cyber Troopers Virtual-On Oratorio Tangram
Plot. The game starts 20 years after the events of Operation Moongate. After the defeat of Z-Gradt, the mightiest VR and the final boss of the first game, humans continued to battle in their VR's, searching for supremacy. However an unknown AI known as Tangram has awakened and became self-conscious. With the directive to destroy humanity, Tangram infected Earth's mother computer with a virus called "Tangram Virus" and hacked into all VR systems, except for the player's VR. It plans to use the infected VRs to destroy the last  human colonies that survived the previous war. The player begins the mission to defeat all VRs and destroy Tangram to stop its evil ambitions once and for all. After defeating all VRs, the player is teleported to the Earth's mother computer system to fight Tangram. Depending on the final battle outcome, there are two endings available. Good Ending: Tangram is erased from the computer and the player's VR is teleported back to Earth's stratosphere, where its armour is critically damaged during the fall but is saved by VRs that came on the Floating Carrier. Fei-Yen is  saved by Angelan or the opposite and the others (Temjin, Raiden, Dodray, Bal-Bados, Specineff, Cypher, and Apharmd) are saved by the same model VRs. Bad Ending: If the player's time counter reaches 0, Tangram hacks into the player's VR system and shuts it down, resulting in a Game Over screen. Reception. The Dreamcast version received favorable reviews, while "Ver.5.66" received "average" reviews, according to the review aggregation websites GameRankings and Metacritic. Stephen Frost of "NextGen" called the Japanese import of the former console version "an impressive game, and practically a perfect conversion, marred by difficult controls and  a lack of 'compatibility' with the standard Dreamcast controller. However, if you're willing to invest the necessary time, you'll eventually discover that the game provides one of the most addictive and deep gaming experiences currently available on Dreamcast." In Japan, "Famitsu" gave the same Dreamcast version a score of two tens, one nine, and one ten for a total of 39 out of 40. "Game Machine" listed the arcade version on their May 15, 1998 issue as being the second most-successful dedicated arcade game of the month. "GameSpot" gave the same arcade version seven out of ten  and said, "Provided you can get the twin sticks, "Virtual On: Oratorio Tangram" is a must-buy. Without the controller, or an edit-controller function, it's a must-avoid."
