Dennou Senki Virtual-On: Force (電脳戦機バーチャロン フォース) is an arcade game developed by Hitmaker for the Sega Hikaru arcade platform in 2001. Despite its potentially misleading name, Force is a sequel to Cyber Troopers Virtual-On: Oratorio Tangram, standing as the third "generation" in the series. It has thus far never seen a release outside of Japan (however, it is region free).
Several minor variants of Virtual-On: Force exist; 7.5, 7.6 and 7.7. Unlike the revisions of Oratorio Tangram the updates exist only to balance characters and address bugs.
The primary new feature of Virtual-On: Force, alluded to in the game's name, is the ability for four players to compete simultaneously, replacing the one-on-one battles seen in prior games.
Virtuaroids
Cyber Troopers Virtual-On: Oratorio Tangram introduced the concept of a Virtuaroid "series", in which multiple variants of a Virtuaroid are playable (in that game this applies to the APHARMD B and APHARMD S, differing only by the components that are equipped). In Virtual-On: Force, this is applicable to all Virtuaroids, significantly boosting the character roster.
On top of this, each of the main Virtuaroids have ten different selectable palettes (as opposed to the two seen in previous games).
Unlike its predecessors, Virtual-On: Force was not released for home platforms of the day, but was eventually brought to the Japanese Xbox 360 in 2010. Instead home console owners would receive Cyber Troopers Virtual-On: Marz in 2003, a game derived from Force but with numerous additions for the home market.
Initially the Xbox 360 version also came in a "Memorial Box" to celebrate fifteen years of Virtual-On. It was distributed with Dennou Senki Virtual-On Official Sound Data 4x6 and a code which, when redeemed, allows players to chose extra "bust" sizes for the "female" Virtuaroid characters.
