It is also not uncommon for visual novels to have multiple protagonists giving different perspectives on the story. C's Ware's "EVE Burst Error" (1995) introduced a unique twist to the system by allowing the player to switch between both protagonists at any time during the game, instead of finishing one protagonist's scenario before playing the other. "EVE Burst Error" often requires the player to have both protagonists co-operate with each other at various points during the game, with choices in one scenario affecting the other. "Fate/stay night" is another example that features multiple perspectives. Chunsoft sound novels such as "Machi" (1998) and "" (2008) develop this concept further, by allowing the player to alternate between the perspectives of several or more different characters, making choices with one character that have consequences for other characters. "428" in particular features up to 85 different possible endings.
