This is me (AznKei) playing Left 4 Dead 2 in single player with the K-ON! characters starring Yui Hirasawa, Ritsu Tainaka, Mio Akiyama, Tsumugi Kotobuki and Azusa Nakano, replacing the original survivors Nick, Ellis, Rochelle, Coach and Zoey.
The game is about 4 survivors immune to The Green Flu, which turns most humans into zombie-like creatures, who must escape the apocalyptic pandemic by defending themselves. Hard Rain is the fifth campaign of the game where the survivors has been given a mission by Virgil to find and bring back diesel fuel for his boat by dropping them off to the Sugar Mill factory while a hurricane heads up to the area at the same time.
This game is made by Valve and the K-ON! survivors mod is made by Wheezle. The modded sound effects were made by Kim-Kim.
