A series which has sold over 60,000,000 copies worldwide since it began back in 1996, Resident Evil is perhaps one of the most beloved video game franchises on the planet. With its intricate story, convoluted mythology and devoted fanbase, the series has spanned over four generations of home consoles, producing an estimated seventy-five titles, including spin-offs, remakes and HD re-releases. Considering the sheer amount of games in the series, you can bet theres been a fair share of WTF moments scattered throughout. From Jill sandwiches to poorly executed live-action cut scenes, and from gun-toting zombies to ludicrous quick time events, Resident Evil has had an interesting life these past twenty years. The series has moved from traditional survival horror to action-adventure, from janky polygons to stunningly-rendered 3D environments, and has even made the transition to the big screen. The series turns twenty years old next month, and to celebrate Ive comprised a list of the 27 biggest WTF moments, from the very first Resident Evil on PS1 all the way up to Resident Evil 6, and everything in between.
