Resident Evil 5 is a third-person shooter video game developed and published by Capcom. It is the fifth major installment in the Resident Evil series, and was announced in 2005—the same year its predecessor Resident Evil 4 was released. Resident Evil 5 was released for the PlayStation 3 and Xbox 360 consoles in March 2009 and for Microsoft Windows in September that year. The plot involves an investigation of a terrorist threat by Bioterrorism Security Assessment Alliance agents Chris Redfield and Sheva Alomar in Kijuju, a fictional region of Africa. Chris learns that he must confront his past in the form of an old enemy, Albert Wesker, and his former partner, Jill Valentine.
