Capcom Resident Evil 5 (Xbox 360)

In 2009,[d] five years after the events of Resident Evil 4, Chris Redfield, now an agent of the Bioterrorism Security Assessment Alliance (BSAA), is dispatched to Kijuju in West Africa. He and his new partner Sheva Alomar are tasked with apprehending Ricardo Irving before he can sell a bio-organic w (BOW) on the black market. When they arrive, they discover that the locals have been infected by the parasites Las Plagas (those infected are called "Majini") and the BSAA Alpha Team have been killed. Chris and Sheva are rescued by BSAA's Delta Team, which includes Sheva's mentor Captain Josh Stone. In Stone's data Chris sees a photograph of Jill Valentine, his old partner, who has been presumed dead after a confrontation with Albert Wesker. Chris, Sheva and Delta Team close in on Irving, but he escapes with the aid of a hooded figure. Irving leaves behind documents that lead Chris and Sheva to marshy oilfields, where Irving's deal is to occur, but they discover that the documents are a diversion. When Chris and Sheva try to regroup with Delta Team, they find the team slaughtered by a BOW; Sheva cannot find Stone among the dead. Determined to learn if Jill is still alive, Chris does not report to headquarters.[6]

Continuing through the marsh, they find Stone and track down Irving's boat with his help. Irving injects himself with a variant of the Las Plagas parasite and mutates into a huge octopus-like beast. Chris and Sheva defeat him, and his dying words lead them to a nearby cave. The cave is the source of a flower used to create viruses previously used by the Umbrella Corporation, as well as a new strain named Uroboros. Chris and Sheva find evidence that Tricell, the company funding the BSAA, took over a former Umbrella underground laboratory and continued Umbrella's research. In the facility, they discover thousands of capsules holding human test subjects. Chris finds Jill's capsule, but it is empty. When they leave, they discover that Tricell CEO Excella Gionne has been plotting with Wesker to launch missiles with the Uroboros virus across the globe; it is eventually revealed that Wesker hopes to take a chosen few from the chaos of infection and rule them, creating a new breed of humanity. Chris and Sheva pursue Gionne but are stopped by Wesker and the hooded figure, who is revealed to be a brainwashed Jill. Gionne and Wesker escape to a Tricell oil tanker; Chris and Sheva fight Jill, subduing her and removing the mind-control device before she urges Chris to follow Wesker.[6]
