Resident Evil 5 Development 2-4

Takeuchi said that about three years of "actual development time" were spent on the game, after a year devoted to concept and planning. At its development peak, about 110 people worked on the project. The decision for co-operative gameplay was made "part-way" through development, for a new experience in a Resident Evil game.^[17] Despite initial concern that a second player would dampen the game's tension and horror, it was later realized that a second player could increase tension in situations where one player had to be rescued.^[18] Takeuchi said that the decision to have both screens in their original 16:9 ratio in split-screen mode was influenced by a desire to avoid stacking the screens (which might be distracting), and the restriction on simultaneously moving and shooting was retained to increase player tension with the inability to move freely. Takeuchi cited the film Black Hawk Down and his experience working on Lost Planet: Extreme Condition as influences on Resident Evil 5.[17
