The game's on-rail, arcade shooter gameplay first featured in Resident Evil:The Umbrella Chronicles, has been radically upgraded in Resident Evil: The Darkside Chronicles. One of the major additions is a sub-screen which will allow for weapon configuration and use of recovery items regardless of time progression. A horde of new features including a new system that allows players to modify the difficulty level according to their playing skills will bring accessibility and fun to both the hardcore and casual gamer.
