Jim Chapman's game play relies primarily on luck. He has three special abilities as of File #2, one more than the other survivors. The first ability is his aforementioned ability to Play Dead, which causes him to lay flat on the ground and not attract the attention of enemies around him. This raises his infection meter significantly, however. It also works well as a dodge move. His second ability is "Item Search" which lets him see all of the items on the map but doesn't reveal what they are until he finds them. His third ability is the Combo Swing, which gives him a multi-hit combo with swung melee weapons such as Wooden Poles and Iron Pipes.
Jim has the lowest Health of any male character in the game, he also has the highest infection rate of any character.
Jim's Coin and Lucky Coin allow him to raise his critical hit ratio if he gets Heads multiple times in a row. His critical hit ratio applies to all weapons, making him a very useful character.
