Ben appears in Resident Evil: The Darkside Chronicles, however, he is already killed by William Birkin before Leon, Ada, and Claire get to meet him. However, he managed to write the crucial information about the sewers on the cell wall before his death.
In the non-canon Leon A/Claire B Scenario, Ben is infected with a G-embryo instead of Irons, and dies after it erupts from his chest.
