Thanks to JulioNib (the same guy who put together the insane Hulk mod from last year) you can tear through Los Santos as The CW's most charming speedster, Barry Allen. This script allows for full use of the Speed Force, including vibrating your hand through innocent victims' chests like the Reverse Flash.
Considering the amount of chaos you're capable of creating, this mod is actually seems like some kind of "Zach Snyder presents The Flash" simulator.
You can download the mod here.
It should be noted that the Flash, Reverse Flash, and Zoom models were created seperately by modders fungfung879 and OkaymanXXI.
