The modification adds a new Deadpool skin and a new weapon.
To install the skin, you will need "PluginMH" and the "All weapons in all levels" mod. Unzip the archive and copy the "DR2Evan" folder to the "Manhunt/data/skins" folder. Then copy the deadpoolkatana .dff and .txd files to "Manhunt/modloader/Extra Weapons/" (if you don't have a weapons folder, create one).
