Multiplayer Weapons in Single Player Mod (The Last of Us)

In just one afternoon I managed to find the files which hold weapon spawns, and then figure out how to change those weapons. So obviously I went straight for the multiplayer only weapons. Unfortunately it seems only the MP weapons from 1.00 will work in single player, as the weapons added in patches were never programmed to work with Joel, and cannot be spawned on a map. http://www.patreon.com/Freako
