Hi, this is my first time using this website. I know absolutely nothing about modding, I might get a Jtagged xbox later, but right now I don't. I was wondering if there are any mods on a firefight map, I've seen speed mods and jump height mods but I am looking for a mod that has like a invincible tower or something to make it easy to get the Endure achievement. Also if something like this does exist do I have to have a jtag to play them or will just the party leader need to have one? Please help!
