So,I installed a custom map and didn't like the weapons it had and some of the zombie models. I have another custom map installed and want to trade an H&K G3 with an M14. However,I failed that attempt and ended up breaking the map. Luckily I had a backup. All I know how to do is replace the hud or add a new hud. I'm not looking to redistribute my modified maps soon. Could any of you guys teach me how?
