If you are doing a first playthrough use this mod it combines the maps from both the main game and the expansion while overhauling some of the gameplay adding features that were originally cut from the game and adding more items and weapons to use in the loadout menu. If you have a mic you can use the speech recognition feature that comes with this mod so you can command your team with your voice which is really cool and unique since there are very few game that have something like this.
