If you download and install the free Battlefield 2 standalone mod known as Nations At War, you will gain access to hundreds of maps and a gameplay experience like you’ve never experienced in Battlefield 2. You do need your CD key from Battlefield 2 to play the mod. There are maps included in Nations At War that include the ability to not only fight against Xenomorphs and raptors but also give you the ability to play as them. In this video, I went both alien and raptor hunting. There are other cool things to discover in the Nations At War mod so be sure to check it out. Props to the mod team for their excellent work on what I believe is one of Battlefield 2’s best mods.
