Full Invasion 2 is a co-op module for Mount & Blade: Warband where players come together to survive countless waves of invading enemies and bosses. It has been voted one of the most popular multiplayer modules within the community, and is still under active development to this day.
One of the most enjoyable multiplayer M&B mods. Co-op and tactic friendly. Huge variety of models and universes. There are some ugly textures like Faramir's face, Aragorn's armor, Swedish line infantry boots (I don't remember any other, but there were more :c ). But If you are looking for great multiplayer experience, this is the mod you're looking for ;)
