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.
Great mod with a huge wealth of content. Each faction is as historically correct as is possible. One small problem is the "poll to change map/factions" feature which is prone to trolls ruining a 1.5 hour game, just because they died recklessly and want to respawn. Other than that, this is indeed the best mod ever made for Mount and Blade Warband.
