Installer for Europa Barbarorum with Barbarian Invasion
..., and future. It will basically be the same EB as you're used to, only the AI will be much more advanced and challenging, and will be able to conduct naval invasions. The AI will also retrain units. If you only check this box, other mods can be installed after this installer without being screwed up.
Options to enable Unit Abilities, Night Battles, Torches, Hide Banners/Triangles, Alternative brightness settings, Giant tree removal, Victory Conditions.
