Balanced Annihilation (BA) is currently the most popular game played using the Spring engine. BA is a mature mod and new versions feature only minor balance tweaks.
BA gameplay develops in stages of progressively heavier units with a growing economy. Many strategies are viable in BA, including focusing on map control, aggression, defense, air power, sea power, or mobility.
BA's lineage traces back to fan mods of the original Total Annihilation. It feels similar, and play is more balanced for diverse multiplayer strategies.
