Galaxy Defense: Fortress TD

Galaxy Defense: Fortress TD is played in medium-length sessions focused on tower defense strategy and incremental upgrades. Progress is gated by both skill and spending, with a clear advantage given to those who invest heavily in the game. Interruptions can lead to lost progress, making it less ideal for casual, on-the-go play, and it's best suited for players who enjoy long-term progression systems and are willing to potentially spend money to remain competitive.
