Aegis Bastion
A portrait tower-defense survival game built around tactical loadouts, branching upgrades, permanent progression, and escalating waves.
Aegis Bastion:
Tower Defense
Construct prepared Turrets, acquire command Skills, and shape every sortie through level-up choices. Three-star upgrades branch into specialized paths, so the same loadout can evolve differently from one run to the next.
